In a Dirac semimetal, the massless Dirac fermion has zero chirality ... the nonrelativistic limit of certain collinear antiferromagnets, there exists a type of chiral "Dirac-like" fermion, whose ...

Researchers have discovered an innovative way to manipulate electronic properties in a magnetic Weyl semimetal using hydrogen ...

In the presence of spin–orbit coupling and/or symmetry-breaking operations, topological nodal lines can break into Dirac/Weyl nodes and give rise to interesting transport properties, such as the ...

Rendering of the tilting of relativistic Dirac cones in ... magnetic topological semimetal achieved with insertion of hydrogen that generates tunable low-dissipation chiral charge currents.

In topological matter, Ong with Bob Cava detected (2010) surface Dirac states in the topological insulator Bi2Te3 by measuring quantum oscillations in a tilted magnetic field. In 2014, Ong and Cava ...
