Principal transport properties of α-T<sub>3</sub> model in the presence of external irradiation.
POSTER
Abstract
Using a simplified s-wave approximation approach for the conventional Boltzmann conductivity
equation, we have obtained the transport properties of pseudospin-1 electrons in the α-T3 lattice
irradiated by external light with linear or circular polarization. Basic transport properties of such
dressed states significantly depend on their low-energy band structure and the corresponding wave
functions. These electronic states are mainly determined by the polarization of the incident dressing
field. For instance, circularly-polarized radiation leads to opening an energy gap, which could
substantially suppress the conductivity. Electron transport also shows dependence on the coupling
strength parameter α of an α-T3 lattice, which has also been thoroughly investigated.
