Heat transport in harmonic oscillator systems with correlated baths: Application to optomechanical arrays
André Xuereb, Alberto Imparato, Aurélien Dantan
We investigate the transport of phonons between harmonic oscillators in contact with independent thermal baths and coupled to a common oscillator, and derive an expression for…
Out-of-equilibrium Thermodynamics of Quantum Optomechanical Systems
M. Brunelli, A. Xuereb, A. Ferraro +3
We address the out-of-equilibrium thermodynamics of an isolated quantum system consisting of a cavity optomechanical device. We explore the dynamical response of the system when dr…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
Thermodynamics of trajectories of a quantum harmonic oscillator coupled to baths
Simon Pigeon, Lorenzo Fusco, André Xuereb +2
We undertake a thorough analysis of the thermodynamics of the trajectories followed by a quantum harmonic oscillator coupled to dissipative baths by using a new approach to lar…
Dynamical symmetries and crossovers in a three-spin system with collective dissipation
Simon Pigeon, André Xuereb, Igor Lesanovsky +3
We consider the non-equilibrium dynamics of a simple system consisting of interacting spin- particles subjected to a collective damping. The model is close to situations that…
Macroscopicity in an optomechanical matter-wave interferometer
André Xuereb, Hendrik Ulbricht, Mauro Paternostro
We analyse a proposal that we have recently put forward for an interface between matter-wave and optomechanical technologies from the perspective of macroscopic quantumness. In par…
