Impurity-induced Inverse Faraday Effect
A. A. Kopasov, A. A. Bespalov, A. S. Mel'nikov
We provide a quantum-mechanical description of the photoinduced dc current states and magnetic fields around nonmagnetic point impurities in a two-dimensional (2D) electron gas irr…
Strongly nonlinear regime of Josephson transmission lines revealed by two-tone spectroscopy
A. S. Averkin, A. A. Kopasov, I. E. Pologov +5
We present experimental and theoretical studies of the off-resonant and strongly nonlinear regime of Josephson transmission lines (JTLs) with galvanically-coupled nonlinear element…
Interplay of ferroelectricity and interlayer superconductivity in van der Waals bilayers
D. S. Annenkov, A. A. Kopasov, A. S. Mel'nikov
We study the distinctive features of the interplay between the interlayer superconductivity and ferroelectricity in van der Waals heterostructures. Corresponding analysis is carrie…
Proximity Induced Non-collinear Magnetic States in Planar Superconductor/Ferromagnet Hybrids
A. A. Kopasov, S. V. Mironov, A. S. Mel'nikov
The proximity induced superconducting (S) correlations in ferromagnetic (F) layers of planar S/F hybrids are shown to be responsible for the appearance of a nonlinear interaction b…
Adiabatic phase pumping in S/F/S hybrids with non-coplanar magnetization
A. A. Kopasov, Zh. Devizorova, H. Meng +3
We study the distinctive features of the phase pumping effect in Josephson transport through a three-layered ferromagnet F/F/F with non-coplanar magnetization. Using Gor'ko…
Unconventional superconductivity and paramagnetic Meissner response triggered by nonlocal pairing interaction in proximitized heterostructures
A. A. Kopasov, A. S. Mel'nikov
Proximity phenomena and induced superconducting correlations in heterostructures are shown to be strongly affected by the nonlocal nature of the electronic attraction. The latter c…
