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...

2014/12/9
This thesis presents a series of results relating to conserved charges in general relativity. In particular, we give a general expression for a gravitational charge corresponding to a boost Killing ve...
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 ...

2010/12/7
This is the first part of our mathematical survey on the equations of motion of classical absorber electrodynamics, which shall be introduced and discussed briefly. Its basic equations of motion are t...

2010/12/15
We perform a nonrelativistic contraction of N-extended Poincar´e superalgebra with internal symmetry U(N) and general set of N(N −1) real central charges.
Axial charges of N(1535) and N(1650) in two-flavor lattice QCD

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 ...
Conserved Gravitational Charges, Locality and the Holographic Weyl Anomaly - a Fresh Viewpoint
Gravitational Charges the Holographic Weyl Anomaly asymptotic isometries
2010/10/18
Since the proposal of the AdS/CFT correspondence, made by Maldacena and Witten, there has been some controversy about the definition of conserved Noether charges associated with asymptotic isometries ...
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 ...
