Field observables near a fluctuating boundary
Federico Armata, Salvatore Butera, Federico Montalbano +2
We review several aspects related to the confinement of a massless scalar field in a cavity with a movable conducting wall of finite mass, free to move around its equilibrium posit…
Spatial correlations of field observables in two half-spaces separated by a movable perfect mirror
Federico Montalbano, Federico Armata, Lucia Rizzuto +1
We consider a system of two cavities separated by a reflecting boundary of finite mass that is free to move, and bounded to its equilibrium position by a harmonic potential. This y…
Optical squeezing for an optomechanical system without quantising the mechanical motion
Yue Ma, Federico Armata, Kiran E. Khosla +1
Witnessing quantumness in mesoscopic objects is an important milestone for both quantum technologies and foundational reasons. Cavity optomechanics offers the ideal system to achie…
Nonequilibrium dressing in a cavity with a movable reflecting mirror
Federico Armata, M. S. Kim, Salvatore Butera +2
We consider a movable mirror coupled to a one-dimensional massless scalar field in a cavity. Both the field and the mirror's mechanical degrees of freedom are described quantum-mec…
Quantum limits to gravity estimation with optomechanics
Federico Armata, Ludovico Latmiral, A. D. K Plato +1
We present a table-top quantum estimation protocol to measure the gravitational acceleration by using an optomechanical cavity. In particular, we exploit the non-linear quantum…
Effect of boundaries on vacuum field fluctuations and radiation-mediated interactions between atoms
F. Armata, S. Butera, G. Fiscelli +6
In this paper we discuss and review several aspects of the effect of boundary conditions and structured environments on dispersion and resonance interactions involving atoms or mol…
Dynamical Casimir-Polder force between an excited atom and a conducting wall
Federico Armata, Ruggero Vasile, Pablo Barcellona +3
We consider the dynamical atom-surface Casimir-Polder force in the non-equilibrium configuration of an atom near a perfectly conducting wall, initially prepared in an excited state…
Quantum and Classical Phases in Optomechanics
Federico Armata, Ludovico Latmiral, Igor Pikovski +3
The control of quantum systems requires the ability to change and read-out the phase of a system. The non-commutativity of canonical conjugate operators can induce phases on quantu…
Probing anharmonicity of a quantum oscillator in an optomechanical cavity
Ludovico Latmiral, Federico Armata, Marco G. Genoni +2
We present a way of measuring with high precision the anharmonicity of a quantum oscillator coupled to an optical field via radiation pressure. Our protocol uses a sequence of puls…
Vacuum energy densities of a field in a cavity with a mobile boundary
Federico Armata, Roberto Passante
We consider the zero-point field fluctuations, and the related field energy densities, inside a one-dimensional and a three-dimensional cavity with a mobile wall. The mechanical de…
