Abstract summary: We analyze the influence of a massive photon in the dispersive interaction between two atoms in their fundamental states. The photon mass not only introduces a new length scale but also gives rise to a longitudinal polarization for the electromagnetic field.

Abstract: We analyze the influence of a massive photon in the dispersive interaction between two atoms in their fundamental states. We work in the context of Proca Quantum Electrodynamics. The photon mass not only introduces a new length scale but also gives rise to a longitudinal polarization for the electromagnetic field. We obtain explicitly the interaction energy between the atoms for any distance regime and consider several particular cases. We show that, for a given interatomic distance, the greater the photon mass the better it is the non-retarded approximation.

Quantum decoherence of free electrons and interaction with distant objects [0.0]
macroscopic correlations involving macroscopic distances can be observed between entangled photons as well as in atomic gases and matter waves at low temperatures. We reveal a manifestation of quantum mechanics that involves macroscopic distances and results in a nearly complete depletion of coherence. Our results suggest an approach to measuring the vacuum temperature and nondestructively sensing the presence of distant objects.

Mirror-mediated ultralong-range atomic dipole-dipole interactions [0.0]
We show that it is possible to significantly extend the range of dipole-dipole interactions with the help of a partially transparent asymmetric mirror interface. Although the resulting ultralong-range interactions are in general relatively weak, we expect them to find applications in quantum technology.

Bound state of distant photons in waveguide quantum electrodynamics [137.6408511310322]
Quantum correlations between distant particles remain enigmatic since the birth of quantum mechanics. We predict a novel kind of bound quantum state in the simplest one-dimensional setup of two interacting particles in a box. Such states could be realized in the waveguide quantum electrodynamics platform.

We study the electronic and ro-vibrational states of heavy homonuclear lanthanide Er2 and Tm2 molecules by applying state-of-the-art relativistic methods. We were able to obtain reliable spin-orbit and correlation-induced splittings between the 91 Er2 and 36 Tm2 electronic potentials dissociating to two ground-state atoms.

Universal pair-polaritons in a strongly interacting Fermi gas [0.0]
We report on experiments using molecular transitions in a strongly interacting Fermi gas, directly coupling cavity photons to pairs of atoms. The dependence of the pair-polariton spectrum on interatomic interactions is universal, independent of the transition used. This represents a magnification of many-body effects by two orders of magnitude in energy.

Exotic photonic molecules via Lennard-Jones-like potentials [48.7576911714538]
We show a novel Lennard-Jones-like potential between photons coupled to the Rydberg states via electromagnetically induced transparency (EIT) This potential is achieved by tuning Rydberg states to a F"orster resonance with other Rydberg states. For a few-body problem, the multi-body interactions have a significant impact on the geometry of the molecular ground state.
