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

We review theoretical and experimental highlights in transport in two-dimensional
topological materials over the last five years. Topological materials comprise topological …

We show from a weak-coupling microscopic calculation that the most favored chiral
superconducting order parameter in Sr 2 RuO 4 has a Chern number of| C|= 7. The two …

Sr 2 RuO 4 is one of the most promising candidates of a topological superconductor with
broken time-reversal symmetry because a number of experiments have revealed evidence …

We study the mechanism of the triplet superconductivity (TSC) in Sr 2 RuO 4 based on the
multiorbital Hubbard model. The electronic states are studied using the recently developed …

We study surface zero-energy flat bands in three-dimensional chiral superconductors with
pz (px+ ipy) ν-wave pairing symmetry (ν is a nonzero integer), based on topological …

The superconducting pairing in Sr 2 RuO 4 is widely considered to be chiral p wave with d→
k∼(kx+ iky) z^, which belongs to the E u representation of the crystalline D 4 h group …

We present a theory of the dc Josephson effect in contacts between Fe-based and spin-
singlet s-wave superconductors. The method is based on the calculation of temperature …

We study the surface Andreev bound states (SABSs) and quasiparticle tunneling
spectroscopy of three-dimensional (3D) chiral superconductors by changing their surface …

We examine the tunneling spectroscopy of three-dimensional normal-metal/Sr 2 RuO 4
junctions as an experimental means to identify pairing symmetry in Sr 2 RuO 4. In particular …
