We consider interaction-induced broken symmetry states of two Weyl semimetal surfaces
with multiple Fermi-arc (FA) states. In the presence of inter-and intrasurface Coulomb …

Fermi arc states are features of Weyl semimetal (WSM) surfaces which are robust due to the
topological character of the bulk band structure. We demonstrate that Fermi arcs may …

Weyl-semimetal superstructures with a spiraling position of a pair of Weyl nodes of opposite
chirality can host a chiral-symmetry-preserving Fermi-arc metal state, where the chirality is …

We theoretically investigate the features of Ruderman-Kittel-Kasuya-Yosida (RKKY)
exchange interaction between two magnetic impurities, mediated by the interfacial bound …

In a slab geometry with large surface-to-bulk ratio, topological surface states such as Fermi
arcs for Weyl or Dirac semimetals may dominate their low-energy properties. We investigate …

The dynamics of itinerant electrons in topological insulator (TI) thin films is investigated
using a multi-band decomposition approach. We show that the electron trajectory in the 2D …
