Measuring correlations using local and nonlocal quenches
Alexey G. Mikhaylenko, Andrew G. Semenov
We present a theoretical proposal for measuring correlation functions in a quantum field system based on the use of quantum quenches. Using the examples of massive and massless sca…
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…
Comment on the paper SciPost Phys. Core 6, 019 (2023) by João F. Melo (arXiv:2112.09119)
Anna Radovskaya, Andrew G. Semenov
In the paper by João F. Melo "The propagator matrix reloaded" (SciPost Phys. Core 6, 019 (2023), arXiv:2112.09119) the author provides a derivation of a formalism which includes in…
Nonlinear microwave response of clean superconducting films
A. A. Radkevich, A. G. Semenov
We develop an explicitly gauge-invariant semiclassical approach to investigate nonlinear response of superconductors to monochromatic THz radiation. We demonstrate that in clean su…
Superconducting quantum fluctuations in one dimension
Andrew G. Semenov, Andrei D. Zaikin
We review some recent developments in the field of quasi-one-dimensional superconductivity. We demonstrate that low temperature properties of superconducting nanowires are essentia…
