Dissipative quantum mechanics of Andreev bound states
Mikhail S. Kalenkov, Andrei D. Zaikin
We propose a microscopic scheme that allows to describe ac Josephson effect in superconducting junctions in terms of dissipative quantum dynamics of subgap Andreev bound states. Th…
Landau-Zener tunneling and quantum interference of Andreev states
Mikhail S. Kalenkov, Andrei D. Zaikin
With the aid of a microscopic theory we derive an effective Hamiltonian that controls quantum dynamics of Andreev states in superconducting nanojunctions out of equilibrium. Resolv…
Fluxon cotunneling in coupled Josephson junctions: Perturbation theory
Andrew G. Semenov, Alex Latyshev, Andrei D. Zaikin
We investigate the effects of fluxon cotunneling and quantum Coulomb drag in a system of two small Josephson junctions coupled by means of mutual capacitance . Depending on th…
Quantum Coulomb drag mediated by cotunneling of fluxons and Cooper pairs
Andrew G. Semenov, Alex Latyshev, Andrei D. Zaikin
We predict two novel quantum drag effects which can occur in macroscopically quantum coherent Josephson circuits. We demonstrate that biasing one resistively shunted Josephson junc…
Absence of "fractional ac Josephson effect" in superconducting junctions
Mikhail S. Kalenkov, Andrei D. Zaikin
We develop a microscopic theory of ac Josephson effect in superconducting junctions described by an arbitrary scattering matrix that may include magnetic effects. In the limit of c…
Josephson dynamics at high transmissions: Perturbation theory
Artem V. Galaktionov, Andrei D. Zaikin
We theoretically analyze Josephson dynamics of superconducting weak links with transmissions not much smaller than unity at subgap bias voltages . Employing the e…
