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…
Measuring work and heat in ultracold quantum gases
G. De Chiara, A. J. Roncaglia, J. P. Paz
We propose a feasible experimental scheme to direct measure heat and work in cold atomic setups. The method is based on a recent proposal which shows that work is a positive operat…
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…
Tunable Polarons in Bose-Einstein Condensates
E. Compagno, G. De Chiara, D. G. Angelakis +1
A toolbox for the quantum simulation of polarons in ultracold atoms is presented. Motivated by the impressive experimental advances in the area of ultracold atomic mixtures, we the…
Shortcut to Adiabaticity in the Lipkin-Meshkov-Glick Model
Steve Campbell, Gabriele De Chiara, Mauro Paternostro +2
We study transitionless quantum driving in an infinite-range many-body system described by the Lipkin-Meshkov-Glick model. Despite the correlation length being always infinite the…
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…
Characterization of Bose-Hubbard Models with Quantum Non-demolition Measurements
B. Rogers, M. Paternostro, J. F. Sherson +1
We propose a scheme for the detection of quantum phase transitions in the 1D Bose-Hubbard (BH) and 1D Extended Bose-Hubbard (EBH) models, using the non-demolition measurement techn…
Low-energy behaviour of strongly-interacting bosons on a flat-banded lattice above the critical filling factor
Lawrence G. Phillips, Gabriele De Chiara, Patrik Öhberg +1
Bosons interacting repulsively on a lattice with a flat lowest band energy dispersion may, at sufficiently small filling factors, enter into a Wigner-crystal-like phase. This phase…
Cavity-aided quantum parameter estimation in a bosonic double-well Josephson junction
M. Zuppardo, J. P. Santos, G. De Chiara +3
We describe an apparatus designed to make non-demolition measurements on a Bose-Einstein condensate (BEC) trapped in a double-well optical cavity. This apparatus contains, as well…
Assessing the non-equilibrium thermodynamics in a quenched quantum many-body system via single projective measurements
L. Fusco, S. Pigeon, T. J. G. Apollaro +6
We analyse the nature of the statistics of the work done on or by a quantum many-body system brought out of equilibrium. We show that, for the sudden quench and for an initial stat…
Out of equilibrium thermodynamics of quantum harmonic chains
A. Carlisle, L. Mazzola, M. Campisi +7
The thermodynamic implications for the out-of-equilibrium dynamics of quantum systems are to date largely unexplored, especially for quantum many-body systems. In this paper we inv…
Hybrid optomechanics for Quantum Technologies
Benjamin Rogers, Nicola Lo Gullo, Gabriele De Chiara +2
We review the physics of hybrid optomechanical systems consisting of a mechanical oscillator interacting with both a radiation mode and an additional matter-like system. We concent…
Detecting the work statistics through Ramsey-like interferometry
Laura Mazzola, Gabriele De Chiara, Mauro Paternostro
Out-of-equilibrium statistical mechanics is attracting considerable interest due to the recent advances in the control and manipulations of systems at the quantum level. Recently,…
