Sep 14, 2010· Abstract: After deriving the isothermal Hellmann-Feynman theorem (IHFT) that is suitable for mixed states in a canonical ensemble, we use this theorem to obtain the isothermal magnetic-field sweep theorems for the free, average and trapping energies, and for the entropy, specific heat, pressure and atomic compressibility of strongly-correlated ultra-cold quantum gases.
May 18, 2012· In particular, the interaction strength between such atoms can be varied over an enormous range. In a mesoscopic ensemble, such strong, long-range interactions can be used for fast preparation of desired many-particle states. We generated Rydberg excitations in an ultra-cold atomic gas and subsequently converted them into light.
Ultracold Molecular Assembler . The Team: Lee Liu, Yichao Yu, Jessie Zhang, Kennth Wang, Lewis Picard, Eliot Fenton, Dr. Jon Hood, Dr. Yen-Wei Lin Single molecule detections and manipulations have been powerful approaches to study systems without ensemble averaging. We take this inspiration to study chemistry and physics at the ultracold regime ...
We study the nonlinear dynamics of an ensemble of cold trapped atoms with a hyperfine transition magnetically coupled to a resonant microwave cavity mode. Despite the minute single-atom coupling, one obtains strong coupling between collective

In our laboratories we generate Rydberg excitations in an ultra-cold atomic gas and convert them into light. For principal quantum numbers n beyond ~70, we are able to realize conditions where no more than a single excitation is retrieved from the entire mesoscopic ensemble of atoms.

The Quantum World of Ultra-Cold Atoms and Light is a trilogy, which presents the quantum optics way of thinking and its applications to quantum devices. This book — The Physics of Quantum-Optical Devices — provides a comprehensive treatment of theoretical quantum optics.
In the experiment, they achieved quantum entanglement between two ultra-cold atomic clouds, known as Bose-Einstein condensates, in which the two ensembles of atoms were spatially separated from each other. Quantum entanglement was discovered by Schrödinger and later studied by Einstein and other scientists in the last century.
Nov 18, 2009· Abstract: We demonstrate a cooperative optical non-linearity caused by dipolar interactions between Rydberg atoms in an ultra-cold atomic ensemble. By coupling a probe transition to the Rydberg state we map the strong dipole-dipole interactions between …

Our long term goal is to achieve quantum networking based on telecommunications quantum repeater. We have proposed a new strategy for a quantum repeater at telecommunications wavelengths with long-lived atomic memory, and we have experimentally demonstrated its critical elements in a cold atomic ensemble.
