Abstract
We calculated the Dirac particles' Hawking radiation from the outer horizon of BTZ black hole via tunneling formalism. Applying WKB approximation to the Dirac equation in (2+1)-dimensional BTZ spacetime background, we obtain the radiation spectrum for fermions and Hawking temperature of BTZ black hole. The results obtained by taking the fermion tunneling into account are consistent with the previous literatures.

Dirac particles tunneling from BTZ black hole
Since the Hawking radiation relates the theory of general relativity with quantum field theory and statistical thermodynamics, it is generally believed that a deeper understanding of Hawking radiation may shed some lights on seeking the underlying quantum gravity
Summary
Dirac particles tunneling from BTZ black hole We calculated the Dirac Particles’ Hawking radiation from the outer horizon of BTZ black hole via tunneling formalism. Applying WKB approximation to the Dirac equation in (2+1) dimensional BTZ spacetime background, we obtain the radiation spectrum for fermions and Hawking temperature of BTZ black hole.
