High-resolution mapping of the phase boundary of the honeycomb-lattice Blume--Capel ferromagnet
Eluiz C. M. Filho, Claudio J. DaSilva
We present a high-resolution numerical study of the spin-1 Blume--Capel ferromagnet on the honeycomb lattice (). Wang--Landau estimates of the joint density of states $Ω(E_1,E…
Berezinskii-Kosterlitz-Thouless transition in the XY model on the honeycomb lattice: A comprehensive Monte Carlo analysis
Felipe E. F. de Andrade, L. N. Jorge, Claudio J. DaSilva
In this paper, we thoroughly examined the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in the two-dimensional XY model on the honeycomb lattice. To address its thermodyna…
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…
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…
Efficient simulated tempering with approximated weights: Applications to first-order phase transitions
A. Valentim, Cláudio J. daSilva, Carlos E. Fiore
Simulated tempering (ST) has attracted a great deal of attention in the last years, due to its capability to allow systems with complex dynamics to escape from regions separated by…
Static critical behavior of the states Potts model: High-resolution entropic study
A. A. Caparica, Salviano A. Leão, Claudio J. DaSilva
Here we report a precise computer simulation study of the static critical properties of the two-dimensional -states Potts model using very accurate data obtained from a modified…
Equivalence between microcanonical methods for lattice models
Carlos E. Fiore, Cláudio J. DaSilva
The development of reliable methods for estimating microcanonical averages constitutes an important issue in statistical mechanics. One possibility consists of calculating a given…
Finite-size scaling considerations on the ground state microcanonical temperature in entropic sampling simulations
Álvaro de Almeida Caparica, Cláudio José DaSilva
In this work we discuss the behavior of the microcanonical temperature obtained by means of numerical entropic sampling studies. It is observed t…
