Non-equilibrium Dynamics and Random Matrices

Exponential asymptotics, generalized Borel summability and applications
4:00pm|S-101

I will describe the general ideas behind exponential asymptotic methods, their recent developments, and a number of open problems that were solved in the last few years using them, such as the behavior of Hydrogen atoms in time periodic fields and...

Acquiring Knowledge Through Information Loss
Jürg Fröhlich
2:00pm|S-101

After a short introduction to some ideas on quantum probability theory I discuss the roles played by loss of information and entanglement in the emergence of facts in quantum-mechanical experiments and observations. Besides explaining why...

KPZ Question & Answer session
I. Corwin, J. Quastel, H. Spohn
2:30pm|S-114

This will be an informal session in which we will try to answer questions from the audience on topics around KPZ.

Local eigenvalue statistics at the edge of the spectrum: an extension of a theorem of Soshnikov
Alexander Sodin
2:00pm|S-101

We discuss two random decreasing sequences of continuous functions in two variables, and how they arise as the scaling limit from corners of a (real / complex) Wigner matrix undergoing stochastic evolution. The restriction of the second one to...

KPZ line ensemble
Ivan Corwin
11:00am|S-101

We construct a \(\mathrm{KPZ}_t\) line ensemble -- a natural number indexed collection of random continuous curves which satisfies a resampling invariance called the H-Brownian Gibbs property (with \(H(x)=e^x\)) and whose lowest indexed curve is...

Polynomial chaos and scaling limits of disordered systems
Nikolaos Zygouras
2:00pm|S-101

Inspired by recent work of Alberts, Khanin and Quastel, we formulate general conditions ensuring that a sequence of multi-linear polynomials of independent random variables (called polynomial chaos expansions) converges to a limiting random variable...

Diffusion for the (Markov) Anderson model
2:00pm|S-101

I will discuss the proof by Yang Kang and myself of diffusion for the Markov Anderson model, in which the potential is allowed to fluctuate in time as a Markov process. However, I want to highlight the method of the proof more than the result itself...

Diffusion and superdiffusion of energy in one dimensional systems of oscillators
Stefano Olla
3:00pm|Dilworth Room

We consider a system of harmonic oscillators with stochastic perturbations of the dynamics that conserve energy and momentum. In the one dimensional unpinned case, under proper space-time rescaling, Wigner distribution of energy converges to the...

All-order asymptotics in beta ensembles in the multi-cut regime
Gaetan Borot
11:00am|S-101

Based on joint work with A. Guionnet (MIT). The beta ensemble is a particular model consisting of N strongly correlated real random variables. For specific values of beta, it is be realized by the eigenvalues of a random hermitian matrix whose...
