Magnetic Bloch bands and Weiss oscillations in Dirac mass superlattices
A. Anand, R. Egger, A. De Martino
We study two-dimensional Dirac fermions in a one-dimensional mass superlattice under a perpendicular magnetic field. Using exact solutions for isolated and finite arrays of domain…

Magnetic-field-tunable anisotropic blackbody radiation and condensation of slow thermal light in dynamical axion insulators
Eric Kochems, Gretel Quintero Angulo, Reinhold Egger +2
Thermal radiation features of dynamical axion insulators, which are characterized by an antiferromagnetic order with simultaneously broken time-reversal and space-inversion symmetr…

Quantum description of Fermi arcs in Weyl semimetals in a magnetic field
Tim Bauer, Francesco Buccheri, Alessandro De Martino +1
For a Weyl semimetal (WSM) in a magnetic field, a semiclassical description of the Fermi-arc surface state dynamics is usually employed for explaining various unconventional magnet…
