Fermion Fields in BTZ Black Hole Space-Time and Entanglement Entropy

الملخص EN

We study the entanglement entropy of fermion fields in BTZ black hole space-time and calculate prefactor of the leading and subleading terms and logarithmic divergence term of the entropy using the discretized model.

The leading term is the standard Bekenstein-Hawking area law and subleading term corresponds to first quantum corrections in black hole entropy.

We also investigate the corrections to entanglement entropy for massive fermion fields in BTZ space-time.

The mass term does not affect the area law.
