Axial and electromagnetic observables of hyperons in 2-flavor chiral perturbation theory
Axial electromagnetic observables of hyperons 2-flavor chiral perturbation theory
2011/1/13
Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties.Such expansions should exhibit marked improvement over the conventional three-flavor chiral expansion.

Surfatron acceleration of a relativistic particle by electromagnetic plane wave
Surfatron acceleration relativistic particle electromagnetic plane wave
2010/11/16
We study motion of a relativistic charged particle in a plane slow electromagnetic wave and background uniform magnetic field. The wave propagates normally to the background field. Under certain condi...
Electromagnetic Corrections in Staggered Chiral Perturbation Theory
Electromagnetic Corrections Staggered Chiral Perturbation Theory
2011/1/14
To reduce errors in light-quark mass determinations, it is now necessary to consider electromagnetic contributions to light-meson masses. Calculations using staggered quarks and quenched photons are c...
A relativistic coupled-channel formalism for electromagnetic form factors of 2-body bound states
Relativistic quantum mechanics Few-body systems Electromagnetic structure
2011/1/6
We discuss a Poincar´e invariant coupled-channel formalism which is based on the point-form of relativistic quantum mechanics.
Electromagnetic modes of a disordered photonic crystal
Electromagnetic modes photonic crystal
2010/11/12
We present a systematic numerical approach to compute the eigenmodes and the related eigenfrequencies of a disordered photonic crystal, characterized by small fluctuations of the otherwise periodic di...
Interaction of the Electromagnetic S-Wave with the Thin Metal Film
Interaction the Electromagnetic S-Wave Thin Metal Film
2010/11/9
It is shown that for thin metal films, thickness of which does not exceed a thickness of a skin-layer, the problem allows analytical solution for any boundary conditions. The analysis of transmission...
Electromagnetic Klein-Gordon and Dirac equations in scale relativity
Electromagnetic Klein-Gordon Dirac equations scale relativity
2010/10/27
We present a new step in the foundation of quantum field theory with the tools of scale relativity. Previously, quantum motion equations (Schr¨odinger, Klein-Gordon, Dirac, Pauli) have been derived as...

Dynamical invariants Robertson-Schrodinger correlated states electromagnetic field nonstationary linear media
2010/10/21
Dynamical invariants and statistical properties of the quantized electromagnetic field in nonstationary linear media (dielectric and/or conductive) are considered in the framework of Choi-Yeon quantiz...
