Anomalous Broadening in Driven Dissipative Rydberg Systems.
We observe interaction-induced broadening of the two-photon 5s-18s transition in ^{87}Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by nearly 2 orders of magnitude with increasing atomic density and excitation strength, with corresponding suppression of resonant scattering and enhancement of off-resonant scattering. We attribute the increased linewidth to resonant d...
متن کاملL-changing Collisions in Cold Rydberg Gases
Using spectroscopic methods and time-resolved electron counting, it is found that clouds of cold Rydberg atoms can emit electrons over a surprisingly long time scale. Our observations are explained by l-mixing collisions between Rydberg atoms and slow electrons. The thereby created high-angular-momentum Rydberg atoms thermally ionize slowly and with large probabilities. Calculations supporting ...
متن کاملCold Rydberg gases and ultra-cold plasmas
We briefly highlight recent developments in the complementary fields of cold Rydberg gases and ultra-cold plasmas and provide a short overview of the articles in this special issue.
متن کاملNonlocal nonlinear optics in cold Rydberg gases.
We present an analytical theory for the nonlinear optical response of a strongly interacting Rydberg gas under conditions of electromagnetically induced transparency. Simple formulas for the third-order optical susceptibility are derived and shown to be in excellent agreement with recent experiments. The obtained expressions reveal strong nonlinearities, which in addition are of highly nonlocal...
متن کاملA Variational Approach to the Analysis of Dissipative Electromechanical Systems
We develop a method for systematically constructing Lagrangian functions for dissipative mechanical, electrical, and electromechanical systems. We derive the equations of motion for some typical electromechanical systems using deterministic principles that are strictly variational. We do not use any ad hoc features that are added on after the analysis has been completed, such as the Rayleigh di...
