Erratum: Magnetoresistance of a three-dimensional Dirac gas [Phys. Rev. B 98, 195420 (2018)]

Figure 11

Transverse diagonal conductivity ${\sigma }_{xx}$ calculated from Eq. (52) as a function of magnetic field at different temperatures. $\mathrm{\Delta }=0$ (top plot) and $\mathrm{\Delta }=2/{\ell }_{1\mathrm{T}}$ (bottom plot). The scattering rate is chosen phenomenologically based on the numerical results in Fig. 8. The inset shows the scattering rates used (no Landau-level dependence is assumed). $T_0=0,T_1=50\mathrm{K}$, the density of charge carriers is $n_e={10}^{18}{\mathrm{cm}}^{-3}$, and ${\sigma }_0/{\ell }_{1\mathrm{T}}\approx 15{\mathrm{\Omega }}^{-1}{\mathrm{cm}}^{-1}$.

Figure 12

Transverse diagonal conductivity ${\sigma }_{xx}$ calculated from Eq. (52) as a function of magnetic field at zero temperature. $\mathrm{\Delta }=0$ (top plot) and $\mathrm{\Delta }=2/{\ell }_{1\mathrm{T}}$ (bottom plot). The scattering rate is calculated using Eq. (46a) using screening wave numbers calculated through Eq. (41). The inset shows the scattering rates used $(n=1$ Landau level). The density of charge carriers is $n_e={10}^{18}{\mathrm{cm}}^{-3}$, and ${\sigma }_0/{\ell }_{1\mathrm{T}}\approx 15{\mathrm{\Omega }}^{-1}{\mathrm{cm}}^{-1}$.

Figure 13

Magnetoresistance ${\varrho }_{xx}$ calculated from Eq. (56) as a function of magnetic field. $\mathrm{\Delta }=0$ (top panel) and $\mathrm{\Delta }=2/{\ell }_{1\mathrm{T}}$ (bottom panel). The resistivity calculated from the phenomenological result (red line) and the resistivity calculated microscopically using the first Born approximation with $\varepsilon =1$ (blue). The density of charge carriers is $n_e={10}^{18}{\mathrm{cm}}^{-3}$, and ${\sigma }_0/{\ell }_{1\mathrm{T}}\approx 15{\mathrm{\Omega }}^{-1}{\mathrm{cm}}^{-1}$.
