Magneto-optical Conductance of Pseudospin-1 Fermionic Gas.
arXiv: Mesoscale and Nanoscale Physics(2019)
Abstract
Photon-like fermion (feroton) is the counterpart of the Weyl fermion with pseudospin-1 and can emerge in condensed matter systems. Due to the existence of a bunch of gapless modes associated with Landau levels, the magnetic transport property of feroton gas is very different from that of the Weyl semimetal. We calculate the magneto-optical conductance of the feroton gas. We find that these gapless modes will contribute to a series of resonant peaks near zero frequency. They are magnificently enhanced by a quadratic correction in the feroton spectrum. These resonant peaks also appear in the magneto-optical conductance of Kane fermion gas, the spinful feroton. Due to a quasi-one dimensional particle-hole symmetry, the magneto-optical conductance of Kane fermion is the double of the feroton. We hope these resonant phenomena would be experimentally observed in feroton materials candidates and Kane fermion materials.
