A "squeezed polaron" variational wavefunction for the spin boson model
Diego Barberena, Nigel Cooper
The localization transition of the sub-Ohmic spin-boson model generates boson bath correlations that are, at low frequencies, analytically inaccessible to standard coherent-state-p…

Observation of Vinen turbulence during far-from-equilibrium Bose-Einstein condensation
Sebastian J. Morris, Martin Gazo, Simon M. Fischer +5
Relaxation of far-from-equilibrium quantum fluids, intimately related to the emergence of long-range order, is theoretically associated with the decay of a turbulent isotropic tang…

Strong Correlations in the Dynamical Evolution of Lowest Landau Level Bosons
Yuchen Yang, Nigel R. Cooper
Recent experiments with rotating Bose gases have demonstrated the interaction-driven hydrodynamic instability of an initial extended strip-like state in the lowest Landau level. We…
