2014/5/28
The multilayer multiconfiguration time-dependent Hartree (ML-MCTDH) method is applied to simulate the quantum dynamics and thermal rate constant of the Azzouz-Borgis model of proton transfer in a pola...

Highly anisotropic hydrodynamics -- discussion model assumptions forms of the initial conditions
2011/1/7
The model assumptions of the recently formulated framework of highlyanisotropic and strongly-dissipative hydrodynamics (ADHYDRO) are analyzed.In particular, we study dependence of numerical results on...

Numerous studies have identi ed large quantum mechanical e ects in the dynamics of liquid
water. In this paper, we suggest that these e ects may have been overestimated due to the use of rigid water ...

Nonperturbative Analysis Quantum Mechanical Model Unstable Particles
2010/11/9
We present a detailed non-perturbative analysis of the time-evolution of a well-known quantum-mechanical system - a particle between potential walls - describing the decay of unstable states. For suff...
Initial correlations in open system's dynamics: The Jaynes-Cummings model
Initial correlations open system's dynamics Jaynes-Cummings model
2010/11/8
Employing the trace distance as a measure for the distinguishability of quantum states, we study the influence of initial correlations on the dynamics of open systems. We concentrate on the Jaynes-Cu...
We study the evolution of entanglement, quantum correlation and classical correlation for the one dimensional XY model in external transverse magnetic field. The system is initialized in the full pola...
On the basis of a lemma designed to decide whether a discrete system decoheres or not with no need of computer simulations, in this paper we analyze the well-known spin-bath model. The lemma allows us...
