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. %K Hawking radiation %K Unruh vacuum %K Reissner-Nordstrom black holes %R 10.3390/universe10010018 %U https://arxiv.org/abs/2311.09943 %U https://doi.org/10.3390/universe10010018 %P 18 - 14pp
