Asymptotic Momentum of Dirac Particles in One Space Dimension
Kabir Narayanan, Abigail Perryman, A. Shadi Tahvildar-Zadeh
We analyze the trajectories of a massive particle in one space dimension whose motion is guided by a spin-half wave function that evolves according to the free Dirac equation, with…
Noetherian Conservation Laws for Photons
Michael K. -H. Kiessling, A. Shadi Tahvildar-Zadeh
We review the formulation of a Lorentz-covariant bispinorial wave function and wave equation for a single photon on a flat background. We show the existence of a 10-dimensional set…
On the discrete Dirac spectrum of general-relativistic hydrogenic ions with anomalous magnetic moment
Elie Kapengut, Michael K. -H. Kiessling, Eric Ling +1
The Reissner-Weyl-Nordström (RWN) spacetime of a point nucleus features a naked singularity for the empirically known nuclear charges and masses , wh…
One-dimensional hydrogenic ions with screened nuclear Coulomb field
Suchindram Dasgupta, Chirag Khurana, A. Shadi Tahvildar-Zadeh
We study the spectrum of the Dirac hamiltonian in one space dimension for a single electron in the electrostatic potential of a point nucleus, in the Born-Oppenheimer approximation…
Detection time of Dirac particles in one space dimension
A. Shadi Tahvildar-Zadeh, Stephanie Zhou
We consider particles emanating from a source point inside an interval in one-dimensional space and passing through detectors situated at the endpoints of the interval that registe…
On the discrete Dirac spectrum of a point electron in the zero-gravity Kerr-Newman spacetime
Michael K. -H. Kiessling, Eric Ling, A. Shadi Tahvildar-Zadeh
The discrete spectrum of the Dirac operator for a point electron in the maximal analytically extended Kerr--Newman spacetime is determined in the zero- limit (zKN), under som…
