Decoherence of Rydberg molecules — •Andrew Hunter, Alex Eisfeld, and Jan-Micheal Rost — Max Planck Institute for the Physics of Complex Systems

A Rydberg atom in the presence of a neutral perturber is investigated using scattering theory. Due to a negative s-wave scattering length at low energies these perturbers can form a bound state with the Rydberg atom, known as a trilobite molecule [1]. These molecules interact strongly with their environment due to their large polarisability or dipole moment [2]. In particular, we study such systems coupled to external environments and the decoherence that results. The prospect of interfacing these molecules with mesoscopic systems such as a moving mirror is then explored.
