Hawking radiation from a BTZ black hole viewed as Landauer transport
  Viewing Hawking radiation as a 1D single quantum channel Landauer transport process, Nation et al calculated the energy flux and entropy flux from a Schwarzschild black hole without chemical potential. To generalize the method to the case with chemical potential, a rotating charged and non-charged BTZ black hole is investigated. Energy flux and entropy flux obtained are consistent with that from anomaly theory. The maximum energy flux and entropy flux are independent on the statistics of bosons or fermions.
