Kosterlitz and Thouless won 2016 Nobel physics prize (shared with Haldane) for their development (in parallel with Berezinskii…) of a very neat mathematical model that describes phase transitions in nano-superconductors near the onset of the phenomenon. The transition in the BKT framework is governed by rather surprising vortex interactions rather than by the usual Cooper-pair dominancy. A nice inspiring boost to this fascinating research field.
