Adaptive numerical algorithms to simulate the dynamical Casimir effect in a closed cavity with different boundary conditions
(American Physical Society, 2017-07)
We present an alternative numerical approach to compute the number of particles created inside a cavity due to time-dependent boundary conditions. The physical model consists of a rectangular cavity, where a wall always ...
Photon generation via the dynamical Casimir effect in an optomechanical cavity as a closed quantum system
(American Physical Society, 2019-12-30)
We present an analytical and numerical analysis of the particle creation in an optomechanical cavity in parametric resonance. We treat both the electromagnetic field and the mirror as quantum degrees of freedom and study ...
O efeito Casimir dinâmico e decoerência
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2008-07-03)
In this thesis we first demonstrate that the inevitable action of the environment can be substantially weakened when considering appropriate nonstationary quantum systems. Beyond protecting quantum states against decoherence, ...
Action of the gravitational field on the dynamical Casimir effect
(IOP PUBLISHING LTD, 2009)
In this paper, we analyze the action of the gravitational field on the dynamical Casimir effect. We consider a massless scalar field confined in a cuboid cavity placed in a gravitational field described by a static and ...
Dynamical Casimir effect for a massless scalar field between two concentric spherical shells
(AMER PHYSICAL SOC, 2008)
In this work we consider the dynamical Casimir effect for a massless scalar field-under Dirichlet boundary conditions-between two concentric spherical shells. We obtain a general expression for the average number of particle ...
Closed-time-path approach to the Casimir energy in real media
(American Physical Society, 2014-05)
The closed-time-path (CTP) formalism is applied, in the framework of open quantum systems, to study the time evolution of the expectation value of the energy-momentum tensor of a scalar field in the presence of real ...
Casimir effect for the scalar field under Robin boundary conditions: a functional integral approach
(Iop Publishing Ltd, 2004-07-09)
In this work we show how to define the action of a scalar field such that the Robin boundary condition is implemented dynamically, i.e. as a consequence of the stationary action principle. We discuss the quantization of ...

Dynamical Casimir effect via modulated Kerr or higher-order nonlinearities

Motion-induced radiation due to an atom in the presence of a graphene plane
(MDPI AG, 2021-05)
We study the motion-induced radiation due to the non-relativistic motion of an atom, coupled to the vacuum electromagnetic field by an electric dipole term, in the presence of a static graphene plate. After computing the ...
