Electromagnetic properties of nucleons and hyperons in a Lorentz covariant quark model
Magnetic nuclear lorentz covariance the bound state quark let-down pseudo-scalar meson
2014/12/20
We calculate magnetic moments of nucleons and hyperons and N -> Delta + gamma transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound st...

We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
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...
Does Lorentz Force Law Contradict the Principle and Theories of Relativity for Uniform Linear Motion?
Lorentz Force Law Principle and Theories of Relativity Uniform Linear Motion Classical Physics
2012/5/29
I show that no force or torque is generated in cases involving a charge and a magnet with their relative velocity zero, in any inertial frame of reference. A recent suspicion of an anomalous torque an...
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...
视频：南京大学大学物理学第23讲 Lorentz force。
Analytical results for the anisotropic collective flow of a Lorentz gas of massless particles scattering on fixed centres are presented.
Plane waves in a moving medium and the Lorentz covariance of Minkowski's photon and electromagnetic momentum-energy four-vectors
invariance of phase, wave four-vector, moving dielectric medium, light momentum in medium
2011/8/30
In this paper, invariant forms of refractive index, phase velocity, and group velocity are defined for plane waves in a moving medium. From the covariant wave four-vector combined with Einstein’s ligh...
A new limit on Lorentz-violating tensor interactions set using $^{21}$Ne-Rb-K comagnetometer
Lorentz-violating 21Ne-Rb-K comagnetometer
2011/8/29
We develop a comagnetometer using 21Ne atoms with nuclear spin I = 3=2 and Rb atoms polarized by spin-exchange with K atoms to search for tensor interactions that violate local Lorentz invariance.We f...

Lorentz-breaking fermionic condensates N strongly-coupled Lattice Gauge Theories
2010/12/24
The possibility of Lorentz symmetry breaking (LSB) has attracted considerable attention in recent years for a variety of reasons, including the attractive prospect of the graviton as a Goldstone boson...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Unified cosmic history modified gravity
2010/12/24
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structure and cosm...

Quantum-Gravity Induced Lorentz Violation and Dynamical Mass Generation
Quantum-Gravity Induced Lorentz Violation Dynamical Mass Generation
2010/12/27
In Ref. [1] (by J. Alexandre) a minimal extension of (3+1)-dimensional Quantum Electrodynamics has been proposed, which includes Lorentz-Violation (LV) in the form of higher-(spatial)-derivative isotr...
Lorentz invariance, nonzero minimal uncertainty in position, and inhomogeneity of space at the Planck scale
Lorentz invariance nonzero minimal uncertainty
2010/12/24
The suspicion that the existence of a minimal uncertainty in position measurements violates Lorentz invariance seems unfounded. It is shown that the existence of such a nonzero minimal uncertainty in...
