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 …

Quantum electrodynamics (QED) is the physical theory that describes the interaction of
electrons and photons at a fundamental level. Its characteristic feature is that the radiation …

We consider the Casimir-Polder interaction between two atoms, one in the ground state and
the other in its excited state. The interaction is time dependent for this system, because of the …

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 …

We develop a dynamical approach to study the Casimir-Polder force between an initially
bare molecule and a magnetodielectric body at finite temperature, valid for arbitrary …

In a previous paper we have studied dressed excited states in the Friedrichs model, which
describes a two-level atom interacting with radiation. In our approach, excited states are …

Quantum electrodynamics (QED) is the fundamental theory describing the interaction of
electrons and photons. Its characteristic feature is that both radiation and matter are treated …

A toolbox for the quantum simulation of polarons in ultracold atoms is presented. Motivated
by the impressive experimental advances in the area of ultracold atomic mixtures, we …

We consider a pair of identical two-level atoms interacting with a scalar field in one
dimension, separated by a distance x 21. We obtain collective decaying states, belonging to …

A method previously introduced to evaluate the far zone part (Casimir-Polder) of the non-
additive van der Waals interaction between three ground-state isotropic non-overlapping …
