Probing anharmonicity of a quantum oscillator in an optomechanical cavity
TL;DR: In this paper, a method for measuring the anharmonicity of a quantum oscillator coupled to an optical field via radiation pressure is presented, where a sequence of pulsed interactions are used to perform a loop in the phase space of the mechanical oscillator, which is prepared in a thermal state.
Dynamical Casimir-Polder force between an excited atom and a conducting wall
Federico Armata,Ruggero Vasile,Pablo Barcellona,Stefan Yoshi Buhmann,Lucia Rizzuto,Roberto Passante +5 more
TL;DR: In this article, the dynamical atom-surface Casimir-Polder force in the nonequilibrium configuration of an atom near a perfectly conducting wall, initially prepared in an excited state with the field in its vacuum state, was investigated.

Optical squeezing for an optomechanical system without quantizing the mechanical motion
Yue Ma,Federico Armata,Kiran E. Khosla,Myungshik Kim +3 more
- 21 May 2020
TL;DR: In this article, the need to quantize the mechanical motion of an optomechanical system based solely on homodyne measurements of the optical field was investigated, and it was shown that optical squeezing alone cannot witness the quantum nature of the mechanical oscillator.
Berry-Hannay relation in nonlinear optomechanics.
TL;DR: This work addresses the quantum-classical comparison of phase measurements in optomechanics in the general framework of Berry phases for composite systems and recovers the aforementioned mathematical relation with the Hannay angle obtained from classical equations of motion.
Effect of boundaries on vacuum field fluctuations and radiation-mediated interactions between atoms
Federico Armata,Salvatore Butera,Giuseppe Fiscelli,R. Incardone,R. Incardone,Valentina Notararigo,R. Palacino,Roberto Passante,Lucia Rizzuto,Salvatore Spagnolo +9 more
TL;DR: In this paper, the effect of boundary conditions and structured environments on dispersion and resonance interactions involving atoms or molecules, as well as on vacuum field fluctuations, is discussed and discussed and reviewed.
