New advances in numerical simulations of theta-vacuum systems
V. Azcoiti, G. Di Carlo, A. Galante +1
We proposed two different methods for simulating theta-vacuum systems. Both can be affected by systematic effects but these errors can be controlled by comparing the results of the…
Diquark condensation at strong coupling
V. Azcoiti, G. Di Carlo, A. Galante +1
The possibility of diquark condensation at sufficiently large baryon chemical potential and zero temperature is analyzed in QCD at strong coupling. In agreement with other strong c…
Theta dependence of CP^9 model
V. Azcoiti, G. Di Carlo, A. Galante +1
We apply to the model two recently proposed numerical techniques for simulation of systems with a theta term. The algorithms, successfully tested in the strong coupling limi…
Theta-vacuum: Phase Transitions and/or Symmetry Breaking at
V. Azcoiti, A. Galante, V. Laliena
Assuming that a quantum field theory with a -vacuum term in the action shows non-trivial -dependence and provided that some reasonable properties of the probability distribut…
Theta-vacuum systems via real action simulations
V. Azcoiti, G. Di Carlo, A. Galante +1
Inspired by the results of the Ising model within an imaginary external magnetic field, we introduce a transformation in quantum systems with a theta-vacuum term that amounts to a…
