摘要：

We predict a glass transition in the recently discovered flux-fluid state of high-Tc superconductors due to topological entanglements. Two possible relaxation mechanisms are consideredsingle-flux-line motion with relaxation time exp{exp[(/d)2]}, and collective motion of many flux lines with relaxation time colexp[(/d)6], where is the magnitude of transverse fluctuations of flux lines and d is the intervortex spacing. This extremely slow relaxation enables the system of entangled flux lines to support supercurrents in the presence of only a few strong pinning centers. © 1990 The American Physical Society.
