Journal ArticleDOI
Topological relics of symmetry breaking: Winding numbers and scaling tilts from random vortex-antivortex pairs
TL;DR: In this paper, it was shown that random distributions of vortex-antivortex pairs (rather than of individual vortices) lead to scaling of typical winding numbers W trapped inside a loop of circumference C with the square root of C when the expected winding numbers are large.

Decoherence and long-lived Schroedinger cats in BEC
TL;DR: In this paper, a decoherence rate for the Schrodinger cat is calculated and shown to be a significant threat to quantum superposition states in Bose-Einstein condensates.
Journal ArticleDOI
Causality and defect formation in the dynamics of an engineered quantum phase transition in a coupled binary Bose-Einstein condensate
TL;DR: Sabbatini et al. as discussed by the authors studied the effect of causality in the propagation of the phase transition front on the resulting formation of domain walls, and found indications that the density of defects is determined during the impulse to adiabatic transition after the crossing of the critical point.

Symmetry breaking bias in the dynamics of a quantum phase transition: a shortcut to adiabaticity?
TL;DR: In this article, the Kibble-Zurek mechanism predicts the formation of topological defects and other excitations that quantify how much a quantum system driven across a quantum critical point fails to be adiabatic.
