Thouless, academic and author of Straight kosterlitz and Crooked Thinking. The Kosterlitz-Thouless transition, or Berezinsky-Kosterlitz-Thouless transition, is a special transition seen in the XY model for interacting spin systems in 2 spatial dimensions. The first is the ABJM theory with flavor and thouless the second is kosterlitz a flavored (1,1) little string theory. We study a prototypical model for the metal to insulator transition of spinless interacting fermions coupled to electronic baths and driven out of equilibrium by a longitudinal static electric field.
