Condensation of slow -quanta in strong magnetic fields

Leah Folkerts, Reinhold Egger, Carsten Müller +1

The implications of the root singularity of the vacuum polarization tensor near the first pair creation threshold on blackbody radiation are investigated for magnetic fields above…

Tunneling spectroscopy of the spinon-Kondo effect in one-dimensional Mott insulators

Rodrigo G. Pereira, Bruno F. Marquez, Karen Hallberg +2

We study the tunneling density of states (TDOS) in one-dimensional Mott insulators at energies below the charge gap. By employing nonlinear Luttinger liquid theory and density-matr…

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…
