Abstract:
We consider experimental and theoretical studies of Ising superconductivity. This new field in the physics of superconductivity was given impetus by the discovery of unusual properties in layered molybdenum disulfide ($\rm MoS_2$) exhibiting an unprecedentedly high upper critical magnetic field $B_{\rm c2}$, exceeding the paramagnetic Pauli limit six fold. It turns out that this is due to the properties of the crystal lattice of two-dimensional monolayers inducing Ising and Rashba spin–orbit coupling. Features of the crystal structure lead to a possible coexistence of singlet and triplet pairing and to the emergence of topological phases. Some options for searching for the Majorana fermion formations at the ends of long one-dimensional wires on the surface of an Ising superconductor are discussed.
Keywords:layered structures with triangular layers, Ising spin–orbit coupling, Rashba spin–orbit coupling, singlet and triplet Cooper pairs, topological states
