Query: Shot noise in charge and magnetization currents of a quantum ring   The shot noise in a quantum ring, connected to leads, is studied in the
presence of electron interactions in the sequential tunneling regime. Two
qualitatively different noise correlations with distinctly different behaviors
are identified and studied in a large range of parameters. Noise in the total
current is due to the discreteness of the electron charge and can become
super-Poissonian as result of electron interaction. The noise in the
magnetization current is comparatively insensitive to the interaction but can
be greatly enhanced if population inversion of the angular states is assumed.
The characteristic time scales are studied by a Monte-Carlo simulation.
