Inverse Symmetry Breaking on the lattice: an accurate MC study
G. Bimonte, D. Iniguez, A. Tarancon +1
We present here a new MC study of ISB at finite temperature in a model in four dimensions. The results of our simulations, even if not conclusive, are favour…
A Monte Carlo study of Inverse Symmetry Breaking
G. Bimonte, D. Iñiguez, A. Tarancón +1
We make a Monte Carlo study of the coupled two-scalar model in four dimensions at finite temperature. We find no trace of Inverse Symmetry Breaking for values of the…
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 lattice Monte Carlo study of Inverse Symmetry Breaking in a two-scalar model in three dimensions
G. Bimonte, D. Iñiguez, A. Tarancón +1
We carry a Monte Carlo study of the coupled two-scalar model in three dimensions. We find no trace of Inverse Symmetry Breaking in the region of negative 's for w…
Continuum limit of finite temperature from lattice Monte Carlo
G. Bimonte, D. Iñiguez, A. Tarancón +1
The model at finite temperature is simulated on the lattice. For fixed we compute the transition line for by means of Finite Size Scaling techniques.…
Antiferromagnetism in four dimensions: search for non-triviality
J. L. Alonso, H. G. Ballesteros, I. Campos +8
We present antiferromagnetism as a mechanism capable of modifying substantially the phase diagram and the critical behaviour of statistical mechanical models. This is particularly…
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…
Phase diagram of d=4 Ising Model with two couplings
J. L. Alonso, J. M. Carmona, J. Clemente Gallardo +4
We study the phase diagram of the four dimensional Ising model with first and second neighbour couplings, specially in the antiferromagnetic region, by using Mean Field and Monte C…
The Coulomb-Higgs transition of the three-parameter U(1)-Higgs model
A. Cruz, D. Iniguez, A. Tarancon +2
We find a first order Coulomb--Higgs phase transition at moderately large values of the coupling , and no evidence for a change of order at any finite value of it.
Instanton-like Contributions to the Dynamics of Yang-Mills Fields on the Twisted Torus
The RTN Collaboration, Garcia Perez, Gonzalez-Arroyo +16
We study lattice gauge theory in small volumes and with twist . We investigate the presence of the periodic instantons of and determine the…
The U(1)-Higgs Model: Critical Behaviour in the Confinig-Higgs region
Alonso, Azcoiti, Campos +15
We study numerically the critical properties of the U(1)-Higgs lattice model, with fixed Higgs modulus, in the region of small gauge coupling where the Higgs and Confining phases m…
