Axionic Acoustic Phonons from Weyl Semimetals
Joan Bernabeu, Alberto Cortijo
The sound propagation properties resulting from a dynamical axion insulator generated from a Weyl semimetal are explored. Due to the axial electron-phonon coupling, the speed of so…

Bulk Hydrodynamic Transport in Weyl Semimetals
Joan Bernabeu, Kitinan Pongsangangan, H. T. C. Stoof +1
The role of collective longitudinal modes, plasmons, in bulk hydrodynamic transport in Weyl semimetals is explored. In contrast to graphene, where these modes are gapless, plasmons…

Hysteresis of Axionic Charge Density Waves
Joan Bernabeu, Alberto Cortijo
Magnetic Catalysis is a known proposal for inducing dynamical axionic gapped phases by means of external magnetic fields from a Weyl or Dirac semimetal phase. At finite Fermi level…
