Quantum lithography with classical light: Generation of arbitrary patterns
(American Physical Society, 2007)
Based on our previous scheme [Hemmer , Phys. Rev. Lett. 96, 163603 (2006)] we show the procedures to obtain any one- or two-dimensional pattern by multiple exposures. A key modification to the resonance condition is made ...
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, ...
Subwavelength optical microscopy in the far field
(American Physical Society, 2011)
We present a procedure for subwavelength optical microscopy. The identical atoms are distributed on a plane and shined with a standing wave. We rotate the plane to different angles and record the resonant fluorescence ...
Correlation of photon pairs from the double Raman amplifier: Generalized analytical quantum Langevin theory
(American Physical Society, 2007)
We present a largely analytical theory for two-photon correlations G((2)) between Stokes (s) and anti-Stokes (a) photon pairs from an extended medium (amplifier) composed of double-Lambda atoms in counterpropagating geometry. ...
Effects of noise and parameter deviations in a bichromatic Raman white light cavity
(American Physical Society, 2010)
We analyze the effects of noise and parameter deviations in a bichromatic Raman type white light cavity, with potential applications in precision measurements. The results show that the dispersion variation induced by ...
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 ...
Electromagnetically induced transparency inside the laser cavity: Switch between first-order and second-order phase transitions
(American Physical Society, 2008)
We investigate the effect of electromagnetically induced transparency inside a laser cavity. By changing the intensity of an external drive field, we can control the absorption to the laser field. A semiclassical analysis ...
Reversing entanglement change by a weak measurement
(American Physical Society, 2010)
Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
Entanglement criteria and nonlocality for multimode continuous-variable systems RID B-8901-2008
(American Physical Society, 2009)
We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multimode continuous variable systems. The separability conditions are established from partial transposition (PT) in ...
