Replica Exchange Monte Carlo Simulations of the Ising Spin Glass: Static and Dynamic Properties
Monte Carlo spin glass
2014/11/20
Spin glasses have been the subject of intense study and considerable controversy for decades, and the low-temperature phase of short-range spin glasses is still poorly understood. Our main goal is to ...
Noncanonical statistics of a spin-boson model: Theory and exact Monte Carlo simulations
Non Canonical statistics a spin-boson model Theory exact Monte Carlo simulations
2014/9/24
Equilibrium canonical distribution in statistical mechanics assumes weak system-bath coupling (SBC). In real physical situations this assumption can be invalid, and equilibrium quantum statistics of t...

Stable marriage problem Monte Carlo simulations influence of preferrence corelation relaxation time
2011/7/5
In this paper we consider stable marriage problem under the Monte Carlo
simulations. We investigate how correlation in lists of preferrences can affect
simulation results such as: relaxation time, t...
REAS3: Monte Carlo simulations of radio emission from cosmic ray air showers using an "end-point" formalism
REAS3 Monte Carlo simulations
2011/1/11
In recent years, the freely available Monte Carlo code REAS for modelling radio emission from cosmic ray air showers has evolved to include the full complexity of air shower physics. However, it turne...
