# Charged fermions tunneling from stationary axially symmetric black holes with generalized uncertainty principle

## TL;DR

This paper investigates how charged fermions tunnel from various stationary axially symmetric black holes using the generalized uncertainty principle, revealing modifications to Hawking radiation and the existence of black hole remnants.

## Contribution

It introduces a GUP-based analysis of charged fermion tunneling from multiple black hole types, highlighting non-thermal spectra and black hole remnants.

## Key findings

- Modified Hawking temperature for different black holes
- Tunneling spectrum is not purely thermal due to GUP effects
- Black hole remnants are predicted as a result of minimal length scale

## Abstract

In this paper, we study the tunneling of charged fermions from the stationary axially symmetric black holes using the generalized uncertainty principle (GUP) via Wentzel, Kramers, and Brillouin (WKB) method. The emission rate of the charged fermions and corresponding modified Hawking temperature of Ker-Newman black hole, Einstein-Maxwell-Dilaton-Axion (EMDA) black hole, Kaluza-Klein dilaton black hole, and then, charged rotating black string are obtained and we show that the corrected thermal spectrum is not purely thermal because of the minimal scale length which cause the black hole's remnant.
