Superconducting Proximity Effect in an SSH-Superconductor Junction
I. A. Belkovich, A. A. Radkevich
A model of microscopic interaction between a superconductor and a one-dimensional topological insulator, an SSH chain, is considered. Using the functional integration method, the e…
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 insulators and localization of Cooper pairs
Konstantin Yu. Arutyunov, Janne S. Lehtinen, Alexey Radkevich +2
Rapid miniaturization of electronic devices and circuits demands profound understanding of fluctuation phenomena at the nanoscale. Superconducting nanowires -- serving as important…
Topology controlled phase coherence and quantum fluctuations in superconducting nanowires
Alexey Radkevich, Andrew G. Semenov, Andrei D. Zaikin
Superconducting properties of metallic nano-wires may strongly depend on specific experimental conditions. Here we consider a setup where superconducting phase fluctuations are res…
Quantum fluctuations and phase coherence in superconducting nanowires
Alexey Radkevich, Andrew G. Semenov, Andrei D. Zaikin
Quantum behavior of superconducting nanowires may essentially depend on the employed experimental setup. Here we investigate a setup that enables passing equilibrium supercurrent a…
Quantum phase fluctuations and density of states in superconducting nanowires
Alexey Radkevich, Andrew G. Semenov, Andrei D. Zaikin
We argue that quantum fluctuations of the phase of the order parameter may strongly affect the electron density of states (DOS) in ultrathin superconducting wires. We demonstrate t…
