Title: Computer Applications
in the Classroom: Some Examples
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
Students in the physical sciences
frequently come to chemistry and physics
classes with misconceptions of important
concepts. Those concepts which students
have significant difficulty understanding
are most often abstract in nature. Students
have few life experiences for many of these
abstract concepts so their intuition is not
very sophisticated. For example, chemistry
students are asked to interpret macroscopic
behavior in terms of microscopic models of
matter. Students find these models difficult
to visualize. Equally difficult is trying
to communicate the dynamic nature of these
models.
Computer animations can help provide
qualitative views of these models.
Although limited in their flexibility
these animations can provide useful views
which can help students to enhance their
understanding of chemical phenomena.

Title: Subatomic Microscopy and
Micromanipulation
Abstract:
By the use of picosecond and femtosecond
electromagnetic pulses it is possible to
extend microscopy to examine and manipulate
the electrons within an atom. In this
lecture we will discuss what an atomic
electron "looks like," review recent work
in which a single atomic electron is
excited into a state that is of the form
of a Young's double-slit interferometer,
and speculate how one may be able to
store large amounts of information within
a single atom. The lecture will be given
at a general level appropriate for
undergraduates as well as graduate
students and faculty.

Title: Subsurface Damage in
Ultraprecision Machined
Semiconductors
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
The ultraprecision finishing of
semiconductor materials continues to
receive attention because of the critical
need to provide surfaces with both extreme
control of surface roughness and flatness
as well as minimized damage of subsurface
crystalline structure. Interest in
assessing subsurface damage is motivated
by the limitations which lattice disorder
pose on device performance, and the fact
that the extent of subsurface damage may
provide a critical complement to surface
finish in assessing machining performance.
The objective of the present work is to
examine the extent and distribution of
subsurface damage in ultraprecision
machined semiconductors by the use of
ion channeling. Single crystal (0001)
oriented CdS was single point diamond
turned over a range of depths of cut from
0.1-10 micrometers, and subsurface lattice
disorder was examined for regions cut
parallel to, and 30 degrees off, a
preferred cleavage plane. The energy
spectrum of 2 MeV 4 He + ions
backscattered from the crystal surface
was used to obtain depth profiles of
lattice disorder.

Title: Using Physics Education Research
and Microcomputer-Based
Laboratories to Improve
the Effectiveness of the
Introductory Physics Curriculum
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
Several innovative projects using
micro-computer based laboratory (MBL)
tools and active learning approaches
have been developed to improve the
instruction of the introductory physics
courses. These projects have been
designed using a coordinated program
of research to address the misconception
students bring with them to the classroom.
Northern Oklahoma College is currently
implementing a new curriculum program
using these innovative projects as the
best approach to create an active learning
environment through the integration
of conceptual exercises, problem solving,
MBL tools, and new teaching methods. This
colloquium will present several of the
developments from this program and the
positive impact it has had on student
learning.

Title: From Guided Missiles to
Quantum Tunnelling ---
Why Physicists in Industry?
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
Answers will be given to the title
question. An idealistic answer will first
be given followed by an answer in terms of
reality as experienced by the speaker. Our
ever changing cultural environment will be
discussed. The good, the bad, and the ugly
will be touched upon. Recommendations will
be made concerning how to prepare for all
three.
The formal part of the presentation will
be brief. The most important part will
stem from questions from the audience. The
speaker is not likely to answer all your
questions, but is certain that he will not
be able to answer them if not asked, so
come prepared.
Dr. Dutcher has significant academic,
research, industrial, and managerial
experience, having been on the faculty
of the University of Florida, been a
member of Bell Labs, and with fifteen
years of experience in high-level
development, management, and marketing.

Title: Development and Characterization of
Two-Photon Lasers and Amplifiers
Abstract:
Two-photon lasers have intrigued
researchers for years because the
dynamical behavior of this new class
of highly nonlinear quantum oscillator
is very different from normal one-photon
lasers. Unfortunately, tests of the
numerous, often conflicting, predictions
about their behavior have been hindered
by the difficulty in realizing practical
two-photon amplifiers. To this end,
we have recently observed ~30%
two-photon optical amplification of a
continuous-wave probe laser field
propagating through a potassium vapor
driven by a strong pump laser tuned near
the 4S_{1/2}->4P_{1/2}(D1) transition
frequency. I will review the physics
of two-photon lasers and describe our
efforts toward the development of
two-photon lasers based on our new
amplifier.

Time: 4:00 PM
Place: PS 110
Title: Giant Enhancement Effects in
Ordinary and Magneto-Coulomb Drag
in Double Quantum Well Systems
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
When two quantum wells are placed adjacent
to each other at a distance where tunneling
is forbidden but inter-well Coulomb
interactions are significant, driving a
current J_1 in the first well drags
carriers in the second, which creates an
electric field response E_2 if the current
J_2 is set to zero. We investigate
theoretically the drag transresistivity
rho_{21} in the absence and presence of a
magnetic field perpendicular to both layers.
For B=0, the plasmon mediated interlayer
interaction due to the coupled collective
modes of the system can increase the
rho_{21} by up to an order of magnitude at
intermediate temperatures. For B not equal
to 0, in the interplateau regions of the
integer quantum Hall effect, we find that
rho_{21} is enhanced by approximately
50-100 times over that of the B=0 at low
temperatures. The presence of both
electron-electron interactions and
Landau quantization results in
(i) a twin-peaked structure of
rho_{21}(B) in the inter-plateau
regions at low temperatures, and,
(ii) for the chemical potential at the
center of a Landau level band, a peaked
temperature dependence of rho_{21}(T)/T^2.

