Comment on "Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation"
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/29
It has been recently argued [arXiv:1205.0096] that the Lorentz force is incompatible with Special Relativity and should be amended in the presence of magnetization and polarization in order to avoid a...
Trouble with the Lorentz law of force: Incompatibility with special relativity and momentum conservation
the Lorentz law of force Incompatibility special relativity momentum conservation Optics
2012/5/17
The Lorentz law of force is the fifth pillar of classical electrodynamics, the other four being Maxwell's macroscopic equations. The Lorentz law is the universal expression of the force exerted by ele...

Magnetic moment non-conservation in magnetohydrodynamic turbulence models
Magnetic moment non-conservation magnetohydrodynamic turbulence models Plasma Physics
2012/4/19
The fundamental assumptions of the adiabatic theory do not apply in presence of sharp field gradients as well as in presence of well developed magnetohydrodynamic turbulence. For this reason in such c...
A Space-time Smooth Artificial Viscosity Method For Nonlinear Conservation Laws
Space-time Smooth Artificial Viscosity Method Nonlinear Conservation Laws Computational Physics
2012/4/19
We introduce the $C$-method, a simple scheme for adding localized, space-time smooth, artificial viscosity to nonlinear systems of conservation laws which propagate shock waves, rarefactions, and cont...
Nonlinear self-adjointness and conservation laws
Conservation laws Nonlinear self-adjointness Diffusion Kompaneets equation KP equation
2011/9/20
Abstract: The general concept of nonlinear self-adjointness of differential equations is introduced. It includes the linear self-adjointness as a particular case. Moreover, it embraces the strict self...
Effects of Momentum Conservation and Flow on Angular Correlations at RHIC
Effects of Momentum Conservation Flow on Angular Correlations RHIC
2011/1/7
Correlations of azimuthal angles observed at RHIC have gained great attention due to the prospect of identifying uctuations of parity-odd regions in the eld sector of QCD.
Conservation laws, integrability and transport in one-dimensional quantum systems
Conservation laws one-dimensional quantum systems
2010/11/18
In integrable one-dimensional quantum systems an infinite set of local conserved quantities exists which can prevent a current from decaying completely. For cases like the spin current in the XXZ mode...
On the spectral vanishing viscosity method for periodic fractional conservation laws
spectral vanishing viscosity method periodic fractional conservation laws
2010/11/22
We introduce and analyze a spectral vanishing viscosity approximation of periodic fractional conservation laws. The fractional part of these equations can be a fractional Laplacian or other non-local ...
We show that the total quantum efficiency of multiple optical modes cannot increase under linear-optical processing. That is, the sum of quantum efficiencies of any K output modes of a linear-optical ...
Conservation laws and normal forms of evolution equations
Conservation laws normal forms evolution equations
2010/4/6
We study local conservation laws for evolution equations in two independent variables. In particular, we present normal forms for the equations admitting one or two low-order conservation laws. Exampl...

2010/4/2
The Abelian Sandpile generates complex and beautiful patterns and seems to display allometry. On the plane, beyond patches, patterns periodic in both dimensions, we remark the presence of structures p...

2010/3/18
It has been shown recently that information is lost in the Hawking radiation of the linear dilaton black holes in various theories when applying the tunneling formulism without considering quantum gra...
Noether Symmetries and Covariant Conservation Laws in Classical, Relativistic and Quantum Physics
Noether Symmetries Quantum Physics Covariant Conservation Laws
2010/3/18
We review the Lagrangian formulation of Noether symmetries (as well as "generalized Noether symmetries") in the framework of Calculus of Variations in Jet Bundles, with a special attention to so-calle...

2010/4/7
We consider the construction of the deformed Whitham system for the KdV-equation in the one-phase case and investigate the conservation of the Hamiltonian properties in this situation. It is shown the...
