The wider application of spintronic devices requires the development of new material
platforms that can efficiently be used to manipulate spin. Bismuthate-based superconductors …

Superconductivity remains one of most fascinating quantum phenomena existing on a
macroscopic scale. Its rich phenomenology is usually described by the Ginzburg–Landau …

Usual superconductors fall into two categories, type I, expelling magnetic fields, and type II,
into which magnetic fields exceeding a lower critical field H c 1 penetrate in a form of …

A bstract Planar superconductors, emerging in thin films with thickness comparable to the
superconducting coherence length, differ crucially from their bulk counterparts. Coulomb …

I review a new superconductivity mechanism in which the gap is opened through a
topological mechanism and not through the Landau mechanism of spontaneous symmetry …

The four-point probe is a relatively simple method of measuring thin-layer surface resistance
using separate pairs of current-carrying and voltage-sensing contacts. This approach makes …

We show that magnetic monopoles appear naturally in granular quantum matter. Their
condensation leads to a new state of matter, superinsulation, in which Cooper pairs are …

Superinsulation is dual superconductivity. Already in the 70s, Nambu [1], Mandelstam [2]
and 't Hooft [3] proposed their model of dual superconductivity as a possible explanation of …

We review the main features of type-III superconductivity. This is a new type of
superconductivity that exists in both 2 and 3 spatial dimensions. The main characteristics are …

We systematically investigated the low-temperature transport properties of two series of NbN
epitaxial films. The first series of films with thickness ranging from∼ 2.0 to∼ 4.0 nm are two …
