Modification of the right-hand-side of canonical commutation relations (CCR) naturally occurs if one considers a harmonic oscillator with indefinite frequency. Quantization of electromagnetic field by means of such a non-CCR algebra naturally removes the infinite energy of vacuum but still results in a theory which is very similar to quantum electrodynamics. An analysis of perturbation theory shows that the non-canonical theory has an automatically built-in cut-off but requires charge/mass… 

A solvable model of interacting photons

It is a general belief that the relevant models of quantum field theory cannot be solved analytically. It is even not clear how to formulate these models in a mathematically consistent manner. Only

Regularization as Quantization in Reducible Representations of CCR

A covariant quantization scheme employing reducible representations of canonical commutation relations with positive-definite metric and Hermitian four-potentials (an alternative to the Gupta-Bleuler

Automatic Regularization by Quantization in Reducible Representations of CCR: Point-Form Quantum Optics with Classical Sources

Electromagnetic fields are quantized in a manifestly covariant way by means of a class of reducible “center-of-mass N-representations” of the algebra of canonical commutation relations (CCR). The

The question is discussed whether the momentum of a photon has a quantum uncertainty or whether it is a classical quantity. The latter assumption is the main characteristic of reducible Quantum

Quantization of free electromagnetic field: A different approach to the time-like polarization

A four-dimensional photon polarization space, such that gives a different interpretation of the ladder operators for the time-like degree comparing to the Gupta-Bleuler formulation is presented. This

Emergent Coulomb Forces in Reducible Quantum Electrodynamics

This paper discusses an attempt to develop a mathematically rigorous theory of quantum electrodynamics (QED). It deviates from the standard version of QED mainly in two aspects: it is assumed that

Reducible representations of CAR and CCR with possible applications to field quantization

Reducible representations of CAR and CCR are applied to second quantization of Dirac and Maxwell fields. The resulting field operators are indeed operators and not operator-valued distributions.

Relativistic EPR-type experiments for photons in the background of reducible representation HOLA algebras

Experiments are discussed here in which this entanglement results from the elastic scattering of a photon from an atom initially in a state with extended spatial coherence inside an atom interferometer.

An intense, pure beam of sodium molecules (Na2) is produced by using light forces to separate the atomic and molecular species in a seeded supersonic beam using diffraction from a microfabricated grating and a molecule interferometer with fully separated beams and high contrast fringes.

In the Wigner formalism, after giving a general description of a light beam, the theory of parametric down-conversion is developed to second-order in the coupling constant. We then describe the

Observation of Interference Between Two Bose Condensates

It is demonstrated that Bose condensed atoms are “laser-like”; that is, they are coherent and show long-range correlations and have direct implications for the atom laser and the Josephson effect for atoms.
