An atom, coupled linearly to an environment, is considered in a harmonic approximation in thermal equilibrium inside a cavity. The environment is modeled by an infinite set of harmonic oscillators. We employ the notion of dressed states to investigate the time evolution of the atom initially in the first excited level. In a very large cavity (free space) for a long elapsed time, the atom decays and the value of its occupation number is the physically expected one at a given temperature. For a…

Spontaneous Decay of a Dressed Harmonic Oscillator Inside a Spherical Cavity

We consider a complete study of the influence of the cavity size on the spontaneous decay of an atom excited state, roughly approximated by a harmonic oscillator. We confine the oscillator-field

Time evolution of entangled biatomic states in a cavity

We study the time evolution of entangled states of a pair of identical atoms, considered in the harmonic approximation, coupled to an environment represented by an infinite set of free oscillators,

Uncertainty principle in a cavity at finite temperature

We employ a dressed state approach to perform a study on the behavior of the uncertainty principle for a system in a heated cavity. We find, in a small cavity for a given temperature, an oscillatory



Renormalized coordinate approach to the thermalization process

We consider a particle in the harmonic approximation coupled linearly to an environment modeled by an infinite set of harmonic oscillators. The system (particle environment) is considered in a cavity

Cooling to the ground state of axial motion for one atom strongly coupled to an optical cavity.

It is found that the lowest vibrational level of the axial potential with zero-point energy variant Planck's over 2 h omega a/2kB = 13 microK is occupied with probability P0 approximately 0.95.

Time evolution of a superposition of dressed oscillator states in a cavity

Using the formalism of renormalized coordinates and dressed states introduced in previous publications, we perform a nonperturbative study of the time evolution of a superposition of two states, the

Spontaneous emission of an atom near a wedge

It is a well known fact that the presence of material bodies in the vicinity of an atom affects its interaction with the always present quantized electromagnetic field. In this paper, we focus on how

Stability of excited atoms in small cavities

We consider a system consisting of an atom in the approximation of a harmonic oscillator of frequency $\overline{\ensuremath{\omega}},$ coupled to the scalar potential inside a spherical reflecting

Atom–wall dispersive forces from the master equation formalism

Using the general expressions for level shifts obtained from the master equation for a small system interacting with a large one considered as a reservoir, we calculate the dispersive potentials

Trapping an atom with single photons

High-finesse optical cavity experiments in which the change in transmission induced by a single slow atom approaching the cavity triggers an external feedback switch which traps the atom in a light field containing about one photon on average, should facilitate investigations of the dynamics of single quantum objects and may find future applications in quantum information processing.

An exact approach to the oscillator radiation process in an arbitrarily large cavity

Starting from a solution of the problem of a mechanical oscillator coupled to a scalar field inside a reflecting sphere of radius R, we study the behaviour of the system in free space as the limit of

The inhibition of spontaneous emission from an atom inside a cavity and a laser spectroscopic measurement of the van der Waals interaction between a single Rydberg atom and a gold cavity showed that a simple electrostatic model of the atom–cavity interaction is correct when the cavity is small enough.
