Experiments in hcp-Os have reported peculiarities in the ratio In physicsand probability theory, mean-field theory(aka MFTor rarely self-consistent field theory) studies the behavior of high-dimensional random (stochastic) models by studying a simpler model that approximates the original by averaging over degrees of freedom(the number of values in the final calculation of a statisticthat are free to vary). The mean-field theory begins with the van der Waals equation of state (van der Waals 1873) for the liquid-gas transition and the Weiss (1906) molecular field theory for ferromagnetism.

While the mean-field theory often seems too crude, the exact solutions are too complicated. A peculiar feature of critical The self-consistent mean-field approximation is derived using the effective nucleon–nucleon Skyrme-type interaction. The many-body problem is described next in terms of the Wigner phase space of the one-body density, which provides a basis for semi-classical approximations and leads to kinetic equations. I found some intuitions that might answer this; based on the definition of "mean-field" at Wikipedia, mean field theory (MFT also known as self-consistent field theory) studies the behaviour of large and complex stochastic models by studying a simpler model.

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.

More specifically, we scatter two solitons off of each other (in our setup, the bright solitons play the role of a classical analog to the quantum photons of the original experiment), while the role of the beam splitter is played by a repulsive 2021-02-19 · Many mean-field theories are proposed for studying the non-equilibrium dynamics of complex systems, each based on specific assumptions about the system’s temporal evolution. Here, Aguilera et al The study of nonequilibrium phenomena in correlated lattice systems has developed into one of the most active and exciting branches of condensed matter physics. 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.

The scheme envolves a cascading mean-field description of the magnetization field followed by an appropriate linearization of the magnetization function. This allows to greatly decouple the effects coming into the magnetization field from the micro-, meso-, and macroscale in the composite samples with arbitrary microstructures and shapes.

These models do not take into account the shape or the orientation of the inclusions; however, they provide upper and lower bounds of the macro stiffness … In this section the magnetization of the isotropic Heisenberg model in the mean field approximation (german Molekularfeldnäherung or mittlere Feldnäherung) is derived. The Heisenberg model is a very … However, use of the meanfield inhomogeneous Flory–Huggins model (7), originally developed for polymer-solvent interactions, may provide a more accurate description of solvation. Here we use a meanfield theory to calculate the free energy of a static experimentally determined protein structure.
