2D triangular Ising model with bond phonons: An entropic simulation study
R. M. L. Nascimento, Claudio J. DaSilva, L. S. Ferreira +1
In this work, we study and evaluate the impact of a periodic spin-lattice coupling in an Ising-like system on a 2D triangular lattice. Our proposed simple Hamiltonian considers thi…
An entropic approach to analyze phase transitions in the q = 3 Potts model
L. S. Ferreira, L. N. Jorge, C. J. DaSilva +1
Boltzmann's microcanonical entropy is the link between statistical physics and thermodynamics, forasmuch as the behavior of any thermodynamic quantity is directly related to the nu…
Rotational symmetry breaking potential for two-dimensional magnets
Claudio J DaSilva, L. S. Ferreira, A. A. Caparica
Here we present a new perspective to the breakdown of ferromagnetic order in two-dimensional spin-lattice models employing the rotation of the underlying lattice. Using an Ising sp…
An entropic simulational study of the spin- Baxter-Wu model in a crystal field
L. N. Jorge, P. H. L. Martins, C. J. DaSilva +2
We investigate the critical behavior of the two-dimensional spin- Baxter-Wu model in a crystal field using entropic sampling simulations with the joint density of states. We obt…
Thoroughly analysis of the phase diagram for the Bell-Lavis model: An entropic simulational study
L. S. Ferreira, L. N. Jorge, Cláudio J. DaSilva +1
In this work, we investigate the Bell-Lavis model using entropic simulations for several values of the energy parameters. The phase diagram and the ground state configur…
Unveiling phase transitions in 1D systems with short-range interactions
L. S. Ferreira, L. N. Jorge, Cláudio J. DaSilva +2
The statement that any phase transition is related to the appearance or disappearance of long-range spatial correlations precludes a finite transition temperature in one-dimensiona…
