Atom microscopy via two-photon spontaneous emission spectroscopy RID A-5077-2009
(American Physical Society, 2009)
We study subwavelength position measurement via spontaneous emission spectroscopy with two photons. Our model systems are a single Lambda-type three-level atom, in which a dual interaction generates two independent photons, ...
Continuous-variable entanglement in a correlated spontaneous emission laser
(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 ...
Disentanglement in a two-qubit system subjected to dissipation environments RID A-4660-2010
(American Physical Society, 2007)
We investigate the time evolution of entanglement of various entangled states of a two-qubit system exposed to either thermal or squeezed reservoirs. We show that, except for the vacuum reservoir, the sudden-death of ...
Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses
(American Physical Society, 2005)
It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
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, ...
Spectra and magnetic properties of large spins in external fields
(American Physical Society, 1999)
Spectra and magnetic properties of large spins J (e.g., spins possessed by ions or molecules), placed into a crystal electric field (CEF) of an arbitrary symmetry point group, are shown to change drastically when J changes ...
Proposal for a Loophole-Free Test of the Bell Inequalities
(American Physical Society, 1995)
A proposal for an experimental realization of Bohm's spin-1/2 particle version of the Einstein-Podolsky-Rosen experiment is described. Two Hg-199 atoms, each with nuclear spin 1/2, are produced in an entangled state with ...
K-Shell Hole Production by Light-Ions in Region Eta 1/2 =] 1
(American Physical Society, 1977)
Observation of picosecond superfluorescent pulses in rubidium atomic vapor pumped by 100-fs laser pulses
(American Physical Society, 2010)
We study the superfluorescence (SF) from a gas of rubidium atoms. The atoms of a dense vapor are excited to the 5D state from the 5S state by a two-photon process driven by 100-fs laser pulses. The atoms decay to the 6P ...
Entanglement conditions for two-mode states: Applications
(American Physical Society, 2006)
We examine the implications of several recently derived conditions [Hillery and Zubairy, Phys. Rev. Lett. 96, 050503 (2006)] for determining when a two-mode state is entangled. We first find examples of non-Gaussian states ...
