TīmeklisLandau theory in physics is a theory that Lev Landau introduced in an attempt to formulate a general theory of continuous (i.e., second-order) phase transitions. It can also be adapted to systems under externally-applied fields, and used as a quantitative model for discontinuous (i.e., first-order) transitions. TīmeklisWe study topological D-branes of type B in N=2 Landau-Ginzburg models, focusing on the case where all vacua have a mass gap. In general, tree-level topological string theory in the presence of topological D-branes is described mathematically in terms of a triangulated category. For example, it has been argued that B-branes for an N=2 …

TīmeklisAccording to the Ginzburg-Landau theory, a rotating disk of type II superconductor at the phase transition with low temperature (e.g., 70K) generates a scalar field [19-20, 24-30] that varies the equivalent gravitational constant along with the Earth scalar field in and around the superconductor and thus shields the gravitational field of the Earth.
