Series: Other Talks

Emory University, Georgia Tech and Georgia State University, with support from the
National Science Foundation and the National Security Agency, will continue the
series of mini-conferences and host a series of 9 new mini-conferences from
2014-2017. The 12th of these mini-conferences will be held at
Georgia Tech during April 26-27, 2014. The conferences will stress a variety of
areas and feature one prominent researcher giving 2 fifty minute lectures and 4
outstanding researchers each giving one fifty minute lecture. There will also be
several 25 minute lecturers by younger researchers or graduate students.

We
consider a diffusion on a potential landscape which is given by a
smooth Hamiltonian in the regime of small noise. We give a new proof of
the Eyring-Kramers
formula for the spectral gap of the associated generator of the
diffusion. The proof is based on a refinement of the two-scale approach
introduced by Grunewald, Otto, Villani, and Westdickenberg and of the
mean-difference estimate introduced by Chafai and Malrieu. The Eyring-Kramers
formula follows as a simple corollary from two main ingredients : The
first one shows that the Gibbs measure restricted to a domain of
attraction has a "good" Poincaré constant mimicking the fast convergence
of the diffusion to metastable states. The second ingredient is the
estimation of the mean-difference by a new weighted transportation
distance. It contains the main contribution of the spectral gap,
resulting from exponential long waiting times of jumps between
metastable states of the diffusion. This new approach also allows to
derive sharp estimates on the log-Sobolev constant. This is joint work with Andre Schlichting.

Using basic linear algebra as a natural language of special relativity, and assuming very little knowledge of physics, we present a novel linear-algebraic derivation of the Lorentz transformation. Through the geometry of Minkowski diagrams, we analyze properties and paradoxes of special relativity including the Twin paradox and the bug-rivet paradox.Dr. de Pillis is a renowned cartoonist and animator, and his new book entitled Illustrated Special Relativity Through its Paradoxes is a fusion of Linear Algebra, Graphics, and Reality.

Host: Dan Goldman, Physics

I introduce a class of dynamical systems which exhibit motion in their
lowest-energy states and thus spontaneously break time-translation
symmetry. Their Lagrangians have nonstandard kinetic terms and their
Hamiltonians are multivalued functions of momentum, yet they are perfectly
consistent and amenable to quantization. Possible applications to
condensed matter systems and cosmology will be discussed.
