When atomic gases are laser driven to Rydberg states in an off resonant way, a single Rydberg atom may enhance the excitation rate of surrounding atoms. This leads to a facilitated excitation referred to as Rydberg anti-blockade. In the usual facilitation scenario, the detuning of the laser from resonance compensates the interaction shift. Here, we discuss a different excitation mechanism, which we call anomalous facilitation. This occurs on the "wrong side" of the resonance and originates from…

Motion assisted facilitated excitation of Rydberg atoms in optical tweezers

Rydberg atoms feature extremely strong interactions, in particular between states of opposite electronic parity. In a room temperature environment, these states are inevitably populated due to

Deterministic facilitated excitation of the weakly driven atom in heteronuclear Rydberg atom pairs beyond antiblockade

Due to the intrinsic strong blockaded interaction shifting the energy level of the Rydberg state, the steady Rydberg probability may be substantially restrained to a low level, especially for atoms

Rydberg interaction induced enhanced excitation in thermal atomic vapor

A good agreement is found between the experimental observations and the proposed interacting model and this result implies possible applications towards quantum logic gates using Rydberg anti-blockade in thermal atomic vapor.

Distinct antiblockade features of strongly interacting Rydberg atoms under a two-color weak excitation scheme

We present distinct antiblockade features of strongly interacting 64D5/2 Rydberg atoms employing a two-color excitation scheme. The first color (pulse A) is set to resonantly excite a few seed

Spontaneous avalanche dephasing in large Rydberg ensembles

Strong dipole-exchange interactions due to spontaneously produced contaminant states can trigger rapid dephasing in many-body Rydberg ensembles [E. Goldschmidt et al., PRL 116, 113001 (2016)]. Such

Realization of Rydberg-dressed quantum magnets

Interacting ultracold atomic quantum gases provide an ideal test bed to study strongly correlated quantum matter. The interactions between atoms in such an ultracold quantum gas are typically

Dissipation-induced dipole blockade and antiblockade in driven Rydberg systems

We study theoretically and experimentally the competing blockade and anti-blockade effects induced by spontaneously generated contaminant Rydberg atoms in driven Rydberg systems. These contaminant

Finite-size scaling of the photon-blockade breakdown dissipative quantum phase transition

We prove that the observable telegraph signal accompanying the bistability in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings model is the finite-size precursor of what
