Neutrinos, a window on new physics
J. W. van Holten
This paper reviews some aspects of the physics of neutrinos, in particular neutrino masses and the issue of Dirac versus Majorana neutrinos. The see-saw mechanism is described and…
Gauge-covariant extensions of Killing tensors and conservation laws
J. W. van Holten
In classical and quantum mechanical systems on manifolds with gauge-field fluxes, constants of motion are constructed from gauge-covariant extensions of Killing vectors and tensors…
Ballistic orbits in Schwarzschild space-time and gravitational waves from EMR binary mergers
G. d'Ambrosi, J. W. van Holten
We describe a special class of ballistic geodesics in Schwarzschild space-time, extending to the horizon in the infinite past and future of observer time, which are characterized b…
Conformal Killing Tensors and covariant Hamiltonian Dynamics
M. Cariglia, G. W. Gibbons, J. -W. van Holten +2
A covariant algorithm for deriving the conserved quantities for natural Hamiltonian systems is combined with the non-relativistic framework of Eisenhart, and of Duval, in which the…
Killing tensors and canonical geometry
M. Cariglia, G. W. Gibbons, J. -W. van Holten +3
The systematic derivation of constants of the motion, based on Killing tensors and the gauge covariant approach, is outlined. Quantum dots are shown to support second-, third- and…
