A Bad Air Day in Houston
(American Meteorological Society, 2005-05-01)
A case study from the Texas Air Quality Study 2000 field campaign illustrates the complex interaction of meteorological and chemical processes that produced a high-pollution event in the Houston area on 30 August 2000. ...
Coherence-induced entanglement
(American Physical Society, 2005)
We show how atomic coherence can lead to entanglement between two thermal fields at a temperature T. We first show that the passage of a three-level atom in V configuration without coherence cannot create entanglement. ...
Optically controlled delays for broadband pulses
(American Physical Society, 2005)
We propose a scheme that provides large controllable delays for broadband optical pulses. The system is based on the steep dispersion of a coherently driven medium, in which the narrow electromagnetically induced transparency ...
Multiphase transport model for relativistic heavy ion collisions
(American Physical Society, 2005)
We describe in detail how the different components of a multiphase transport (AMPT) model that uses the heavy ion jet interaction generator (HIJING) for generating the initial conditions, Zhang's parton cascade (ZPC) for ...
Quantum-state measurement of two-mode entangled field-state in a high-Q cavity RID C-6638-2008
(American Physical Society, 2005)
We propose a scheme for the measurement of a two-mode entangled field-state in a high-Q cavity. The scheme utilizes the momentum distribution spectrum in the Raman-Nath regime of a three-level atom in V configuration. Due ...
Theory of femtosecond coherent anti-Stokes Raman backscattering enhanced by quantum coherence for standoff detection of bacterial spores
(American Physical Society, 2005)
Backscattered signal of coherent anti-Stokes Raman spectroscopy can be an extremely useful tool for remote identification of airborne particles, provided the signal is sufficiently large. We formulate a semiclassical theory ...
Event-wise (Pt) fluctuations in Au-Au collisions at root sNN=130 GeV
(American Physical Society, 2005)
We present the first large-acceptance measurement of event-wise mean transverse momentum fluctuations for Au-Au collisions at nucleon-nucleon center-of-momentum collision energy root s(NN) = 130 GeV. The observed ...
Point-contact spectroscopy investigation of superconducting-gap anisotropy in the nickel borocarbide compound LuNi2B2C
(American Physical Society, 2005)
Point contacts are used to investigate the anisotropy of the superconducting energy gap in LuNi2B2C in the ab plane and along the c axis. It is shown that the experimental curves should be described assuming that the ...
Physical limits of the ballistic and nonballistic spin-field-effect transistor: Spin dynamics in remote-doped structures
(American Physical Society, 2005)
We investigate the spin dynamics and relaxation in remotely doped two dimensional electron systems where the dopants lead to random fluctuations of the Rashba spin-orbit coupling. Due to the resulting random-spin precession, ...
Prospects for high temperature ferromagnetism in (Ga,Mn)As semiconductors
(American Physical Society, 2005)
We report on a comprehensive combined experimental and theoretical study of Curie temperature trends in (Ga,Mn)As ferromagnetic semiconductors. Broad agreement between theoretical expectations and measured data allows us ...
