Fractional Power-Law Intraband Optical Conductivity in the Low-Dimensional Dirac Material CaMnBi<sub>2</sub>
We studied the broadband optical conductivity of CaMnBi<sub>2</sub>, a material with two-dimensional Dirac electronic bands, and found that both components of the intraband conductivity follow a universal power law as a function of frequency at low temperatures. This conductivity scaling...
