Hopping Transport in Granular Superconductors
A. V. Lopatin, V. M. Vinokur
We study the conductivity of granular superconductors in the weak coupling insulating regime. We show that it is governed by the hopping of either electrons or Cooper pairs dependi…
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…
Low temperature magnetoresistance of dirty thin films and quantum wires near a parallel-field-tuned superconducting quantum phase transition
N. Shah, A. V. Lopatin, V. M. Vinokur
We study the low temperature magnetoresistance of dirty thin films and quantum wires close to a quantum phase transition from a superconducting to normal state, induced by applying…
Effective description of hopping transport in granular metals
I. S. Beloborodov, A. V. Lopatin, V. M. Vinokur +1
We develop a theory of a variable range hopping transport in granular conductors based on the sequential electron tunnelling through many grains in the presence of the strong Coulo…
