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…
Bohmian particle trajectories in relativistic bosonic quantum field theory
H. Nikolic
We study the de Broglie-Bohm interpretation of bosonic relativistic quantum mechanics and argue that the negative densities and superluminal velocities that appear in this interpre…
Generalizations of normal ordering and applications to quantization in classical backgrounds
H. Nikolic
A nonlocal method of extracting the positive (or the negative) frequency part of a field, based on knowledge of a 2-point function, leads to certain natural generalizations of the…
The general-covariant and gauge-invariant theory of quantum particles in classical backgrounds
H. Nikolic
A new approach to the concept of particles and their production in quantum field theory is developed. A local operator describing the current of particle density is constructed for…
