Reply to the Comment of S. Ayik and D. Lacroix, posted as arXiv:1909.1361v1, on the recent article "Fission Dynamics of 240Pu from Saddle-to-Scission and Beyond" by Bulgac et al, published as Phys. Rev. C 100, 034615 (2019)

I also suggest a possible formulation of a stochastic mean field approach free of the difficulties in the stochastic mean field model due to S. Expand abstract.

A Finite-Volume Method for Fluctuating Dynamical Density Functional Theory

We show through numerous applications that not only our scheme is able to accurately reproduce the statistical properties (structure factor and correlations) of the physical system, but, because of the multiplicative noise, it allows us to simulate energy barrier crossing dynamics, which cannot be captured by mean field...

Calculation of excited states via symmetry constraints in the Variational Quantum Eigensolver

The variational quantum eigensolver (VQE) requires specification of symmetries that describe the system, e.g. spin and number of electrons. Expand abstract.

Linear-Quadratic Mean-Field Reinforcement Learning: Convergence of Policy Gradient Methods

We prove rigorously the convergence of exact and model-free policy gradient methods in a mean-field linear-quadratic setting. Expand abstract.

Nature vs. Nurture: Dynamical Evolution in Disordered Ising Ferromagnets

In the mean-field setting with light-tailed couplings, the disorder averages out and the limiting trajectories of the magnetization and twin overlap match those of the homogenous Curie--Weiss model. Expand abstract.

A generalized variational principle with applications to excited state mean field theory

As an initial demonstration of how this approach can be useful in practice, we employ it to improve the optimization efficiency of excited state mean field theory by an order of magnitude. Expand abstract.

Linearly-Solvable Mean-Field Approximation for Multi-Team Road Traffic Games

It is shown via a mean-field approximation that a Nash equilibrium in the limit of a large population can be found by linearly solvable algorithms. Expand abstract.

Numerical resolution of McKean-Vlasov FBSDEs using neural networks

As a consequence, we obtain methods able to tackle both mean field games and mean field control problems in high dimension. Expand abstract.

Regularized pseudopotential for mean-field calculations

After discussing the penalty function used to adjust parameters, we discuss predictions for binding energies of spherical nuclei calculated at the mean-field level, and we compare them with those obtained using the standard Gogny D1S finite-range effective interaction. Expand abstract.
