A First Class Constraint Generates Not a Gauge Transformation,But a Bad Physical Change:The Case of Electromagnetism
empirical equivalence gauge freedom quantum gravity problem of time
2016/6/15
In Dirac-Bergmann constrained dynamics, a first-class constraint typically does not _alone_ generate a gauge transformation. By direct calculation it is found that each first-class constraint in Maxwe...
K ->pi pi phenomenology in the presence of electromagnetism
Electromagnetic the dollar the electromagnetic radiation
2014/12/22
We describe the influence of electromagnetism on the phenomenology of $K \to \pi\pi$ decays. This is required because the present data were analyzed without inclusion of electromagnetic radiative corr...
Abstract: Defining the generalized charge, potential, current and generalized fields as complex quantities where real and imaginary parts represent gravitation and electromagnetism respectively, corre...

2011/9/1
Recent work by T. G. Philbin [1] has provided a Lagrangian theory that establishes a general method for the canonical quantization of the electromagnetic field in dispersive, lossy, linear dielectrics...

2011/7/26
Abstract: We derive basic equations of electromagnetic fields in fractal media which are specified by three indepedent fractal dimensions {\alpha}_{i} in the respective directions x_{i} (i=1,2,3) of t...
Electromagnetism with Magnetic Charge and Two Photons
Electromagnetism Magnetic Charge classical electromagnetism High Energy Physics - Theory
2011/7/27
Abstract: The Dirac approach to include magnetic charge in Maxwell's equations places the magnetic charge at the end of a string on which the the fields of the theory develop a singularity. In this pa...

By using variational calculus and exterior derivative formalism, we proposed in [30] and [11] a new geometric approach to electromagnetism in pseudo-Finsler spaces.

2010/11/29
We prove existence of solution of a p-curl type evolutionary system arising in electromagnetism with a power nonlinearity of order p, 1 < p < 1,assuming natural tangential boundary conditions. We cons...

2010/10/21
Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption. This has led to a ...

Simple applications of Noether's first theorem in quantum mechanics and electromagnetism
Noether symmetry free Schrodinger equation
2008/4/22
Internal global symmetries exist for the free non-relativistic Schrodinger particle, whose associated Noether charges---the space integrals of the wavefunction and the wavefunction multiplied by the s...
Richard Feynman has claimed that anti-particles are nothing but particles `propagating backwards in time'; that time reversing a particle state always turns it into the corresponding anti-particle sta...

We study the evolution of cosmological magnetic fields in FRW models with curved spatial sections and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechan...
