Tricritical behavior of a relativistic field theory in one dimension
Heron Caldas, A. L. Mota
The tricritical behavior in a class of one-dimensional (1D) field theories that exhibit spontaneous symmetry breaking at zero temperature and chemical potential is analyzed. In the…
The Schwinger and Chiral Schwinger Models in a Non-perturbative Spectral Regularization
L. F. Eleotério, G. A. Oliveira, E. W. Dias +2
We investigate the employment of a non-perturbative regularization scheme -- the spectral regularization, which is based on the gauge technique, previously implemented in the conte…
Finding the Dominant Zero of the Energy Probability Distribution
J. J. Carvalho, A. L. Mota
In this work, we present a method to locate the dominant zero of the Energy Probability Distribution (EPD) Zeros method applied to the study of phase transitions. The technique str…
Phase Transition and Monopoles Densities in a Nearest Neighbors Two-Dimensional Spin Ice Model
C. W. Morais, D. N. de Freitas, A. L. Mota +1
In this work, we show that, due to the alternating orientation of the spins in the ground state of the artificial square spin ice, the influence of a set of spins at a certain dist…
Finite Temperature Phase Diagram of Quasi-Two-Dimensional Imbalanced Fermi Gases Beyond Mean-Field
M. A. Resende, A. L. Mota, R. L. S. Farias +1
We investigate the superfluid transition temperature of quasi-two-dimensional imbalanced Fermi gases beyond the mean-field approximation, through the second-order (or induced) inte…
On the coupling constant bounds implying area decay of Wilson loop for Z2 lattice gauge theories with Wilson action Boltzmann factor given by bond variables described by transverse Ising model
F. C. Sá Barreto, A. L. Mota
We obtain correlation functions for lattice gauge theories with action Boltzmann factor given by bond variables described by transverse Ising model and apply them to obtain area de…
