Entangled radiation via a Raman-driven quantum-beat laser
(American Physical Society, 2009)
We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
Reversing the weak measurement of an arbitrary field with finite photon number
(American Physical Society, 2009)
For an arbitrary field with finite photon number inside a leaky cavity, we show that the null-result measurement can be conditionally reversed, using either multiple atoms or a multilevel atom. Even with photons detected, ...
Probing the quantum commutation rules through cavity QED
(American Physical Society, 2008)
We propose a cavity QED-based scheme to observe the noncommutativity between the creation and annihilation operators. By conditional measurement after the atom-field interaction in a cavity, it is possible to achieve a ...
Lamb shift due to surface plasmon polariton modes
(American Physical Society, 2008)
The Lamb shift of a hydrogen atom due to the surface plasmon polariton (SPP) modes is calculated and we observe both band edge and surface enhancement. The atom sits inside a thin metal slab which is sandwiched by two ...
