On the two aspects of time: The distinction and its implications
The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the pastExpand
Off-shell electromagnetism in manifestly covariant relativistic quantum mechanics
Gauge invariance of a manifestly covariant relativistic quantum theory with evolution according to an invariant time τ implies the existence of five gauge compensation fields, which we shall callExpand
On relativistic quantum theory for particles with spin 1/2
The authors study a family of Hilbert spaces with positive definite invariant scalar product for the quantum mechanical description of relativistic spin-1/2 particles. The Hermitian andExpand
Lorentz transformation on the lattice
We study the possibility of representing the kinematical variables of a free particle in terms of scale factors and integers. The action of a set of transformations from the Lorentz groupExpand
The quantum relativistic two‐body bound state. I. The spectrum
In the framework of a manifestly covariant quantum theory on space‐time, it is shown that the ground state mass of a relativistic two‐body system with O(3,1) symmetric potential is lower whenExpand
The quantum relativistic two‐body bound state. II. The induced representation of SL(2,C)
It was shown in I [J. Math. Phys. 30, 66 (1989)] that the eigenfunctions for the reduced motion of the quantum relativistic bound state with O(3,1) symmetric potential have support in an O(2,1)Expand
Covariant phase shift analysis for relativistic potential scattering
Abstract We derive a partial wave expansion for two-body relativistic processes (with explicit relativistic corrections) in the framework of a manifestly covariant relativistic quantum theory. As anExpand
Selection rules for dipole radiation from a relativistic bound state
Recently, in the framework of a relativistic quantum theory with invariant evolution parameter, solutions have been found for the two-body bound state, whose mass spectrum agrees with theExpand
The Landau-Peierls relation and a causal bound in covariant relativistic quantum theory
Thought experiments analogous to those discussed by Landau and Peierls are studied in the framework of a manifestly covariant relativistic quantum theory. It is shown that momentum and energy can beExpand
