PY - 2024 DA - 2024// TI - The Unruh Vacuum and the "In-Vacuum" in Reissner-Nordström Spacetime T2 - Universe JO - Universe SP - 18 - 14pp VL - 10 IS - 1 PB - Mdpi KW - Hawking radiation KW - Unruh vacuum KW - Reissner-Nordstrom black holes AB - The Unruh vacuum is widely used as a quantum state to describe black hole evaporation since, near the horizon, it reproduces the physical state of a quantum field, the so-called "in-vacuum", in the case where a black hole is formed by gravitational collapse. We examine the relation between these two quantum states in the background spacetime of a Reissner-Nordstrom black hole (both extremal and not), highlighting the similarities and striking differences.
