- Abstract: A gauge field treatment of a current, oscillating at a fixed frequency, of
interacting neutral atoms leads to a set of matter-wave duals to Maxwell's
equations for the electromagnetic field. In contrast to electromagnetics, the
velocity of propagation has a lower limit rather than upper limit and the wave
impedance of otherwise free space is negative real-valued rather than 377 Ohms.
Quantization of the field leads to the matteron, the gauge boson dual to the
photon. Unlike the photon, the matteron is bound to an atom and carries
negative rather than positive energy, causing the source of the current to
undergo cooling. Eigenstates of the combined matter and gauge field
annihilation operator define the coherent state of the matter-wave field, which
exhibits classical coherence in the limit of large excitation.

We focus on bound states in the continuum, occurring in correspondence of excitation energies in which a single excited emitter would decay.
We discuss the emergence of multimers, consisting in subsets of emitters separated by two lattice spacings in which the electromagnetic field is approximately vanishing.

We investigate the effects of noncommutative Quantum Mechanics in three dimensions on the energy levels of a charged isotropic harmonic oscillator in the presence of a uniform magnetic field in the z-direction.
The most important result we can note is that all energy corrections due to noncommutativity are negative and their magnitude increase with increasing Quantum numbers and magnetic field.

The entanglement harvesting protocol is an operational way to probe vacuum entanglement.
Using this protocol, it is demonstrated that while the transition probability of an individual atom is unaffected by the presence of a gravitational wave, the entanglement harvested by two atoms depends sensitively on the frequency of the gravitational wave.
This suggests that the entanglement signature left by a gravitational wave may be useful in characterizing its properties, and potentially useful in exploring the gravitational-wave memory effect and gravitational-wave induced decoherence.
