Can we trust semiclassical description of particle creation?
H. Nikolic
The predictions of the semiclassical description of particle creation based on QFT in classical backgrounds may be significantly modified when the source of the classical backgroun…
Black-hole information puzzle: A generic string-inspired approach
H. Nikolic
Given the insight steming from string theory, the origin of the black-hole (BH) information puzzle is traced back to the assumption that it is physically meaningful to trace out th…
Comment on "Spontaneous Inflation and the Origin of the Arrow of Time"
H. Nikolic
Recently, Carroll and Chen [hep-th/0410270] suggested a promising natural explanation of the thermodynamic arrow of time. However, we criticize their assertion that there exists a…
Fermionic functionals without Grassmann numbers
H. Nikolic
Since any fermionic operator ψcan be written as ψ=q+ip, where q and p are hermitian operators, we use the eigenvalues of q and p to construct a functional formalism for calculating…
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…
Can the Unruh-DeWitt detector extract energy from the vacuum?
H. Nikolic
The Unruh effect can be correctly treated only by using the Minkowski quantization and a model of a "particle" detector, not by using the Rindler quantization. The energy produced…
