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…
Fractional Shapiro steps without fractional Josephson effect
Artem V. Galaktionov, Andrei D. Zaikin
It is widely believed that superconducting junctions involving topological insulators and hosting Majorana-like bound states may exhibit unusual "fractional" (-periodic) ac Jos…
Intrinsic dissipation in superconducting junctions probed by qubit spectroscopy
Dmitry S. Golubev, Artem V. Galaktionov, Andrei D. Zaikin
We propose to study frequency dependent intrinsic dissipation in a highly transparent Josephson junction by means of qubit spectroscopy. The spectral density of the effective dissi…
Andreev levels as a quantum dissipative environment
A. V. Galaktionov, D. S. Golubev, A. D. Zaikin
We argue that at subgap energies quantum behavior of superconducting weak links can be exactly accounted for by an effective Hamiltonian for a Josephson particle in a quantum dissi…
Effective action theory of Andreev level spectroscopy
Artem V. Galaktionov, Andrei D. Zaikin
With the aid of the Keldysh effective action technique we develop a microscopic theory describing Andreev level spectroscopy experiments in non-tunnel superconducting contacts. We…
Current-biased Andreev interferometer
A. V. Galaktionov, A. D. Zaikin
We theoretically investigate the behavior of Andreev interferometers with three superconducting electrodes in the current-biased regime. Our analysis allows to predict a number of…
