Sažetak (engleski)
The current-dipole conductivity formula for doped three-dimensional Dirac semimetals is derived by using a modified gauge-invariant tight-binding approach. In a heavily doped regime, the effective number of charge carriers neff alpha alpha in the Drude contribution is found to be by a factor of 4 larger than the nominal electron concentration n. However, its structure is the same as in standard Fermi liquid theory. In a lightly doped regime, on the other hand, the ratio neff alpha alpha/n is much larger, with much more complex structure of neff alpha alpha. It is shown that the dc resistivity and reflectivity date measured in two TlBiSSe samples can be easily understood, even in the relaxation-time approximation, provided that finite quasiparticle lifetime effects in the momentum distribution functions are properly taken into account.
