(American Physical Society, 2010)The behavior of the Goos-Hanchen (GH) shifts in the reflected and transmitted light beam which is incident on a cavity containing an intracavity medium of three-level or four-level atoms with electromagnetically induced ...
-
(American Physical Society, 2007)We report the observation of a coherent multimode instability in quantum cascade lasers (QCLs), which is driven by the same fundamental mechanism of Rabi oscillations as the elusive Risken-Nummedal-Graham-Haken (RNGH) ...

Collinear Laser-Beam Ion-Beam Measurement of the Mean Lifetime of the Ar Ii 4p'2f-Degrees-7/2 Level (American Physical Society, 1993)The mean lifetime tau of the 4p'F-2(7/2)-degrees level of Ar II has been measured using a variant of the collinear laser-beam-fast-ion-beam spectroscopy technique. Our variant requires no mechanical motion or laser frequency ...
-
(American Physical Society, 2003)We emphasize that there is no spin-statistics connection in nonrelativistic quantum mechanics. In several recent papers [including Phys. Rev. A 67, 042102 (2003)], quantum mechanics is modified so as to force a spin-statistics ...

(2013-02-15)As objects continue to be placed into space, Earth orbiting debris are becoming a prominent issue. To counteract this, NASA’s Marshall Space Flight Center’s (MSFC) Engineering Directorate has funded a project to create a ...
-
(American Physical Society, 2001)The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
-
(American Physical Society, 2000)A nonequilibrium approach to the dynamics and statistics of the condensate of an ideal N-atom Bose gas cooling via interaction with a thermal reservoir using the canonical ensemble is developed. We derive simple analytical ...

(American Physical Society, 1975)
-
(American Physical Society, 2005)We discuss the generation and evolution of entangled light in a correlated spontaneous emission laser. The master equation for the two-mode field in a cavity is derived and solved analytically. The time-dependent characteristic ...
-
(American Physical Society, 2008)We present a proposal to manipulate the Goos-Hanchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral ...
-
(American Physical Society, 2010)A unitary transformation approach is used to study the energy level shift of the atom coupled to both a vacuum electromagnetic field and a driving laser. The Lamb shift of the energy levels is shown to depend on the Rabi ...
-
(American Physical Society, 2011)The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
-
(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. ...

-
(American Physical Society, 2008)Nonperturbative analytical quantum treatments of strong-field laser-atom interaction are essentially based on the assumption that binding forces are negligible once the electron is emitted because the further dynamics are ...

(2014-02-12)Since the first successful liver transplant in 1968 the surgery has become very common and 6,291 patients received liver transplants in 2010 in the United States. However, the monitoring methods used post-surgery, in the ...
