Quantum Tunneling Radiation of Reissner-Nordstrom de Sitter Black Hole with a Global Monopole

摘要

Applying Parikh's quantum tunneling model, we study the quantum tunneling radiation of Reissner-Nordstrom de Sitter black hole with a global monopole. The result shows that the tunneling rates at tie event horizon and the cosmic horizon are related to Bekenstein-Hawking entropy if we take the energy conservation into consideration, and the true radiate spectrum is not precisely thermal.
