Sputtered NbN Films for Ultrahigh Performance Superconducting Nanowire Single-Photon Detectors
Ilya A. Stepanov, Aleksandr S. Baburin, Danil V. Kushnev +7
Nowadays ultrahigh performance superconducting nanowire single-photon detectors are the key elements in a variety of devices from biological research to quantum communications and…
Superconductivity and spin density wave in AA stacked bilayer graphene
A. O. Sboychakov, A. L. Rakhmanov, A. V. Rozhkov
This work theoretically analyzes electronic ordering in AA-stacked bilayer graphene and the role of the Coulomb interaction in these many-body phenomena. Using the random phase app…
Coexistence of nematic superconductivity and spin density wave in magic-angle twisted bilayer graphene
A. O. Sboychakov, A. V. Rozhkov, A. L. Rakhmanov
We argue that doped twisted bilayer graphene with magical twist angle can become superconducting. In our theoretical scenario, the superconductivity coexists with the spin-density-…
Triplet superconductivity and spin density wave in biased AB bilayer graphene
A. O. Sboychakov, A. V. Rozhkov, A. L. Rakhmanov
We examine spin density wave and triplet superconductivity as possible ground states of the Bernal bilayer graphene. The spin density wave is stable for the unbiased and undoped bi…
Interaction between spin and Abrikosov vortices in doped topological insulators
A. V. Kapranov, R. S. Akzyanov, A. L. Rakhmanov
In the topological superconductor with the nematic superconductivity in representation, it is possible to have different types of vortices. One is associated with the vortici…
Anomalous Josephson Hall effect in doped topological insulators with the nematic superconductivity
R. S. Akzyanov, A. L. Rakhmanov
We study the physics of the Josephson effect in nematic superconductors with odd parity in the Ginzburg-Landau approach. Two-component vector superconducting order parameter…
