Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

This review elaborates pedagogically on the fundamental concept, basic theory, expected
properties, and materials realizations of topological superconductors. The relation between …

Phases of matter are usually identified through spontaneous symmetry breaking, especially
regarding unconventional superconductivity and the interactions from which it originates. In …

Various phenomena occur when two-dimensional materials, such as graphene or transition
metal dichalcogenides, are assembled into bilayers with a twist between the individual …

Motivated by the need to understand and simulate the ubiquitous experimentally observed
zero-bias conductance peaks in superconductor-semiconductor hybrid structures, we …

The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

We show that the combination of spin-orbit coupling with a Zeeman field or strong
interactions may lead to the formation of a helical electron liquid in single-channel quantum …

Chiral superconductivity is a striking quantum phenomenon in which an unconventional
superconductor spontaneously develops an angular momentum and lowers its free energy …

Quite recently, a pronounced drop of 17O NMR Knight shift in the superconducting (SC)
state of an unstrained Sr2RuO4 was reported by Pustogow and Luo et al. They revealed …

Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …
