This study investigates the spontaneous emergence of quantum turbulence in newly formed Bose-Einstein condensates using numerical simulations based on the Kibble-Zurek mechanism. By establishing nonequilibrium universality through specific scaling laws, the research provides fundamental insights into topological defect formation during continuous phase transitions driven by thermal quenches. The findings advance our theoretical understanding of non-equilibrium dynamics within quantum many-body systems without immediate commercial application implications.

Spontaneous Quantum Turbulence in a Newborn Bose-Einstein Condensate via the Kibble-Zurek Mechanism

arXivJuly 24, 20261 min read

arXiv:2506.21670v3 Announce Type: replace-cross Abstract: The Kibble-Zurek mechanism (KZM) predicts the spontaneous formation of topological defects in a continuous phase transition driven at a finite rate. We propose the generation of spontaneous quantum turbulence (SQT) via the KZM during Bose-Einstein condensation induced by a thermal quench. Using numerical simulations of the stochastic projected Gross-Pitaevskii equation in two spatial dimensions, we describe the formation of a newborn Bose-Einstein condensate proliferated by quantum vortices. We establish the nonequilibrium universality of SQT through the Kibble-Zurek and Kolmogorov scaling of the incompressible kinetic energy.
