Quantum Interferometry and Correlated Two-Electron Wave-Packet Observation in Helium
Quantum Interferometry Correlated Two-Electron Wave-Packet Observation Helium Atomic Physics
2012/5/17
The concerted motion of two or more bound electrons governs atomic and molecular non-equilibrium processes and chemical reactions. It is thus a long-standing scientific dream to measure the dynamics o...
Spectra and ground states of one- and two-dimensional laser-driven lattices of ultracold Rydberg atoms
Spectra ground states one- and two-dimensional laser-driven lattices ultracold Rydberg atoms
2012/2/28
We investigate static properties of laser-driven, ultracold Rydberg atoms confined to one- and two-dimensional uniform lattices in the limit of vanishing laser coupling. The spectral structure of squa...
Over the past few years we have built an apparatus to demonstrate the entanglement of neutral Rb atoms at optically resolvable distances using the strong interactions between Rydberg atoms. Here we re...

2011/9/9
We study the decay of two repulsively interacting bosons tunneling through a delta potentialm barrier by direct numerical solution of the time-dependent Schr¨odinger equation. The solutions are analyz...
Generating Molecular Rovibrational Coherence by Two-Photon Femtosecond Photoassociation of Thermally Hot Atoms

2011/8/18
Abstract: The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms. In a therm...

Two-center harmonic spectra aligned polar molecules
2011/9/5
We extend a model of two-center interference to include the superposition of opposite orientations in aligned polar molecules. We show that the position of the minimum in the harmonic spectrum from bo...

2011/9/2
We present a method for measuring atomic parity violation in the absence of static external electric and magnetic elds. Such measurements can be achieved by observing the interference of parity conse...

Carrier-envelope phase sensitive two-level systems
2011/9/2
We theoretically study the carrier-envelope phase dependent inversion generated in a two-level system by excitation with a few-cycle pulse. Based on the invariance of the inversion under time reversal...

2011/9/1
We report a study on light force on a beam of neutral two-level atoms superimposed upon a few-cycle pulsed Gaussian laser field under both resonant and off-resonant condition. The phenomena of focusin...
