Insulating state of granular superconductors in a strong-coupling regime
I. S. Beloborodov, Ya. V. Fominov, A. V. Lopatin +1
We analyze the possibility of the formation of a magnetic-field-induced insulating state in a two-dimensional granular superconductor with relatively strong intergranular coupling…
Thermodynamics of the superfluid dilute Bose gas with disorder
A. V. Lopatin, V. M. Vinokur
We generalize the Beliaev-Popov diagrammatic technique for the problem of interacting dilute Bose gas with weak disorder. Averaging over disorder is implemented by the replica meth…
Structural glass on a lattice in the limit of infinite dimensions
A. V. Lopatin, L. B. Ioffe
We construct a mean field theory for the lattice model of a structural glass and solve it using the replica method and one step replica symmetry breaking ansatz; this theory become…
Replica symmetry breaking in long-range glass models without quenched disorder
L. B. Ioffe, A. V. Lopatin
We discuss mean field theory of glasses without quenched disorder focusing on the justification of the replica approach to thermodynamics. We emphasize the assumptions implicit in…
Instanton approach to the Langevin motion of a particle in a random potential
A. V. Lopatin, V. M. Vinokur
We develop an instanton approach to the non-equilibrium dynamics in one-dimensional random environments. The long time behavior is controlled by rare fluctuations of the disorder p…
Barriers in the p-spin interacting spin-glass model. The dynamical approach
A. V. Lopatin, L. B. Ioffe
We investigate the barriers separating metastable states in the spherical p-spin glass model using the instanton method. We show that the problem of finding the barrier heights can…
