Finite-Hilbert-basis-set calculations for the angular distribution of ionized electrons produced in p+H impact at 20 keV
(American Physical Society, 2004)
We present a different method of extracting the angular distribution of ejected electrons in an ion-atom collision from a two-centered finite Hilbert basis-set calculation. We obtain good agreement with experiment for a ...
Buffer-gas-induced absorption resonances in Rb vapor RID B-9041-2008
(American Physical Society, 2004)
We observe transformation of the electromagnetically induced transparency (EIT) resonance into an absorption resonance in a Lambda interaction configuration in a cell filled with Rb-87 and a buffer gas. This transformation ...
Tunable phase control for subluminal to superluminal light propagation
(American Physical Society, 2004)
We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended Lambda-type system with two extra control fields and an extra energy level. Phase variation ...
Large negative and positive delay of optical pulses in coherently prepared dense Rb vapor with buffer gas RID B-9041-2008
(American Physical Society, 2004)
We experimentally study the group time delay for a light pulse propagating through hot Rb-87 vapor in the presence of a strong coupling field in a Lambda configuration. We demonstrate that the ultraslow pulse propagation ...
Quantum disentanglement eraser: A cavity QED implementation
(American Physical Society, 2004)
A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to acquire single-qubit ...
Cavity QED-based quantum walk
(American Physical Society, 2004)
We discuss a possible experimental scheme for the implementation of a quantum walk. The scheme is based on the passage of an atom inside a high-Q cavity. The chirality is characterized by the atomic states and the displacement ...
Measurement of entangled states via atomic beam deflection in Bragg's regime RID C-6638-2008 RID A-4660-2010
(American Physical Society, 2004)
We propose a scheme for the measurement of joint photon statistics and Wigner function of the entangled field states between two separate cavities. The scheme utilizes the momentum state of the two-level atoms in Bragg's ...
