• Abstract: We demonstrate a simple technique for adding controlled dissipation to Rydberg atom experiments. In our experiments we excite cold rubidium atoms in a magneto-optical trap to $70$-S Rydberg states, whilst simultaneously inducing forced dissipation by resonantly coupling the Rydberg state to a hyperfine level of the short-lived $6$-P state. The resulting effective dissipation can be varied in strength and switched on and off during a single experimental cycle.

  We show theoretically that it is possible to transfer vibrational excitation between trapped neutral atoms over a micrometer apart. We find that there is a "sweet spot" where the transfer of a vibrational excitation is nearly perfect and fast compared to the Rydberg lifetime.

  Atoms excited to electronically high-lying Rydberg states decay to low-energy states through spontaneous emission processes. We report experimental observations of a significant slowdown in superradiance upon applying an electric field. Our numerical simulations demonstrate that superradiance decoherence is caused by the Stark shifts of the Rydberg level.

  We consider ultralong-range polyatomic Rydberg molecules formed by combining a Rydberg cesium atom and a ground-state RbCs molecule. We explore the regime where the charge-dipole interaction due to the Rydberg electron with the diatomic polar molecule couples the quantum defect Rydberg states Cs(ns) to the nearest hydrogenic manifold.

• Facilitation of controllable excitation in Rydberg atomic ensembles [0.0]
  We show that a control atom's excitation adds to a second two-photon transition onto the doubly-excited Rydberg state, arising an excitation facilitation for the ensemble atoms. Results can provide a flexible control for the excitation of Rydberg atomic ensembles and participate further uses in developing mesoscopic Rydberg gates.
