We review results on two novel types of grain boundary Josephson junctions in the high critical temperature cuprate superconductors. The quality of YBa₂Cu₃O₇-δ biepitaxial grain boundary Josephson junctions have been ...

For certain orientations of Josephson junctions between two px-wave or two d-wave superconductors, the subgap Andreev bound states produce a 4π-periodic relation between the Josephson current I and the phase difference:φ ...

We implement the impedance measurement technique (IMT) for characterization of interferometer- type superconducting qubits. In the framework of this method, the interferometer loop is inductively coupled to a high-quality ...

We study the dynamics of a single spin embedded in the tunneling barrier between two superconductors. As a consequence of pair correlations in the superconducting state, the spin displays rich and unusual dynamics. To ...

The modern physics of superconductivity can be called the physics of unconventional superconductivity. The discovery of the d-wave symmetry of the order parameter in high-temperature superconductors and the triplet ...

We review recent results on a new class of Josephson arrays which have non-trivial topology and exhibit a novel quantum states at low temperatures. One of these states is characterized by long range order in a two Cooper ...

A technique for studying collisionless dynamics of a homogeneous superconducting system is developed which is based on Riccati parametrization of the Wigner distribution function. The quantum evolution of the superconducting ...

Приведены результаты экспериментальных исследований магнитного отклика монокристаллов YBa₂Cu₃O₇–x, имеющих однонаправленные плоскости двойникования, в слабых постоянных магнитных полях. Наблюдаемая немонотонность ...

Представлен обзор результатов исследований электронного транспорта в тонкопленочных гетеропереходах Au/YBa₂Cu₃Ox и Nb/Au/YBa₂Cu₃Ox. В ток-фазовых зависимостях гетеропереходов Nb/Au/YBa₂Cu₃Ox на с-ориентированных пленках ...
