Dynamical Casimir-Polder force on a partially dressed atom near a conducting wall

Riccardo Messina, Ruggero Vasile, Roberto Passante

We study the time evolution of the Casimir-Polder force acting on a neutral atom in front of a perfectly conducting plate, when the system starts its unitary evolution from a partially dressed state. We solve the Heisenberg equations for both atomic and field quantum operators, exploiting a series expansion with respect to the electric charge and an iterative technique. After discussing the behavior of the time-dependent force on an initially partially dressed atom, we analyze a possible experimental scheme to prepare the partially dressed state and the observability of this new dynamical effect.

Synthetic electric and magnetic fields for ultracold neutral atoms

William D. Phillips, Y-J Lin, R. L. Compton +4 more

We use Raman coupling between magnetic sublevels of a 87 Rb BEC to create an effective vector gauge field for the neutral atoms. They behave as if they were charged particles in a magnetic vector potential. With appropriate spatial gradients and time derivatives of this vector potential we produce synthetic magnetic and electric fields for the atoms. This paper is a brief summary of the presentation made by the first author at ICAP 2010 in Cairns, Australia. It is not intended as a complete report on the research described, nor does it attempt to be a fully referenced documentation of that research and the relevant literature. Here, we provide references to the published work where a more complete description and more complete references to related literature may be found.

Dipole condensates in synthetic rank-2 electric fields

Anonymous, Wenhui Xu, Qi Zhou +1 more

Dipole condensates, formed from particle-hole pairs, represent a unique class of charge-neutral quantum fluids that evade conventional vector gauge fields, making their electrodynamic responses difficult to probe in natural materials. Here, we propose a tunable platform using strongly interacting two-component ultracold atoms to realize dipole condensates and probe their coupling to rank-2 electric fields. By applying spin-dependent forces and treating spin as a synthetic dimension, we engineer a synthetic rank-2 electric field that induces measurable electrodynamic responses. We identify the atomic analog of perfect Coulomb drag: increasing intercomponent interactions leads to equal and opposite displacements of the centers of mass of the two spin components. Furthermore, a rank-2 electric field imprints a phase twist in the dipole condensate and generates a supercurrent of dipoles that obeys the dipolar Josephson relation -- a smoking gun for dipole condensation. Our results establish a powerful platform for exploring dipolar superfluidity under tensor gauge fields.
