| Résumé : | The effective equations of motion of relativistic strings in material media are derived and applied to moving rings with a time-dependent radius. The equations contain the Magnus force, due to the motion of the ring relative to the medium, whose eventual effect is the possible stabilization of the ring against shrinking. A constant solution is identified, and small fluctuations around it are bound, demonstrating the stability of the solution. If the string loops created in the cosmological cosmic string scenario interact via this mechanism with a formed-up Higgs particle condensate, then the stabilizing velocities are ∼δloop/Rloop, and the overall effect of this phenomenon is to stabilize large loops and reduce the general disappearance rate of the string loops. © 1995 The American Physical Society. |
