Bogoliubov corrections and trace norm convergence for the Hartree dynamics

Abstract: We consider the dynamics of a large number N of interacting, nonrelativistic bosons in the mean field limit. In order to describe the fluctuations around the mean field Hartree state, we int...

Kinetic and hydrodynamic limits for chains of harmonic oscillators

Abstract: I will present two new results about macroscopic behavior of chains of harmonic oscillators.1) The strain, momentum and energy of a chain of harmonic oscillators with random masses, even out...

Emergent dynamics for a model of quantum synchronization

Abstract: In this talk I will discuss a model (introduced by Lohe, J. Phys. A 2010) describing quantum synchronization. More specifically, this is a system of coupled nonlinear Schrödinger equations w...

Stability of quantum many-body systems with point interactions

Abstract: We present a proof that a system of NN fermions interacting with an additional particle via point interactions is stable if the ratio of the mass of the additional particle to the one of the...

Particle Creation at a Point Source by Means of Interior-Boundary Conditions

Abstract: We consider a way of defining quantum Hamiltonians involving particle creation and annihilation based on an interior-boundary condition (IBC) on the wave function, where the wave function is...

A gradient flow approach for linear Boltzmann equations

Abstract: We introduce a gradient flow formulation of linear Boltzmann equations. Under a diffusive scaling we derive a diffusion equation by using the machinery of gradient flows. This is a joint wor...

Two characterizations of Dirichlet-Ferguson measures

We consider the Dirichlet-Ferguson (DF) measure, a random probability on a locally compact Polish space X introduced by Ferguson in [1]. The measure has ever since found many applications, widely rang...

Well-posedness of semilinear SPDEs with singular drift: a variational approach

Well-posedness is proved for singular semilinear SPDEs on a smooth bounded domain D in R^n. The linear part is associated to a coercive linear maximal monotone operator on L^2(D) while the drift is re...

A test of Gaussianity based on the Euler characteristic of excursion sets

We deal with a stationary isotropic random field X:R^d→R and we assume it is partially observed through some level functionals. We aim at providing a methodology for a test of Gaussianity based on t...

Conditional iid structures in exchangeable multivariate distributions: from Marshall-Olkin to 'load sharing' $

The discovery of a conditional iid structure allows the understanding of the dependence contained in a d-v$...

Multidimensional reflected random walk - some results and many questions

Let (Y_n,V_n) be i.i.d. distributed, with the components r and s-dimensional, respectively. Reflected random walk starting at a point x of the positive r-dimensional orthant is defined recursively b...

More random walks on random walks

We consider a Poissonian distribution of particles performing independent simple random walks. Simultaneously, on top of this system, a random walker evolves with a drift to the right when it is on to...
