Universal Kibble–Zurek scaling in an atomic Fermi superfluid

K Lee, S Kim, T Kim, Y Shin - Nature Physics, 2024 - nature.com
Abstract The Kibble–Zurek mechanism is a theoretical framework that describes the
formation and scaling of topological defects in symmetry-breaking phase transitions. It was …

Universal early coarsening of quenched bose gases

J Goo, Y Lee, Y Lim, D Bae, T Rabga, Y Shin - Physical Review Letters, 2022 - APS
We investigate the early coarsening dynamics of an atomic Bose gas quenched into a
superfluid phase. Using a two-step quench protocol, we independently control the two …

Quench-induced spontaneous currents in rings of ultracold fermionic atoms

DG Allman, P Sabharwal, KC Wright - Physical Review A, 2024 - APS
We have observed the spontaneous appearance of currents in a ring of ultracold fermionic
