Stripe-tetragonal phase transition in the 2D Ising model with dipole interactions: Partition-function zeros approach
Jacyana S. M. Fonseca, Leandro G. Rizzi, Nelson A. Alves
We have performed multicanonical simulations to study the critical behavior of the two-dimensional Ising model with dipole interactions. This study concerns the thermodynamic phase…
Generalized Metropolis dynamics with a generalized master equation: An approach for time-independent and time-dependent Monte Carlo simulations of generalized spin systems
Roberto da Silva, Jose Roberto Drugowich de Felicio, Alexandre Souto Martinez
The extension of Boltzmann-Gibbs thermostatistics, proposed by Tsallis, introduces an additional parameter to the inverse temperature . Here, we show that a previously intro…
The influence of memory in deterministic walks in random media: analytical calculation within a mean field approximation
Cesar Augusto Sangaletti Tercariol, Alexandre Souto Martinez
Consider a random medium consisting of points randomly distributed so that there is no correlation among the distances. This is the random link model, which is the high dimensional…
Arithmetical and geometrical means of generalized logarithmic and exponential functions: generalized sum and product operators
Tiago Jose Arruda, Rodrigo Silva Gonzalez, Cesar Augusto Sangaletti Tercariol +1
One-parameter generalizations of the logarithmic and exponential functions have been obtained as well as algebraic operators to retrieve extensivity. Analytical expressions for the…
An alternative order parameter for the 4-state Potts model
H. A. Fernandes, E. Arashiro, A. A. Caparica +1
We have investigated the dynamic critical behavior of the two-dimensional 4-state Potts model using an alternative order parameter first used by Vanderzande [J. Phys. A: Math. Gen.…
