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…
Continuous local model for two-dimensional spin ice
J. E. da Fonseca, C. W. Morais, A. L. Mota +1
We propose a classical model Hamiltonian with a ground state presenting a spin ice structure. We analyze the introduction of metastable excitations on this ground state, showing th…
Momentum Space Regularizations and the Indeterminacy in the Schwinger Model
C. W. Morais, A. L. Mota
We revisited the problem of the presence of finite indeterminacies that appear in the calculations of a Quantum Field Theory. We investigate the occurrence of undetermined mathemat…
Phase Transition in Asymmetrical Superfluids I: Equal Fermi Surfaces
Heron Caldas, C. W. Morais, A. L. Mota
In this paper, we study phase transitions in asymmetrical fermion superfluids. In this scenario, the candidates to form pair are particles with mismatched masses and chemical poten…
