“…The temperature obtained, exactly matches with the literature in different contexts, using, for example, the Bogoliubov transformations. This formalism can also be applied for some other curved spacetime such as Reissner-Nordstrom-de Sitter [51][52][53][54][55], Reissner-Nordstrom-Antide Sitter [56,57], Kerr-de Sitter [58,59], Kerr-Antide Sitter [60,61], Kerr-Newman-de Sitter [62][63][64], and Kerr-Newman-Anti-de Sitter spacetimes [65,66].…”

Generalizing to relativistic exponential scaling and using the theory of noise from quantum fluctuations, it has been shown that one vacuum (Rindler, Hartle-Hawking, or Gibbons-Hawking for the cases of the uniformly accelerated detector, black hole, and de-Sitter universe, respectively) can be understood as resulting from the scaling of quantum noise in another vacuum. We explore this idea more generally to establish a flat spacetime and curved spacetime analogy. For this purpose, we start by examining noise kernels for free fields in some well-known curved spacetimes, e.g., the spacetime of a charged black hole, the spacetime of a Kerr black hole, Schwarzschild-de Sitter, and Schwarzschild anti-de Sitter spacetimes. Here, we consider a maximal analytical extension for all these spacetimes. We show that the exponential scale transformation is responsible for the thermal nature of radiation.
