Condensation & BKT transition in 2d defocusing nonlinear Schrödinger equation.
Sergey Nazarenko (Mathematics Institute, University of Warwick)
I will consider a 2D nonlinear Schrödinger equation model in a periodic box and truncated in Fourier space and study condensation phenomenon, Berezinskii-Kousterlitz-Thouless transition, and their links with the Wave Turbulence theory.
