We report on the quantum electrodynamical analog of a Sagnac phase induced by the fast rotation of a neutral nanoparticle onto atomic waves propagating in its vicinity. The quantum vacuum Sagnac phase is a geometric Berry phase proportional to the angular velocity of rotation. The persistence of a noninertial effect into the inertial frame is also analogous to the Aharonov-Bohm effect. Here, a rotation confined to a restricted domain of space gives rise to an atomic phase even though the…

Non-local double-path Casimir phase in atom interferometers
We present an open quantum system theory of atom interferometers evolving in the quantized electromagnetic field bounded by an ideal conductor. Our treatment reveals an unprecedented feature of
Shaping Dynamical Casimir Photons
Temporal modulation of the quantum vacuum through fast motion of a neutral body or fast changes of its optical properties is known to promote virtual into real photons, the so-called dynamical
Non-additive dynamical Casimir atomic phases
We discuss a fundamental property of open quantum systems: the quantum phases associated with their dynamical evolution are non-additive. We develop our argument by considering a multiple-path atom
Quantum interference of currents in an atomtronic SQUID
The authors demonstrate quantum interference of currents in the atomtronic analog of a SQUID using Bose-Einstein condensates of 87 Rb atoms to show the possibility of studying various interesting SQUID physics with anatomtronic SQUID and especially, macroscopic quantum phenomena with currents may be realized with an atomtronics SQUID toward the goal of quantum metrology of rotation sensing.
Shaking photons from the vacuum: acceleration radiation from vibrating atoms
Acceleration radiation—or Unruh radiation—the thermal radiation observed by an ever accelerating observer or detector, although having similarities to Hawking radiation, so far has proved extremely
Towards detecting traces of non-contact quantum friction in the corrections of the accumulated geometric phase
The geometric phase can be used as a fruitful venue of investigation to infer features of the quantum systems. Its application can reach new theoretical frontiers and imply innovative and challenging
Motion-Induced Radiation Due to an Atom in the Presence of a Graphene Plane
We study the motion-induced radiation due to the non-relativistic motion of an atom, coupled to the vacuum electromagnetic field by an electric dipole term, in the presence of a static graphene
Detectable Signature of Quantum Friction on a Sliding Particle in Vacuum
Spatially separated bodies in a relative motion through vacuum experience a tiny friction force known as quantum friction (QF). This force has so far eluded experimental detection due to its small
The Quantum Radiation from Mirrors Moving Sideways
We calculate the radiation (of scalar “photon” pairs) by a halfspace oscillating harmonically and rigidly with speed v = v 0 cos(Ωt), where v 0/c ≪ 1. As shown earlier [1], a treatment by standard

A quantal system in an eigenstate, slowly transported round a circuit C by varying parameters R in its Hamiltonian Ĥ(R), will acquire a geometrical phase factor exp{iγ(C)} in addition to the familiar
