Bogomolny equations for vortices in the noncommutative torus
P. Forgacs, G. S. Lozano, E. F. Moreno +1
We derive Bogomolny-type equations for the Abelian Higgs model defined on the noncommutative torus and discuss its vortex like solutions. To this end, we carefully analyze how peri…

Effects of dissipation on disordered quantum spin models
L. F. Cugliandolo, D. R. Grempel, G. Lozano +1
We study the effects of the coupling to an Ohmic quantum reservoir on the static and dynamical properties of a family of disordered SU(2) spin models in a transverse magnetic field…

Non BPS noncommutative vortices
G. S. Lozano, E. F. Moreno, M. J. Rodriguez +1
We construct exact vortex solutions to the equations of motion of the Abelian Higgs model defined in non commutative space, analyzing in detail the properties of these solutions be…
