Computational Experiments for the Problem of
... There is a well known site on which posted solvers for SAT [21]. We have used algorithms from [21]: fgrasp and posit. For solution of the problem, we have used a heterogeneous cluster. Each test was run on a cluster of at least 100 nodes. Note that due to restrictions on computation time (20 hours) ...

Quantum critical states and phase transitions in the presence of non
... there is no sharp distinction between the different phases of the low dimensional systems we consider here at any T > 0. In certain cases it was argued that a non equilibrium drive may act as an effective temperature[17, 18]. In marked contrast, we find that the external 1/f noise is only a marginal ...

The Mean-Field Limit for the Dynamics of Large Particle

The state of the typical particle is given by its phase space density; the force field exerted by the N other particles on this typical particle is approximated by the average with respect ...

Classical phase-space analysis of vibronically coupled systems
... recently a “mapping approach” to the semiclassical description of nonadiabatic dynamics has been proposed [43,44]. The approach consists of two steps: A quantum-mechanical exact transformation of discrete onto continuous DoF (the “mapping”) and a standard classical or semiclassical treatment of the ...
