title: The critical curve for pinning of random polymers. A large deviations approach. 
We consider a
directed random polymer interacting with an interface that carries
random charges some of which attract while others repel

speaker: Jeremy Clark (KU Leuven) 
title: Central limit theorem for an inhomogeneous linear Boltzmann equation at infinite temperature. 
I will
discuss a class of linear Boltzmann equations describing a classical
particle in a spatially inhomogeneous noisy environment. The
dynamics includes a periodic potential field and a noise whose
statistics depend periodically on the location of the particle.
The model is set at infinite temperature and thus does not have energy
relaxation. In the long time limit, a central limit theorem
emerges for the joint distribution in momentum and position in which
the limiting form depends only on a spatial average of the noise.
I will finish by defining and discussing the quantum analog for the
problem. The quantum version has appeared in the physics
literature on atoms in an optical lattice.
