Free entropy is a quantity introduced 20 years ago by D. Voiculescu in order to investigate noncommutative probability spaces (e.g. von Neumann algebras). It is based on approximation by finite size matrices. I will describe the definition and main...

We consider two classes of \(n \times n\) sample covariance matrices arising in quantum informatics. The first class consists of matrices whose data matrix has \(m\) independent columns each of which is the tensor product of \(k\) independent \(d\)...

I will explain how Pitman's theorem on Brownian motion and the three dimensional Bessel process can be extended to several dimensions, and the connection with random matrices, and combinatorial representation theory, notably the Littelmann path...

We discuss some properties of a version of the one-dimensional totally asymmetric zero-range process in which a particle hops to the nearest neighbor site with rate proportional to \(1-q^n\), with \(n\) being the number of particles at the site. The...

We consider the totally asymmetric simple exclusion process with initial conditions and/or jump rates such that shocks are generated. If the initial condition is deterministic, then the shock at time t will have a width of order \(t^{1/3}\). We...

Edge reinforced random walk (ERRW) and vertex reinforced jump processes are history dependent stochastic process, where the particle tends to come back more often on sites it has already visited in the past. For a particular scheme of reinforcement...

Hirota relations in their various incarnations play an important role in both classical and quantum integrable systems, from matrix integrals and PDE's to one-dimensional quantum spin chains and two dimensional quantum field theories (QFT). The...
