Specifically, spiral mean-field theory is applied to a 17-band d-p model constructed from the maximally localized Wannier functions. Our itinerant-model approach shows that the most stable spiral magnetic state has an ordering vector near Q = (0.15,0.15,0), consistent with neutron scattering Random Matrix Theory beyond the Mean-Field Class Horng-Tzer Yau Harvard University With P. Bourgade, L. Erd}os and J. Yin 2020-06-17 · To understand the magnetism of VSe 2, whose monolayer form has recently been reported to be a room temperature ferromagnet, here, the combined method of conventional density functional theory with dynamical mean-field theory has been adopted. Kinetics as the link between atomic scale properties and macroscopic functionalities is indispensable in describing surface chemical reactions and computation-based rational design of catalysts. Kinetic Monte Carlo (KMC) on the explicit lattice can resolve events taking place on the catalytic surfaces at the atomic level.

This research field provides rich new insights that could not be obtained from the study of equilibrium situations, and the theoretical understanding of the physics often requires the development of new concepts and methods.

We show that the mean-field approximation of such a game leads to the so-called linearly solvable Markov decision process, implying Universality of the mean-ﬁeld for the Potts model 1.1 Mean-ﬁeld method Let P([q]n) denote the space of probability measures on [q]n.For any two measures μ,ν ∈ P([q]n)deﬁne the Kullback–Leibler divergence between μ and ν by AUGMENTED LAGRANGIAN METHODS FOR TRANSPORT OPTIMIZATION, MEAN-FIELD GAMES AND DEGENERATE PDES JEAN-DAVID BENAMOU AND GUILLAUME CARLIER Abstract. Many problems from mass transport can be reformulated The relating of deterministic, mean-field models into network models, where epidemic spread occurs between interconnected susceptible and infectious individuals or populations, requires careful consideration.

We prove the existence and pathwise uniqueness of the solution for stochastic predator-prey systems in the mean-field limit. Then we show that the solution of the mean-field equation is a periodic measure. Finally, we study the fluctuations of the periodic in distribution processes when the white noise For the facile use of liquid metal composites (LMCs) for soft, stretchable and thermal systems, it is crucial to understand and predict the thermal conductivity of the composites as a function of liquid metal (LM) volume fraction and applied strain. Weyl semimetals are three-dimensional, topologically protected, gapless phases which show exotic phenomena such as Fermi arc surface states or negative magnetoresistance. It is an open question whether interparticle interactions can turn the topological semimetal into a topologically nontrivial Mott-insulating phase.

We investigate an experimentally motivated model for Weyl physics of cold 2014-06-24 Speaker: Subhabrata Sen, Harvard University Abstract: Variational approximations provide an attractive computational alternative to MCMC-based strategies for approximating the posterior distribution in Bayesian inference.Despite their popularity in applications, supporting theoretical guarantees are limited, particularly in high-dimensional settings. A generalized Lugiato–Lefever equation is numerically solved with a Newton–Raphson method to model Kerr frequency combs. We obtain excellent agreement with past experiments, even for an octave-spanning comb.
