The Kronmüller formula is used to qualitatively explain the coercivity of permanent magnets. Such simple expressions are useful for understanding elements that influence coercivity. This study attempts derive within framework Ginzburg-Landau theory. results revealed magnetic material was defined by slope free energy landscape. reduction parameter α anisotropy field Hk in depends on functional f...

A longstanding question in QCD is the origin of mass gap Yang-Mills sector QCD, i.e., without quarks. In Landau gauge this gap, and hence confinement, encoded a gluon propagator, which found both lattice simulations with functional approaches. While methods are well suited to unravel mechanism behind generation fully satisfactory answer has not yet been found. work we solve coupled Dyson-Schwin...

It can be shown that the dynamics of the Landau-Zener model can be accurately described in terms of the Kibble-Zurek theory of the topological defect production in nonequilibrium phase transitions. The simplest quantum model exhibiting the Kibble-Zurek mechanism is presented. A new intuitive description of Landau-Zener dynamics is found.

The Landau–de Gennes theory provides a successful macroscopic description of nematics. Cornerstone of this theory is a phenomenological expression for the effective free energy as a function of the orientational order parameter. Here, we show how such a macroscopic Landau–de Gennes free energy can systematically be constructed for a microscopic model of liquid crystals formed by interacting mes...

We calculate the relativistic entrainment matrix Yik at zero temperature for a nucleon-hyperon mixture composed of neutrons, protons, and and − hyperons, as well as electrons and muons. This matrix is analogous to the entrainment matrix (also termed mass-density matrix or Andreev-Bashkin matrix) of nonrelativistic theory. It is an important ingredient for modeling the pulsations of massive neut...
