Microscopic analysis of the superconducting quantum critical point: Finite temperature crossovers in transport near a pair-breaking quantum phase transition
N. Shah, A. V. Lopatin
A microscopic analysis of the superconducting quantum critical point realized via a pair-breaking quantum phase transition is presented. Finite temperature crossovers are derived f…
Microscopic theory of thermal phase slips in clean narrow superconducting wires
A. Zharov, A. Lopatin, A. E. Koshelev +1
We consider structure of a thermal phase-slip center for a simple microscopic model of a clean one-dimensional superconductors in which superconductivity occurs only within one con…
Granular Electronic Systems
I. S. Beloborodov, K. B. Efetov, A. V. Lopatin +1
A granular metal is an array of metallic nano-particles imbedded into an insulating matrix. Tuning the intergranular coupling strength a granular system can be transformed into eit…
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…