Title: Domain Structure of
Polymer Mixtures and Emulsions
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM.
Abstract:
I will discuss experiments using confocal
optical microscopy to make novel
3-dimensional, real space measurements of
domain structure in mixtures of polymeric
fluids. With this technique, one can
obtain information that is not accessible
in scattering experiments. We have
measured the structure of binary polymer
mixtures undergoing off-critical phase
separation, in which polydisperse
minority phase droplets grow in a matrix
of the majority phase. By measuring the
size distribution of these droplet domains,
as well as the spatial correlations
between them, it is possible to determine
the dominant mechanism of domain growth.
If diblock copolymers are added to these
phase separating polymer mixtures, the
diblocks act as surfactants, stabilizing
the droplet domains at a finite preferred
size. This ternary mixture is the
polymeric analogue of a microemulsion, but
with a much larger characteristic length
scale than conventional microemulsions.

Title: Experimental studies of
liquid surface structure
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM,
where also the traditional student-speaker
informal discussion is scheduled 3:30-3:45.
Abstract:
At the liquid/vapor surface of a critical
binary liquid mixture one can find either
an adsorption layer or a wetting layer.
We specify the differences between these
two types of surface structure and then
examine the kinetics of surface nucleation
and growth of wetting droplets after a
temperature quench into the two phase
regime. If time permits we will also
examine a new type of surface microscopy
which can image micron size drops with
0.1nm thickness resolution.

Title: Bistability and Instabilities
in Nonlinear Optical Resonators
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:00 PM.
Abstract:
Optical bistability is the existence of
two possible stable output intensities,
for a single input intensity, when a
laser beam is passed through an optical
resonator containing a near-resonant
nonlinear medium. Optically bistable
systems, which can be macroscopic,
microscopic, or mesoscopic, are of both
fundamental and practical significance.
Under certain circumstances, the
transmission of an optically bistable
system can become unstable. This talk
will describe an experimental search for
one of the most basic instabilities of
such a delay-differential system, using
a ring resonator containing a cell of
molecular gas and being driven by a
continuous-wave carbon-dioxide laser.
One surprising result of this experiment
was the verification that optical
processes involving the complex molecular
level structure can be understood
successfully in terms of a two-level
model. Two experimental feasibility
studies will also be described; these
represent predictions of new means of
achieving bistability and instability in
nonlinear resonators.

Title: Liquid-Liquid And Liquid-Solid
Phase Boundaries Of Eye Lens
Protein Solutions
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM.
Abstract:
Understanding the thermodynamic properties,
including the phase transitions, of
concentrated solutions of biological
macromolecules is important for
understanding the living cell in health
and disease. Liquid-liquid phase
separation, the solution analogue of
liquid-vapor equilibrium, occurs in the
cytoplasm of the lens of the eye. The
associated phase boundary can serve as
a marker for molecular changes associated
with cataract disease. We present
experimental and mean-field theoretical
investigations of the equilibrium
properties of eye lens protein and water
solutions, including the coexistence
curves for liquid-liquid separation
and the solid-liquid phase boundaries.

Title: Experiments on the Multiples
Superconducting Phases
of (U,Th)Be13
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM.
Abstract:
Our understanding of superconductivity has
been challenged by the discoveries over
the past fifteen years of several new
classes of superconductors. The new
materials suggest that the conventional
picture, in which a phonon-mediated
attraction between electrons leads to
s-wave electron pairs, may not always hold.
There is the possibility of both
non-s-wave uperconductivity and of new
mechanisms for the electron attraction.
Theoretical speculation and experiments
testing the nature of the superconductivity
have abounded, particularly in the high-Tc
materials, but few of the questions are
resolved. My work involves the heavy
fermion superconductors, which by all
indications are unconventional.
Unusual behaviors observed to date
include large anisotropies,
coexistence of magnetic order and
superconductivity, and quantities with
power-law temperature dependences
indicative of energy gap nodes.
Most surprisingly, two of the heavy
fermion systems have phase transitions
within the superconducting state.
I will describe my work on establishing
the phase diagram of (U,Th)Be13 and on
characterizing the different phases.
Specific heat measurements under pressure
established a new phase boundary.
The specific heat data, and additional
measurements on magnetization, also
support a proposal that in one of
the superconducting phases the order
parameter violates time reversal symmetry.

Title: Noether's Theorem, Adiabatic
Invariance, Undergraduate
Research, and the SPS
(Organized by SPS)
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM.
Abstract:
A discussion of Noether's Theorem that
relates symmetries to conservation laws,
then applies it to "adiabatic invariance."
The latter is an example of a project on
which Dr. Neuenschwander has worked with
undergraduates, which would move the
discussion into undergraduate research
as one of six roles that the Society
of Physics Students has in the physics
community. These six roles would be the
topic of the last one-third of the
presentation.

Title: 2D Fluid Dynamics Experiments
with Flowing Soap Films
Refreshments served before Colloquium in
Physical Sciences, Room 147, at 3:30 PM.
Abstract:
Everyone has marveled over soap films at
one time or another. Soap films are not
merely pleasing to the eye. They are graphic
demonstrations of interference of light,
minimal surfaces, and elastic normal modes.
This lecture will demonstrate that soap
films are also excellent for studying 2D
hydrodynamics. Experiments have been
conducted with a novel flow channel in
which a soap film flows between two
vertical wires. Obstacles placed in the
film produce a variety of flow patters
in their wakes. With increasing Reynolds
number the flow around a cylinder shows
laminar behavior, the celebrated von Karman
vortex street, period doubling, and finally
turbulence. The behavior of the laminar flow
was studied in detail in order to understand
the fundamental properties of soap as a
model 2D fluid. Quantitative measurements
of 2D grid generated turbulence will be
discussed in terms of its signatures which
include intermittency, and cascades of
energy and enstrophy.
