Measurement of ground-state decoherence via interruption of coherent population trapping
(American Physical Society, 2007)
We examine the role of ground-state coherence on the fluorescence from the excited state in a three-level Lambda system under continuous-wave excitation. When resonantly pumped, the fluorescence is strongly affected by any ...
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 ...
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 ...
Aharonov-Casher effect in a two-dimensional hole ring with spin-orbit interaction RID B-3617-2008 RID A-1315-2011
(American Physical Society, 2007)
We study the quantum interference effects induced by the Aharonov-Casher phase in a ring structure in a two-dimensional heavy-hole (HH) system with spin-orbit interaction realizable in narrow asymmetric quantum wells. The ...
On the informative value of the largest sample element of log-Gumbel distribution
(Versita, 2007-12)
Extremes of stream flow and precipitation are commonly modeled by heavytailed
distributions. While scrutinizing annual flow maxima or the peaks over
threshold, the largest sample elements are quite often suspected to be ...
Word frequency modulates the Basic Orthographic Syllabic Structure (BOSS) effect in English polysyllable word recognition
(Psychology Press - Taylor and Francis, 2007)
Do native readers segment polysyllabic words based on orthographic/morphological criteria or phonological criteria? Research by Taft (1979, 2001) argues in support of the former, as readers were faster in split-word lexical ...
An Open Source Alternative for Libraries
(2007-06)
As Linux becomes a major operating system and Apache becomes the most popular Web server today, the concept of Open Source Software (OSS) has been familiar to many people. Software developers from all over the world have ...
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. ...
The production of brailled instructional materials in Texas public schools
(Journal of Visual Impairments and Blindness, 2007)
Effective critical behavior of the two-dimensional Ising spin glass with bimodal interactions
(American Physical Society, 2007)
