Abstract:
We study acceleration of current-carrying string loops governed by
presence of an outer tension barrier and an inner angular momentum
barrier in the field of black holes. Relativistic current carrying
strings moving axisymmetrically along the axis of a black hole could in
a simplified way represent plasma that exhibits associated string-like
behavior. We demonstrate that string loops can be scattered near the
black hole horizon and the energy of string oscillations can be
efficiently converted to the energy of their linear motion. Such a
transmutation effect can potentially represent acceleration of jets in
active galactic nuclei and microquasars.
