Excitonic transport in static-disordered one dimensional systems is studied in the presence of thermal fluctuations that are described by the Haken–Strobl–Reineker model. For short times, non-diffusiv...
Stochastic treatments of magnetic resonance spectroscopy and optical spectroscopy require evaluations of functions like int_0^t Q(s)ds)>, where t is time, Q(s) is the value of a stochastic proc...
Abstract: An approach to fast entanglement generation based on Rydberg dephasing of collective excitations (spin-waves) in large, optically thick atomic ensembles is proposed. Long-range $1/r^3$ atomi...
We numerically model the evolution of a pair of coherently split quasicondensates. A truly one-dimensional case is assumed, so that the loss of the (initially high) coherence between the two quasico...
We analyze the critical behavior of the dephasing rate induced by short-range electron-electron interaction near an Anderson transition of metal-insulator or quantum Hall type. The corresponding expon...
Femtosecond dynamics of coherent optical phonons in GeTe/Sb2Te3 superlattices (SLs), a new class of semiconductor SLs with three different states, have been investigated by using a reflectiontype pum...
The effect of dephasing on electron transport through a benzene molecule is carefully examined using a phenomenological model introduced by B¨uttiker. Within a tight-binding framework all the calcula...
Femtosecond dynamics of coherent optical phonons in GeTe/Sb$_{2}$Te$_{3}$ superlattices (SLs), a new class of semiconductor SLs with three different states, have been investigated by using a reflecti...
We have performed spectroscopic measurements of a superconducting qubit dispersively coupled to a nonlinear resonator driven by a pump microwave field. Measurements of the qubit frequency shift provid...
We study electron-phonon interaction induced decoherence between two-electron singlet and triplet states in a semiconductor double quantum dot using a spin-boson model. We investigate the onset and ti...
We study the entanglement dynamics for a two-spin system coupled to a spin environment of different configurations by z-x type interaction. The models considered in this paper are solved both analyti...
We present an analytic description of the effects of dephasing processes on stimulated Raman adiabatic passage in a tripod quantum system. To this end, we develop an effective two-level model.Our ana...
In this article we treat the subject of chaotic environments with few degrees of freedom in quantum communication by investigating a conservative dynamical map as a model of a dephasing quantum channe...
2007Vol.48No.2pp.335-338DOI: Optical Bloch Equations Modified with Phonon-Induced Intensity-Dependent Dephasing ZHOU Guang-Hua,1 LI Yao-Yi,2 CHENG Mu-Tian,1 LIU Shao-Ding,1 and WA...
We discuss orbital entanglement in mesoscopic conductors, focusing on the effect of dephasing. The entanglement is detected via violation of a Bell Inequality formulated in terms of zero-frequency cur...
