Dynamical generation of a gauge symmetry in the Double-Exchange model
J. M. Carmona, A. Cruz, L. A. Fernandez +7
It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of…
The U(1) phase transition on toroidal and spherical lattices
Isabel Campos, Andres Cruz, Alfonso Tarancon
We have studied the properties of the phase transition in the U(1) compact pure gauge model paying special atention to the influence of the topology of the boundary conditions. Fro…
A study of the phase transition in 4D pure compact U(1) LGT on toroidal and spherical lattices
Isabel Campos, Andres Cruz, Alfonso Tarancon
We have performed a systematic study of the phase transition in the pure compact U(1) lattice gauge theory in the extended coupling parameter space (β, γ) on toroidal and spherical…
First order signatures in 4D pure compact U(1) gauge theory with toroidal and spherical topologies
I. Campos, A. Cruz, A. Tarancón
We study the pure compact U(1) gauge theory with the extended Wilson action (β, γcouplings) by finite size scaling techniques, in lattices ranging from L=6 to L=24 in the region of…
Study of the Coulomb-Higgs transition in the Abelian Higgs Model
A. Cruz, D. Iñiguez, L. A. Fernández +2
The order of the Coulomb-Higgs transition in the U(1)-Higgs model with unfrozen modulus of the scalar field is studied. Large lattices (up to in one case) and high statistic…
A multisite microcanonical updating method
A. Cruz, L. A. Fernandez, D. Iniguez +1
We have made a study of several update algorithms using the XY model. We find that sequential local overrelaxation is not ergodic at the scale of typical Monte Carlo simulation tim…
