“…However, whereas the GPE conventionally describes the condensate only, ψ(r, t) now describes the entire multi-mode 'classical' gas [28,29]. The classical field method has been used to model phenomena beyondmean-field effects, including thermal equilibration dynamics [36,38,40,41], condensate fractions [39], critical temperatures [42], correlation functions [43], spontaneous production of vortex-antivortex pairs in quasi-2D gases [44], thermal dissipation of vortices [45], and related effects in binary condensates [40,46,47].…”
