The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

The importance of global band topology is unequivocally recognized in condensed matter
physics, and new states of matter, such as topological insulators, have been discovered …

We propose heterostructures that realize first and second order topological
superconductivity with vanishing net magnetization by utilizing altermagnetism. Such …

Majorana fermion is a hypothetical particle that is its own antiparticle. We report transport
measurements that suggest the existence of one-dimensional chiral Majorana fermion …

Exotic massless fermionic excitations with nonzero Berry flux, other than the Dirac and Weyl
fermions, could exist in condensed matter systems under the protection of crystalline …

The chiral Majorana fermion is a massless self-conjugate fermion which can arise as the
edge state of certain 2D topological matters. It has been theoretically predicted and …

A quantum anomalous Hall (QAH) insulator coupled to an s-wave superconductor is
predicted to harbor chiral Majorana modes. A recent experiment interprets the half …

Topological states of quantum matter have been investigated intensively in recent years in
materials science and condensed matter physics. The field developed explosively largely …

The quantum anomalous Hall effect (QAHE) is a quantized Hall effect that occurs at zero
magnetic field. Its mechanism and properties are different from those of conventional …

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