A Weyl semimetal pierced by a screw dislocation accommodates one-dimensional (1D) chiral states along the corresponding dislocation line. As these states propagate in a particular direction determined by their chirality, a persistent current (i.e....

The continuum Dirac model with an unbounded energy spectrum is widely used to describe low-energy states in various electron systems, such as graphene, topological insulators, and Weyl semimetals. However, if it is applied to analyze the electroma...

Although the Weyl model with an unbounded linear energy spectrum appropriately describes low-energy electron states in a Weyl semimetal, it cannot capture the anomalous electromagnetic response of the chiral magnetic effect (CME) and anomalous Hal...

A Weyl semimetal hosts low-energy chiral surface states, which appear to connect a pair of Weyl nodes in reciprocal space. As these chiral surface states propagate in a given direction, a spontaneous circulating current is expected to appear near ...

We report on short ballistic (SB) Josephson coupling in junctions embedded in a planar heterostructure of graphene. Ballistic Josephson coupling is confirmed by the Fabry-Perot-type interference of the junction critical current I-c. The product of...

It has been pointed out that electrons in a disordered graphene nanoribbon with zigzag edges are free from Anderson localization due to the presence of a perfectly conducting channel without backward scattering. The purpose of this research is to ...

We have studied conductance of disordered wires with symplectic symmetry at zero temperature. In the symplectic universality class, the parity of conducting channel number N plays an essential role in electron transport. In contrast to the ordinar...
