Quadratic Diffusion Monte-Carlo Algorithms for Solving Atomic Many-Body Problems
(American Physical Society, 1990)
The diffusion Monte Carlo algorithm with and without importance sampling is analyzed in terms of the algorithm's underlying transfer matrix. The crucial role played by the Langevin algorithm in the importance-sampling ...
Influence of pump-phase fluctuations on entanglement generation using a correlated spontaneous-emission laser
(American Physical Society, 2007)
In this paper, we study the effect of phase fluctuations of the pump field upon the entanglement generation in a two-photon correlated emission laser (CEL). We consider initial vacuum and coherent state for the two-cavity ...
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 ...
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, ...
Fast noise in the Landau-Zener theory RID B-5617-2009
(American Physical Society, 2003)
We study the influence of a fast noise on Landau-Zener transitions. We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the ...
Disorder-induced magnetic memory: Experiments and theories RID F-6415-2010 RID C-4384-2008 RID B-1163-2008 RID A-3020-2010

Engineering exotic phases for topologically protected quantum computation by emulating quantum dimer models RID B-7826-2008

Electron-Ion Dynamics - a Technique for Simulating both Electronic-Transitions and Ionic Motion in Molecules and Materials
(American Physical Society, 1994)
Reversing entanglement change by a weak measurement
(American Physical Society, 2010)
Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
Theory of weak localization in ferromagnetic (Ga,Mn)As
(American Physical Society, 2009)
We study quantum interference corrections to the conductivity in (Ga,Mn)As ferromagnetic semiconductors using a model with disordered valence-band holes coupled to localized Mn moments through a p-d kinetic-exchange ...
