Mean-field reflected backward stochastic differential equations

In this paper, we study a class of reflected backward stochastic differential equations (BSDEs) of mean-field type, where the mean-field interaction in terms of the distribution of the $Y$-component of the solution enters in both the driver and the lower obstacle. Expand abstract.

Structured Mean-field Variational Inference and Learning in Winner-take-all Spiking Neural Networks

In these models, we do away with symmetric synaptic weights previously assumed for \emph{unstructured} mean-field variational inference by learning both the feedback and feedforward weights separately. Expand abstract.

Some aspects of the inertial spin model for flocks and related kinetic equations

Finally, in the case of non-constant interactions, we derive the kinetic equation for the mean-field limit of the model in the absence of thermal noise, and explore its macroscopic behavior by analyzing the mono-kinetic solutions. Expand abstract.

Superradiant optomechanical phases of cold atomic gases in optical resonators

We theoretically analyze superradiant emission of light from a cold atomic gas, when mechanical effects of photon-atom interactions are considered. Expand abstract.

Inter-component asymmetry and formation of quantum droplets in quasi-one-dimensional binary Bose gases

A quantum droplet is an ultradilute liquid state which emerges from the competitive interplay of two Hamiltonian terms, the mean-field (MF) energy and beyond-MF correction in a weakly interacting binary Bose gas. Expand abstract.

Metal-Insulator and Magnetic Phase Diagram of Ca$_2$RuO$_4$ from Auxiliary Field Quantum Monte Carlo and Dynamical Mean Field Theory

Layered perovskite ruthenium oxides exhibit a striking series of metal-insulator and magnetic-nonmagnetic phase transitions easily tuned by temperature, pressure, epitaxy, and nonlinear drive. Expand abstract.

Does one-step replica symmetry breaking occur in p-spin Ising models outside mean-field theory?

The fully-connected Ising $p$-spin model has for $p >2$ a discontinuous phase transition from the paramagnetic phase to a stable state with one-step replica symmetry breaking (1RSB). Expand abstract.

Statistical Inference in Mean-Field Variational Bayes

We also propose a new class of variational weighted likelihood bootstrap (VWLB) methods for quantifying the uncertainty in the mean-field variational inference. Expand abstract.

Mean-field tricritical polymers

We provide an introductory account of a tricritical phase diagram, in the setting of a mean-field random walk model of a polymer density transition, and clarify the nature of the density transition in this context. Expand abstract.
