Conserved gravitational charges from Yano tensors
Yano tensor time and space conservation of gravity
2014/12/20
The defining properties of Yano tensors naturally generalize those of Killing vectors to anti-symmetric tensor fields of arbitrary rank. We show how the Yano tensors of flat spacetime can be used to c...
We derive the Noether currents and charges associated with an internal galilean invariance---a symmetry recently postulated in the context of so-called galileon theories. Along the way we clarify the...

Relativistic Hydrodynamics General Anomalous Charges
2010/12/24
We consider the hydrodynamic regime of gauge theories with general triangle anomalies, where the participating currents may be global or gauged, abelian or non-abelian. We generalize the argument of ...
We derive the Noether currents and charges associated with an internal galilean invariance (x) ! (x)+b μ xμ—a symmetry recently postulated in the context of so-called galileon theories. Along the wa...
Axial charges of N(1535) and N(1650) in two-flavor lattice QCD
axial charge chiral symmetry negative parity nucleon
2009/11/24
We show the lattice QCD results on the axial charge gAN*N* of negative parity nucleon resonances, N*(1535) and N*(1650), which are key clues to the chiral structure in baryon sector. The measurements ...

We give a review of our recent work on conserved charges in cosmological spacetimes. We compute the mass and the angular momenta of various solutions in D dimensions. This is an extended version of a ...
Decoherence of Electron Waves Due to Induced Charges Moving Through a Nearby Resistive Material
Electron Waves Charges a Nearby Resistive Material
2010/10/13
An experiment in which decoherence, i.e. the transition from quantum to classical behaviour, can be studied in detail was proposed by Anglin and Zurek [1] and has now been realized. An electron beam i...
Surface Charges and External Electric Field in a Toroid Carrying a Steady Current
Surface Charges External Electric Field a Steady Current
2010/10/27
We solve the problem of a resistive toroid carrying a steady azimuthal current. We use standard toroidal coordinates, in which case Laplace’s equation is R-separable. We obtain the electric potential ...

2010/10/19
We study structural and spectral properties of finite classical systems of N two-dimensional charged particles, confined by a parabolic potential ∝ rn, and interacting via inverse power-law potentials...

Elementary charges classical electrodynamics
2010/4/15
In the framework of classical electrodynamics elementary particles are treated as capacitors. The electrostatic potentials satisfy equations of the Schrödinger type. An interesting "quantization ...
