Circulation Statistics and Migdal Area Rule Beyond the Kibble-Zurek Mechanism in a Newborn Bose-Einstein Condensate
Matteo Massaro, Seong-Ho Shinn, Mithun Thudiyangal +1
The Kibble-Zurek mechanism (KZM) predicts that a newly formed superfluid prepared by a finite-time thermal quench is populated with vortices. The universality of vortex number stat…
Electrodynamics of Vortices in Quasi-2D Scalar Bose-Einstein Condensates
Seong-Ho Shinn, Adolfo del Campo
In two spatial dimensions, vortex-vortex interactions approximately vary with the logarithm of the inter-vortex distance, making it possible to describe an ensemble of vortices as…
Stoner-Wohlfarth switching of the condensate magnetization in a dipolar spinor gas and the metrology of excitation damping
Seong-Ho Shinn, Daniel Braun, Uwe R. Fischer
We consider quasi-one-dimensional dipolar spinor Bose-Einstein condensates in the homogeneous-local-spin-orientation approximation, that is with unidirectional local magnetization.…
Mesoscopics of half-quantum vortex pair deconfinement in a trapped spin-one condensate
Seong-Ho Shinn, Uwe R. Fischer
Motivated by a recent experiment in an antiferromagnetic spin-1 Bose-Einstein condensate of atoms, we study the energetical stability of a singly quantum vort…
