Calibrated quantum thermometry in cavity optomechanics

A Chowdhury, P Vezio, M Bonaldi +9

Cavity optomechanics has achieved the major breakthrough of the preparation and observation of macroscopic mechanical oscillators in peculiarly quantum states. The development of r…

Quantum spin systems versus Schroedinger operators: A case study in spontaneous symmetry breaking

C. J. F. van de Ven, G. C. Groenenboom, R. Reuvers +1

Spontaneous symmetry breaking (SSB) is mathematically tied to some limit, but must physically occur, approximately, before the limit. Approximate SSB has been independently underst…

Mechanical back-reaction effect of the dynamical Casimir emission

Salvatore Butera, Iacopo Carusotto

We consider an optical cavity enclosed by a freely moving mirror attached to a spring and we study the quantum friction effect exerted by the dynamical Casimir emission on the mech…

Quantum Annealing Learning Search for solving QUBO problems

Enrico Blanzieri, Davide Pastorello

In this paper we present a novel strategy to solve optimization problems within a hybrid quantum-classical scheme based on quantum annealing, with a particular focus on QUBO proble…

Quantum reverse hypercontractivity: its tensorization and application to strong converses

Salman Beigi, Nilanjana Datta, Cambyse Rouzé

In this paper we develop the theory of quantum reverse hypercontractivity inequalities and show how they can be derived from log-Sobolev inequalities. Next we prove a generalizatio…

Localisation Transition in the Driven Aubry-André Model

Donato Romito, Carlos Lobo, Alessio Recati

A recent experiment by P. Bordia et al. (Periodically Driving a Many Body Localized Quantum System, Nat Phys, Jan 2017) has demonstrated that periodically modulating the potential…

Dynamics of multiple atoms in one-dimensional fields

Carlo Cascio, Jad C. Halimeh, Ian P. McCulloch +2

We analyze the dynamics of a set of two-level atoms coupled to the electromagnetic environment within a waveguide. This problem is often tackled by assuming a weak coupling between…
