A general-covariant concept of particles in curved background
H. Nikolic
A local current of particle density for scalar fields in curved background is constructed. The current depends on the choice of a two-point function. There is a choice that leads t…
Comment on "Classical interventions in quantum systems II. Relativistic invariance"
H. Nikolic
In a recent paper [Phys. Rev. A 61, 022117 (2000)], quant-ph/9906034, A. Peres argued that quantum mechanics is consistent with special relativity by proposing that the operators t…
Physical stability of the QED vacuum
H. Nikolic
The possibility of electron-positron pair creation by an electric field is studied by using only those methods in field theory the predictions of which are confirmed experimentally…
On particle production by classical backgrounds
H. Nikolic
The theory of quantum fields in classical backgrounds is re-examined for the cases in which the Lagrangian is quadratic in quantum fields. Various methods that describe particle pr…
Inappropriateness of the Rindler quantization
H. Nikolic
It is argued that the Rindler quantization is not a correct approach to study the effects of acceleration on quantum fields. First, the "particle"-detector approach based on the Mi…
Is particle creation by the gravitational field consistent with energy conservation?
H. Nikolic
If particle creation is described by a Bogoliubov transformation, then, in the Heisenberg picture, the raising and lowering operators are time dependent. On the other hand, this ti…
