Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

Superconductivity is a phenomenon where the macroscopic quantum coherence appears
due to the pairing of electrons. This offers a fascinating arena to study the physics of …

Recent works have predicted materials featuring bands with a large spin-splitting distinct
from ferromagnetic and relativistically spin-orbit-coupled systems. Materials displaying this …

Altermagnets are a new class of magnetic materials, which exhibit large spin splitting, but
due to the combined spin and real space group symmetry protection maintain zero net …

Spintronics refers commonly to phenomena in which the spin of electrons in a solid state
environment plays the determining role. In a more narrow sense spintronics is an emerging …

Recent studies on high-T c superconductors have aroused new interest in tunnelling effects
in unconventional superconductors. Unlike in conventional s-wave superconductors, the d …

Theory of dispersionless Andreev bound states on surfaces of time-reversal-invariant
unconventional superconductors is presented. The generalized criterion for the …

We study proximity-induced superconductivity on the surface of a topological insulator (TI),
focusing on unconventional pairing. We find that the excitation spectrum becomes gapless …

Electrical transport through a normal-metal/superconductor contact at biases smaller than
the energy gap can occur via the reflection of an electron as a hole of opposite wave vector …

Topological superconductors have become a subject of intense research due to their
potential use for technical applications in device fabrication and quantum information …
