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…

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…
