We observe and characterize intrinsic optical bistability in a dilute Rydberg vapor. The bistability is characterized by sharp jumps between states of low and high Rydberg occupancy with jump-up and -down positions displaying hysteresis depending on the direction in which the control parameter is changed. We find that the shift in frequency of the jump point scales with the fourth power of the principal quantum number. Also, the width of the hysteresis window increases with increasing principal…

Intrinsic Rydberg Optical Bistability
Alkali metal atomic vapours excited to high lying Rydberg states exhibit intrinsic optical bistability which has been the subject of several recent studies [1, 2, 3, 4]. In this chapter we explore
Controlled bistability of cold Rydberg excitation with Doppler broadening
We study in theory the single-photon Rydberg excitation in an ensemble of two-level cold atoms at finite low temperatures. Rydberg population plotted against laser detuning may exhibit a nonlinear
Stochastic switching in the Rydberg atomic ensemble.
Stochastic switching in a bistable system implemented with the Rydberg atomic ensemble is demonstrated, which is realized by cascaded Ryd Berg excitation in a cesium vapor cell, which results in stochastic switching between the two states.
Uncovering the nonequilibrium phase structure of an open quantum spin system
We experimentally and theoretically investigate the non-equilibrium phase structure of a well-controlled driven-disspative quantum spin system governed by the interplay of coherent driving,
Interplay between thermal Rydberg gases and plasmas
We investigate the phenomenon of bistability in a thermal gas of cesium atoms excited to Rydberg states. We present both measurements and a numerical model of the phenomena based on collisions. By
Phase Diagram and Self-Organizing Dynamics in a Thermal Ensemble of Strongly Interacting Rydberg Atoms
Far-from-equilibrium dynamics that lead to self-organization are highly relevant to complex dynamical systems not only in physics but also in life, earth, and social sciences. However, it is
Phase diagram and self-organising dynamics in a strongly-interacting thermal Rydberg ensemble.
Abstract Far-from equilibrium dynamics that lead to self-organization are highly relevant to complex dynamical systems not only in physics, but also in life-, earth-, and social sciences. It is
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.
Study of the effect of super-atom dephasing on Rydberg blockade in thermal vapor
We present a theoretical model with a large number of interacting atoms that can be used to study the Rydberg blockade in thermal vapor. Exact calculations for two, three and four interacting atoms


A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
