Counterrotational effects on stability of 2+1-dimensional thin-shell wormholes
arXiv:1407.4673 · doi:10.1140/epjc/s10052-014-3073-2
Abstract
The role of angular momentum in a 2+1-dimensional rotating thin-shell wormhole (TSW) is considered. Particular emphasis is made on stability when the shells (rings) are counterrotating. We find that counter-rotating halves make the TSW supported by the equation of state of a linear gas more stable. Under a small velocity dependent perturbation, however, it becomes unstable.
