Non-equilibrium Dynamics and Random Matrices

A quantitative Brunn-Minkowski inequality and estimates on the the remainder in the Riesz rearrangement inequality
Eric Carlen
2:00pm|S-101

We prove a quantitative Brunn-Minkowski inequality for sets \(E\) and \(K\), one of which, \(K\), is assumed convex, but without assumption on the other set. We are primarily interested in the case in which \(K\) is a ball. We use this to prove an...

Multi-component KPZ equations
11:00am|S-101

The stochastic Burgers equation (equivalent to the one-dimensional KPZ equation) is a hyperbolic conservation law with random currents. In applications, one often has to deal with several conservation laws, a little explored case. We discuss several...

Rigidity phenomena in random point sets and applications
Subhroshekhar Ghosh
11:00am|S-101

In several naturally occurring (infinite) point processes, we show that the number (and other statistical properties) of the points inside a finite domain are determined, almost surely, by the point configuration outside the domain. This curious...

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...
