Since its inception, apart from applications in condensed matter physics, the theory has been actively applied in other branches of physics, such as high energy physics, atomic physics, nuclear physics, statistical physics, nonlinear systems, etc.
The Berezinskii–Kosterlitz–Thouless transition (BKT transition) is a phase transition of the two-dimensional (2-D) XY model in statistical physics. It is a transition from bound vortex-antivortex pairs at low temperatures to unpaired vortices and anti-vortices at some critical temperature. The transition is … See more The XY model is a two-dimensional vector spin model that possesses U(1) or circular symmetry.
