by JW Park — which observes BKT transition in a 2D trapped 87Rb gas. Thermal de Broglie wavelength at the critical temperature is reported to be ρC λ2 = 6 ± 2, in comparison.
by Z Hu2020Cited by 10 — The kinks at low fields, as denoted by the down arrows, suggest the transition from the BKT-like phase to the ordered phase (under the dome in ...
by AY Mironov2018Cited by 34 — The nature of the Berezinskii-Kosterlitz-Thouless (BKT) transition is different from the standard phase transitions described by the Landau ...
I couldn't find any simple texts explaining the Kosterlitz-Thouless transition. More specifically can someone explain the role of vortices in the transition. ...
