Reservoir-mediated spin entanglement in the mean-force Gibbs state
L. A. Williamson, W. McEniery, F. Cerisola +1
Two qubits strongly coupled to a common bosonic reservoir can become entangled with each other, despite having no direct interaction. In equilibrium, such coupling-induced coherenc…
Enhanced squeezing for quantum gravimetry in a Bose-Einstein condensate with focussing
Lewis A. Williamson, Karandeep Gill, Andrew J. Groszek +2
Free-fall atom interferometers offer a powerful platform for accurate, absolute gravitational sensing. Szigeti et al. [Phys. Rev. Lett. 125, 100402 (2020)] recently proposed a quan…
Frictional work and entropy production in integrable and non-integrable spin chains
Vishnu Muraleedharan Sajitha, Matthew J. Davis, L. A. Williamson
The maximum work extractable from a quantum system is achieved when the system is driven adiabatically. Frictional work then quantifies the differe…
Polar core vortex dynamics in disc-trapped homogeneous spin-1 Bose-Einstein condensates
Matthew Edmonds, Lewis A. Williamson, Matthew J. Davis
We study the dynamics of polar core vortices in the easy plane phase of an atomic spin-1 Bose-Einstein condensate confined in a two-dimensional disc potential. A single vortex move…
Quantum thermal machine regimes in the transverse-field Ising model
Vishnu Muraleedharan Sajitha, Bodhaditya Santra, Matthew J. Davis +1
We identify and interpret the possible quantum thermal machine regimes with a transverse-field Ising model as the working substance. In general, understanding the emergence of such…
