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 ...
