The Kosterlitz-Thouless transition (also known as the Berezinskii-Kosterlitz-Thouless (BKT) phase transition)[1] [2] [3] [4] is a phase transition found in the two-dimensional XY model. Below the transition temperature, , the system plays host to a 'liquid' of vortex-antivortex pairs that have zero total vorticity. Above these pairs break up into a gas of independent vortices.
For the XY model the critical temperature is given by (Eq.4 in [4]):
where is the spin-spin coupling constant. This can be obtained as (Eq.58 in [4]):
