Spacetime Quantum Actions
N. L. Diaz, J. M. Matera, R. Rossignoli
We propose a formulation of quantum mechanics in an extended Fock space in which a tensor product structure is applied to time. Subspaces of histories consistent with the dynamics…

History state formalism for scalar particles
N. L. Diaz, J. M. Matera, R. Rossignoli
We present a covariant quantum formalism for scalar particles based on an enlarged Hilbert space. The particular physical theory can be introduced through a timeless Wheeler DeWitt…

History state formalism for Dirac's theory
N. L. Diaz, R. Rossignoli
We propose a history state formalism for a Dirac particle. By introducing a reference quantum clock system it is first shown that Dirac's equation can be derived by enforcing a tim…
