Gaussian-state entanglement in a quantum beat laser
(American Physical Society, 2011)
Recently quantum beat lasers have been considered as a source of entangled radiation [S. Qamar, F. Ghafoor, M. Hillery, and M. S. Zubairy, Phys. Rev. A 77, 062308 (2008)]. We investigate and quantify the entanglement of ...
Experimental studies of di-jet survival and surface emission bias in Au plus Au collisions via angular correlations with respect to back-to-back leading hadrons
(American Physical Society, 2011)
We report first results from an analysis based on a new multi-hadron correlation technique, exploring jet-medium interactions and di-jet surface emission bias at the BNL Relativistic Heavy Ion Collider (RHIC). Pairs of ...
Quantum teleportation of four-dimensional qudits
(American Physical Society, 2010)
A protocol for the teleportation of arbitrary quantum states of four-dimensional qudits is presented. The qudit to be teleported is encoded in the combined state of two ensembles of atoms placed in a cavity at the sender's ...
Controllable optical switch using a Bose-Einstein condensate in an optical cavity
(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 ...
Stellar reaction rate for (22)Mg + p -> (23)Al from the asymptotic normalization coefficient in the mirror nuclear system (22)Ne + n -> (23)Ne
(American Physical Society, 2010)
The production of (22)Na in ONe novae can be influenced by the (22)Mg(p,gamma)(23)Al reaction. To investigate this reaction rate at stellar energies, we have determined the asymptotic normalization coefficient (ANC) for ...
Plasmon mass and Drude weight in strongly spin-orbit-coupled two-dimensional electron gases
(American Physical Society, 2011)
Spin-orbit-coupled two-dimensional electron gases (2DEGs) are a textbook example of helical Fermi liquids, i.e., quantum liquids in which spin (or pseudospin) and momentum degrees of freedom at the Fermi surface have a ...
Critical behavior and universality in Levy spin glasses
(American Physical Society, 2011)
Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share the same universality class as Ising spin ...
Precise half-life measurement of the superallowed beta(+) emitter (38)K(m)
(American Physical Society, 2010)
The half-life of (38)K(m) has been measured to be 924.46(14) ms, a result that is a factor of two more precise than any of the five previous measurements of this quantity. The previous results are not consistent with one ...
Modeling of diffusion of injected electron spins in spin-orbit coupled microchannels
(American Physical Society, 2010)
We report on a theoretical study of spin dynamics of an ensemble of spin-polarized electrons injected in a diffusive microchannel with linear Rashba and Dresselhaus spin-orbit coupling. We explore the dependence of the ...
Numerical studies of a one-dimensional three-spin spin-glass model with long-range interactions
(American Physical Society, 2010)
We study a p-spin spin-glass model to understand if the finite-temperature glass transition found in the mean-field regime of p-spin models, and used to model the behavior of structural glasses, persists in the nonmean-field ...
