A spectral investigation of criticality and crossover effects in two and three dimensions: Short timescales with small systems in minute random matrices

Autor: Filho, Eliseu Venites, da Silva, Roberto, de Felício, José Roberto Drugowich

Random matrix theory, particularly using matrices akin to the Wishart ensemble, has proven successful in elucidating the thermodynamic characteristics of critical behavior in spin systems across varying interaction ranges. This paper explores the app

Generalized Metropolis dynamics with a generalized master equation: An approach for time-independent and time-dependent Monte Carlo simulations of generalized spin systems

Autor: da Silva, Roberto, de Felicio, Jose Roberto Drugowich, Martinez, Alexandre Souto

Publikováno v: Phys. Rev. E 85, 066707 (2012)

The extension of Boltzmann-Gibbs thermostatistics, proposed by Tsallis, introduces an additional parameter $q$ to the inverse temperature $\beta$. Here, we show that a previously introduced generalized Metropolis dynamics to evolve spin models is not

We study the critical relaxation of the helix-coil transition in all-atom models of polyalanine chains. We show that at the critical temperature the decay of a completely helical conformation can be described by scaling relations that allow us estima
