Time in relativistic and nonrelativistic quantum mechanics
H. Nikolic
The kinematic time operator can be naturally defined in relativistic and nonrelativistic quantum mechanics (QM) by treating time on an equal footing with space. The spacetime-posit…
A prediction of string theory testable at low energies
H. Nikolic
Superstring theory involves a single unifying superstring current for bosons and fermions that in the low-energy limit generalizes the Klein-Gordon (not the Dirac) current. By adop…
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…
Probability in relativistic Bohmian mechanics of particles and strings
H. Nikolic
Even though the Bohmian trajectories given by integral curves of the conserved Klein-Gordon current may involve motions backwards in time, the natural relativistic probability dens…
Unparticle as a particle with arbitrary mass
H. Nikolic
The unparticle field operator can be expanded in terms of creation and destruction operators corresponding to particles with a continuous mass spectrum. Hence, when the 4-momentum…
