Static properties of the dissipative random quantum Ising ferromagnetic chain
Leticia F. Cugliandolo, Gustavo S. Lozano, Homero Lozza
We study the zero temperature static properties of dissipative ensembles of quantum Ising spins arranged on periodic one dimensional finite clusters and on an infinite chain. The s…
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…
Dissipative effects on quantum glassy systems
Leticia F. Cugliandolo, Daniel Grempel, Gustavo Lozano +2
We discuss the behavior of a quantum glassy system coupled to a bath of quantum oscillators. We show that the system localizes in the absence of interactions when coupled to a subO…
