Abstract: We present a non-perturbative study of the quantum many-body effects caused by the long-range Coulomb interaction in a two-dimensional semi-Dirac semimetal. This kind of semimetal may be realized in deformed graphene and a class of… read more here.

Abstract: We theoretically investigate the electronic and transport properties of a semi-Dirac material under the influence of an external time-dependent periodic driving field (irradiation) by means of Floquet theory. We explore the inelastic scattering mechanism between… read more here.

DOI: 10.1103/physrevb.99.075415
Abstract: We show that the gap parameter in semi-Dirac material induces a large degree of sensitivity for interband optical conductivity with respect to the polarization direction. The optical conductivity reveals an abruptly large value at a… read more here.

Abstract: Within a Kubo formalism, we calculate the absorptive part of the dynamic longitudinal conductivity $\sigma(\Omega)$ of a 2D semi-Dirac material. In the clean limit, we provide separate analytic formulas for intraband (Drude) and interband contributions… read more here.
