Quantum black-hole information missing in the semiclassical treatment
H. Nikolic
In the semiclassical treatment of gravity, an external observer can measure only the mean (not the exact) mass of the black hole (BH). By contrast, in fully quantum gravity the exa…
Renormalization of vacuum energy in linearized quantum gravity
H. Nikolic
In linearized quantum gravity, a shift of the average energy-momentum can be compensated by a shift of the average gravitational field. This allows a renormalization scheme that na…
On Cosmological Implications of Gravitational Trace Anomaly
Neven Bilic, Branko Guberina, Raul Horvat +2
We study the infrared effective theory of gravity that stems from the quantum trace anomaly. Quantum fluctuations of the metric induce running of the cosmological constant and the…
Time in quantum gravity by weakening the Hamiltonian constraint
H. Nikolic
We replace the usual Hamiltonian constraint of quantum gravity H|psi>=0 by a weaker one <psi|H|psi>=0. This allows |psi> to satisfy the time-dependent functional Schrodinger equati…
Proper co-ordinates of non-inertial observers and rotation
H. Nikolic
By proper co-ordinates of non-inertial observers (shortly - proper non-inertial co-ordinates) we understand the proper co-ordinates of an arbitrarily moving local observer. After a…
Fermi co-ordinates and relativistic effects in non-inertial frames
H. Nikolic
Fermi co-ordinates are proper co-ordinates of a local observer determined by his trajectory in space-time. Two observers at different positions belong to different Fermi frames eve…
