A Relativistic Version of the Two-Level Atom in the Rest-Frame Instant Form of Dynamics
David Alba, Horace W. Crater, Luca Lusanna
We define a relativistic version of the two-level atom, in which an extended atom is replaced by a point particle carrying suitable Grassmann variables for the description of the t…
Massless Particles plus Matter in the Rest-Frame Instant Form of Dynamics
David Alba, Horace W. Crater, Luca Lusanna
After introducing the parametrized Minkowski theory describing a positive-energy scalar massless particle, we study the rest-frame instant form of dynamics of such a particle in pr…
The Rest-Frame Instant Form and Dirac Observables for the Open Nambu String
D. Alba, H. W. Crater, L. Lusanna
The rest-frame instant form of the positive-energy part of the open Nambu string is developed. The string is described as a decoupled non-local canonical non-covariant Newton-Wigne…
Relativistic Quantum Mechanics and Relativistic Entanglement in the Rest-Frame Instant Form of Dynamics
David Alba, Horace Crater, Luca Lusanna
A new formulation of relativistic quantum mechanics is proposed in the framework of the rest-frame instant form of dynamics with its instantaneous Wigner 3-spaces and with its desc…
Towards Relativistic Atomic Physics. I. The Rest-Frame Instant Form of Dynamics and a Canonical Transformation for a System of Charged Particles plus the Electro-Magnetic Field
David Alba, Horace Crater, Luca Lusanna
A complete exposition of the rest-frame instant form of dynamics for arbitrary isolated systems (particles, fields, strings, fluids)admitting a Lagrangian description is given. The…
Hamiltonian Relativistic Two-Body Problem: Center of Mass and Orbit Reconstruction
David Alba, Horace W. Crater, Luca Lusanna
After a short review of the history and problems of relativistic Hamiltonian mechanics with action-at-a-distance inter-particle potentials, we study isolated two-body systems in th…
