Simulated expansion of an ultra-cold, neutral plasma
The details of recent calculations of the expansion of ultra-cold, neutral plasmas are given. The calculations are performed at several levels. The simplest level assumes an ansatz for the form of the electron and ion density; the result is a simple, ordinary differential equation which can be easily solved. The medium level of sophistication assumes the electrons are in thermal equilibrium but...
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 ...

We present an introductory review of the latest advancements cold Rydberg atom research. First, we briefly summarize the exaggerated properties of Rydberg atoms, and we discuss the new perspectives of Rydberg atom research that has been enabled by laser cooling and trapping technique. We then highlight the latest developments and achievements in the newly emerged research fields for Rydberg mol...
متن کاملControlling the interactions between cold Rydberg atoms by a time-varying electric field
Long-range interactions between cold Rydberg atoms are being investigated for neutral-atom quantum computing, quantum simulations, phase transitions in cold Rydberg gases and other applications. Fine tuning of the interaction strength can be implemented using Förster resonances between Rydberg atoms controlled by an electric field. The observation of the Stark-tuned Förster resonances between R...
