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...
4-dimensional Spin-foam Model with Quantum Lorentz Group
Quantum Group Loop Quantum Gravity Spin-foam Model
2011/3/3
We study the quantum group deformation of the Lorentzian EPRL spin-foam model. The construction
uses the harmonic analysis on the quantum Lorentz group. We show that the quantum group spin-foam model...
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...
We analyze operational risk in terms of a spin glass model. Several regimes are investigated, as a functions of the parameters that characterize the dynamics. The system is found to be robust against...

The primary goal of this paper is to prescribe the practical limitations of the two-dimensional, baroclinic, time-dependent model of Hamilton and Rattray (1978) for the Oregon-Washington continental s...

Kinetic Phase Transition the Mixed-Spin Ising Model
2010/10/19
In this work we studied a ferromagnetic mixed-spin Ising model including a single ion crystal-field term. The model system consists of two interpenetrating sublattices with spins σ = 1/2 and S = 1. Th...

2010/10/19
We studied a layered mixed-spin Ising model, with spins σ = 1/2 and S = 1, distributed on the sites of a hexagonal lattice. For this spin arrangement, any spin at one lattice site has two nearest-neig...
