Quantum distributions for the electromagnetic field

چکیده
The coherence properties of the classical waves are discussed in terms Cauchy problem for wave equation, and a discrete representation by an ensemble Hamiltonian systems. Wave quanta related to specific "action fields", phase-space distributions phonons photons obtained Wigner transform. For thermal environment, proposed function evolves towards Planck equilibrium distribution. It is shown that free electromagnetic field can also be found states definite helicity, described complex vector potential.

On the physical realizability of highly focused electromagnetic field distributions.
A method to evaluate the physical realizability of an arbitrary three-dimensional vectorial field distribution in the focal area is proposed. A parameter that measures the similarity between the designed (target) field and the physically achievable beam is provided. This analysis is carried out within the framework of the closest electromagnetic field to a given vectorial function, and the proc...
متن کاملImaging Nanoscale Electromagnetic Near-Field Distributions Using Optical Forces
We demonstrate the application of Atomic Force Microscopy (AFM) for mapping optical near-fields with nanometer resolution, limited only by the AFM probe geometry. By detecting the optical force between a gold coated AFM probe and its image dipole on a glass substrate, we profile the electric field distributions of tightly focused laser beams with different polarizations. The experimentally reco...
متن کاملQuantum and classical statistics of the electromagnetic zero-point field.
A classical electromagnetic zero-point field ~ZPF! analog of the vacuum of quantum field theory has formed the basis for theoretical investigations in the discipline known as random or stochastic electrodynamics ~SED!. In SED the statistical character of quantum measurements is imitated by the introduction of a stochastic classical background electromagnetic field. Random electromagnetic fluctu...
متن کاملElectromagnetic Interaction of Anyons in Non-relativistic Quantum Field Theory
The non-relativistic quantum field theoretic lagrangian which describes an anyon system in the presence of an electromagnetic field is identified. A non-minimal magnetic coupling to the Chern-Simons statistical field as well as to the electromagnetic field together with a direct coupling between both fields are the non trivial ingredients of the lagrangian obtained from the non relativistic lim...
متن کاملElectromagnetic Form Factors of Hadrons in Quantum Field Theories
In this talk, recent results are presented of calculations of electromagnetic form factors of hadrons in the framework of two quantum field theories (QFT), (a) Dual-Large Nc QCD (DualQCD∞) for the pion, proton, and ∆(1236), and (b) the Kroll-Lee-Zumino (KLZ) fully renormalizable Abelian QFT for the pion form factor. Both theories provide a QFT platform to improve on naive (tree-level) Vector Me...
