Dispersion interactions between neutral atoms and the quantum electrodynamical vacuum

R Passante - Symmetry, 2018 - mdpi.com
Dispersion interactions are long-range interactions between neutral ground-state atoms or
molecules, or polarizable bodies in general, due to their common interaction with the …

Field fluctuations in a one-dimensional cavity with a mobile wall

S Butera, R Passante - Physical Review Letters, 2013 - APS
We consider a scalar field in a one-dimensional cavity with a mobile wall. The wall is
assumed bounded by a harmonic potential and its mechanical degrees of freedom are …

Spatial correlations of field observables in two half-spaces separated by a movable perfect mirror

F Montalbano, F Armata, L Rizzuto, R Passante - Physical Review D, 2023 - APS
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 yields an …

Vacuum energy densities of a field in a cavity with a mobile boundary

F Armata, R Passante - Physical Review D, 2015 - APS
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 …

Probing quantum vacuum fluctuations over a charged particle near a reflecting wall

VA De Lorenci, CCH Ribeiro, MM Silva - Physical Review D, 2016 - APS
We investigate the influence of the vacuum fluctuations of a background electric field over a
charged test particle in the presence of a perfectly reflecting flat wall. A switching function …

Resonance interaction energy between two entangled atoms in a photonic bandgap environment

V Notararigo, R Passante, L Rizzuto - Scientific reports, 2018 - nature.com
We consider the resonance interaction energy between two identical entangled atoms,
where one is in the excited state and the other in the ground state. They interact with the …

Dynamical Casimir-Polder interaction between an atom and surface plasmons

HR Haakh, C Henkel, S Spagnolo, L Rizzuto… - Physical Review A, 2014 - APS
We investigate the time-dependent Casimir-Polder potential of a polarizable two-level atom
placed near a surface of arbitrary material, after a sudden change in the parameters of the …

Casimir effect for scalar current densities in topologically nontrivial spaces

S Bellucci, AA Saharian, NA Saharyan - The European Physical Journal C, 2015 - Springer
We evaluate the Hadamard function and the vacuum expectation value (VEV) of the current
density for a charged scalar field, induced by flat boundaries in spacetimes with an arbitrary …

Dynamical Casimir-Polder force between an excited atom and a conducting wall

F Armata, R Vasile, P Barcellona, SY Buhmann… - Physical Review A, 2016 - APS
We consider the dynamical atom-surface Casimir-Polder force in the nonequilibrium
configuration of an atom near a perfectly conducting wall, initially prepared in an excited …

Vacuum Casimir energy densities and field divergences at boundaries

N Bartolo, S Butera, M Lattuca… - Journal of Physics …, 2015 - iopscience.iop.org
We consider and review the emergence of singular field fluctuations or energy densities at
sharp boundaries or point-like field sources in the vacuum. The presence of singular energy …
