"A Variational Study of the Random-field XY Model" 
HENRI ORLAND
CEN-Saclay and University Cergy-Pointoise  
 
Abstract: 
 
A disorder-independent Gaussian variational approach is applied to the
d}-dimensional ferromagnetic XY model in a random field.  The randomness 
yields a non extensive contribution to the variational free energy, implying
a random mass term in correlation functions.  The Imry-Ma low temperature result,
concerning the existence (d$>$4) or absence (d$<$4) of long-range order is obtained in
a transparent way.  The physical picture which emerges below d=4 is that of a 
marginally stable mixture of domains.  We also calculate within this variational
scheme, disorder dependent correlation functions, as well as the probability
distribution of the Imry-Ma domain size.

"The Past and Future of Reversible Computing" 
PROFESSOR EDWARD FREDKIN
 
Abstract:  
 
Recent work on quantum information theory and quantum computation
theory, as well as recent work on low-power logic, has led to a
resurgence of interest in reversible computation.  Unfortunately, even
though most of the basic results in reversible computation were worked
out in the late 70's, many of these results have never been
disseminated in any comprehensive form.  This has led to some
misconceptions about the supposed difficulty of building reversible
computers.  In this talk, I will present some of the main results of
reversible logic, including a discussion of a classical mechanical
model of reversible digital computation called the Billiard Ball
Model.  I plan to conclude with some comments on the relationship
between theoretical progress in understanding the physics of
computation, and theoretical progress in understanding nature.
 
Refreshments will be served following the Seminar.

Abstract: 
 
Observations of absorption lines in the spectra of quasars,
made particularly with the HIRES spectrograph on the Keck Telescope,
are providing new insights into the compositions of galaixes and
intergalactic clouds at early times and high redshifts.  Eventually it
will be possible to deduce the history of massive star formation back
to the epoch of galaxy formation.  At the same time parallel
information is being obtained using observations of the oldest stars
in our Galaxy.
