Hermitian Dirac Hamiltonian in time dependent gravitational field
M. Leclerc
It is shown by a straightforward argument that the Hamiltonian generating the time evolution of the Dirac wave function in relativistic quantum mechanics is not hermitian with resp…
Intrinsic momentum in Poincare gauge theory
M. Leclerc
While it is generally accepted, in the framework of Poincare gauge theory, that the Lorentz connection couples minimally to spinor fields, there is no general agreement on the coup…
Canonical and gravitational stress-energy tensors
M. Leclerc
It is dealt with the question, under which circumstances the canonical Noether stress-energy tensor is equivalent to the gravitational (Hilbert) tensor for general matter fields un…
One-parameter teleparallel limit of Poincare gravity
M. Leclerc
Poincare gauge theories that, in the absence of spinning matter, reduce to the one-parameter teleparallel theory are investigated with respect to their mathematical consistency and…
Second order formalism in Poincare gauge theory
M. Leclerc
Changing the set of independent variables of Poincare gauge theory and considering, in a manner similar to the second order formalism of general relativity, the Riemannian part of…
Mathisson-Papapetrou equations in metric and gauge theories of gravity in a Lagrangian formulation
M. Leclerc
We present a simple method to derive the semiclassical equations of motion for a spinning particle in a gravitational field. We investigate the cases of classical, rotating particl…
The Higgs sector of gravitational gauge theories
M. Leclerc
Gravitational gauge theories with de Sitter, Poincare and affine symmetry group are investigated under the aspect of the breakdown of the initial symmetry group down to the Lorentz…
