“…The initial expression for the force of the fluc tuation electromagnetic interaction between the par ticle and the plane has the form (1) where ρ and j are the local charge and electric current densities in the bulk of the particle, E and B are the vectors of the fluctuation electromagnetic field satisfy ing the Maxwell equations and necessary boundary conditions on the surface of the plate, and the angular brackets mean the total quantum statistical averaging.

“…In both cases, the atomic motion was taken into account by introducing the Doppler frequency shift for the polarizability of a moving particle, which is incorrect in the general case [9,10]. The aim of the present work is a consistent relativistic calculation of the dynamical Casimir-Polder force on the basis of the general theory of fluctuation electromagnetic interaction in the motion of a small particle near a sur face with allowance for the material properties, the delay effects, and the thermal state of the system [11]. Thus, this work naturally extends our recent calcula tions of the nonrelativistic van der Waals force [10].…”

The dynamical Casimir-Polder force between a neutral atom (in the ground state) and a thick plate in relativistic motion of the atom in the direction parallel to the surface has been calculated. The mate rial properties have been considered in the framework of the oscillator model of the atom and the Drude dielectric function for a plate. The limiting cases of the nonrelativistic velocity and perfectly conducting material of the plate have been discussed. A complex dependence of the force on the velocity (energy), the distance, and the material properties of the surface has been found.

“…For instance, when spatially separated objects are set in motion relative to each other, a fluctuation-induced drag force appears and counteracts the dynamics. This nonequilibrium scenario is usually referred to as quantum or Casimir friction [2][3][4][5][6][7][8]. The frictional interaction strongly depends on the optical response of the materials composing the objects in the system.…”

The dissipative properties of spatially nonlocal conductors are investigated in the context of quantum friction acting on an atom moving above a macroscopic body. The focus is on an extended version of the hydrodynamic model for the bulk material's electromagnetic response. It is shown that the standard hydrodynamic description is inadequate for evaluating the frictional force since it completely neglects Landau damping. The extended version of the model contains a frequencydependent compressibility factor for the Fermi liquid and qualitatively resolves this issue. For a quantitative assessment, these results are contrasted with those obtained for the more fundamental Boltzmann-Mermin model. Since the latter is technically involved, the simplicity of the extended hydrodynamic model allows for an easier analysis of the impact of nonlocality on quantum friction for other (planar) geometries. This is illustrated with an example involving a thin slab.

“…The second series includes the back action of quantum fields on the mirror, which is needed for treating mirror cooling (for earlier work see references in Ref. [54]); the results therein could be applied to the related topics of quantum friction [55][56][57][58] and vacuum viscosity [14,46,59]. A third series will focus on basic issues in quantum information, making use of the stochastic equations derived in a subsequent work for moving mirrors interacting with a quantum field, specifically on quantum decoherence, superposition, and entanglement of mirrors and field.…”

We present a microphysics model for the kinematics and dynamics of optomechanics describing the coupling between an optical field, modeled here by a massless scalar field, and the internal and mechanical degrees of freedom of a movable mirror. Instead of implementing boundary conditions on the field, we introduce an internal degree of freedom and its dynamics to describe the mirror's reflectivity. Depending on parameter values, the internal degrees of freedom of the mirror in this model capture a range of its optical activities, from those exhibiting broadband reflective properties to those reflecting only in a narrow band. After establishing the model we show how appropriate parameter choices lead to other well-known optomechanical models, As a simple illustrative application we derive classical radiation pressure cooling from this model. We then connect our microphysics model to the common descriptions of a moving mirror coupled to radiation pressure (e.g., with Nx coupling, where N is the photon number and x is the mirror displacement), making explicit the underlying assumptions made in these phenomenological models. Our model is also applicable to the lesser explored case of small N , which existing models based on sideband approximations [Kimble et al., Phys. Rev. D 65, 022002 (2001)] have not addressed. Interestingly, we also find that slow-moving mirrors in our model can be described by the ubiquitous Brownian motion model of quantum open systems. The scope of applications of this model ranges from a full quantum-mechanical treatment of radiation pressure cooling and quantum entanglement between macroscopic mirrors to the back reaction of Hawking radiation on black-hole evaporation in a moving mirror analog.
