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 …

The contribution of vacuum fluctuations and the radiation reaction to the energy-level shifts
of a hydrogen atom, moving with uniform acceleration and interacting with the …

The retarded van der Waals forces between neutral molecules in their ground states is
obtained by a conceptually simple route. Vacuum fluctuations of the electromagnetic field …

We consider a multilevel hydrogen atom in interaction with the quantum electromagnetic
field and separately calculate the contributions of the vacuum fluctuation and radiation …

We investigate the radiative processes of a quantum system composed by two identical two-
level atoms in the de Sitter spacetime, interacting with a conformally coupled massless …

In this paper, we have investigated the influence of the counter-rotating terms on the
squeezing of light in the two-photon Jaynes-Cummings model by means of the …

We study a two-level atom in interaction with a real massless scalar quantum field in a
spacetime with a reflecting boundary. The presence of the boundary modifies the quantum …

We study, in the multipolar coupling scheme, a uniformly accelerated multilevel hydrogen
atom in interaction with the quantum electromagnetic field near a conducting boundary and …

We study the average rate of change of energy for a static atom immersed in a thermal bath
of electromagnetic radiation in the cosmic string spacetime and separately calculate the …

A spinless, nonrelativistic hydrogen atom coupled to an electromagnetic field is considered.
The interaction is taken in the minimal-coupling form, and the ground state of the coupled …
