Does accelerating blackhole grow in size due to constant infalling unruh radiation?
Unruh effects stipulates that an accelerating observer will observe a thermal bath, like blackbody radiation, whereas an inertial observer would observe none. Now assume a constantly accelerating ...

An example of the vacuum emitting photons?
Imagine we have two parallel wires with a potential difference of $V$ volts that form the opposite sides of a square of size $\lambda$.
Any virtual electron-positron pairs that form between the wires ...

Does an electric field cause the vacuum to emit photons?
As I understand it electron-positron pairs pop in and out of the vacuum on a time scale $T$ inversely proportional to the electron mass.
Imagine we put a static electric field across the vacuum.

Physical significance of number operator in QFT
Does the expectation value of the number operator corresponds to any physical observable or has any significance in classical limit? This is probably a dumb question, but I'm struggling to identify ...

Does the Unruh effect need the accelerating observer's Hilbert space to be smaller than the inertial one?
I've encounter two different approaches to the Unruh effect and I feel like they are not consistent with one another.
Bogoliubov Transformation
In this approach the basic statement is that the vacuum ...
