Universality in nonequilibrium condensation of exciton-polaritons
Michal Matuszewski, Emilia Witkowska
We investigate the process of condensation of exciton-polaritons in a one-dimensional nanowire, predicting spontaneous formation of domains of uncondensed excitons and condensed po…
Double universality of a quantum phase transition in spinor condensates: the Kibble-Żurek mechanism and a conservation law
Tomasz Swislocki, Emilia Witkowska, Jacek Dziarmaga +1
We consider a phase transition from antiferromagnetic to phase separated ground state in a spin-1 Bose-Einstein condensate of ultracold atoms. We demonstrate the occurrence of two…
Spontaneous solitons in the thermal equilibrium of a quasi-one-dimensional Bose gas
T. Karpiuk, P. Deuar, P. Bienias +5
Solitons, or non-destructible local disturbances, are important features of many one-dimensional (1D) nonlinear wave phenomena, from water waves in narrow canals to light pulses in…
