A spectral investigation of criticality and crossover effects in two and three dimensions: Short timescales with small systems in minute random matrices
Eliseu Venites Filho, Roberto da Silva, José Roberto Drugowich de Felício
Random matrix theory, particularly using matrices akin to the Wishart ensemble, has proven successful in elucidating the thermodynamic characteristics of critical behavior in spin…
Mean-field criticality explained by random matrices theory
Roberto da Silva, Heitor C. Fernandes, Eliseu Venites Filho +2
How a system initially at infinite temperature responds when suddenly placed at finite temperatures is a way to check the existence of phase transitions. It has been shown in [R. d…
Efficient Computational method using random matrices describing critical thermodynamics
Roberto da Silva, Eliseu Venites, Sandra D. Prado +1
Our research highlights the effectiveness of utilizing matrices akin to Wishart matrices, derived from magnetization time series data under specific dynamics, to elucidate phase tr…
Transfer matrix in counting problems made easy
Roberto da Silva, Silvio R. Dahmen, J. R. Drugowich de Felício
The transfer matrix is a powerful technique that can be applied to statistical mechanics systems as, for example, in the calculus of the entropy of the ice model. One interesting w…
Non-equilibrium critical dynamics of the two-dimensional Ashkin-Teller model at the Baxter line
H. A. Fernandes, R. da Silva, A. A. Caparica +1
We investigate the short-time universal behavior of the two dimensional Ashkin-Teller model at the Baxter line by performing time-dependent Monte Carlo Simulations. First, as prepa…
