【 摘 要 】

We present an analytic enumeration of the metastable states N-s in a periodic long-range Josephson array frustrated by a transverse field. We find that the configurational entropy, S(conf)equivalent to ln N-s, is extensive and scales with frustration, confirming that the nonrandom system is glassy. We also find that S-conf is different from that of its disordered analogue, despite the fact that the two models share the same dynamical equations.
