Entropic entanglement criteria in phase space
Stefan Floerchinger, Martin Gärttner, Tobias Haas +1
We derive entropic inseparability criteria for the phase space representation of quantum states. In contrast to criteria involving differential entropies of marginal phase space di…
Dynamical mechanisms of vortex pinning in superfluid thin films
Oliver R. Stockdale, Matthew T. Reeves, Matthew J. Davis
We characterize the mechanisms of vortex pinning in a superfluid thin film described by the two-dimensional Gross-Pitaevskii equation. We consider a vortex "scattering experiment"…
Turbulent relaxation to equilibrium in a two-dimensional quantum vortex gas
Matthew T. Reeves, Kwan Goddard-Lee, Guillaume Gauthier +9
We experimentally study emergence of microcanonical equilibrium states in the turbulent relaxation dynamics of a two-dimensional chiral vortex gas. Same-sign vortices are injected…
Coherent vortex dynamics in a strongly-interacting superfluid on a silicon chip
Yauhen P. Sachkou, Christopher G. Baker, Glen I. Harris +8
Two-dimensional superfluidity and quantum turbulence are directly connected to the microscopic dynamics of quantized vortices. However, surface effects have prevented direct observ…
