Bkt theory
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. This system is not expected to possess a normal second-order phase transition. This is because the expected ordered phase of … See more • KTHNY theory • Goldstone boson • Ising model • Lambda transition • Potts model • Quantum vortex See more There is an elegant thermodynamic argument for the Kosterlitz–Thouless transition.

WebBKT THEORY OF QUASI LONG-RANGE ORDER Topological Defects In two dimensions, low energy thermal uctuations (i.e. Goldstone modes) destroy true long-range order of any system with continuous symmetry. However, a new kind of long range order without explicit symmetry breaking may be achieved by introducing the notion of Web1 day ago · Numerical simulations of the full quantum properties of interacting many-body systems by means of field-theoretic Monte-Carlo techniques are often limited due to a sign problem.
