提出了在块体、无序、第二类超导体的混合态中存在一个新的热力学相的可能性：涡旋玻璃超导体。该相缺乏传统的非对角线长程有序，但被认为是一个真正的超导体，直流电阻为零。在这一阶段，亚稳态电流被预测为(LnT)−1/μ，μ(≤1)为普适指数。文中还提到了与块状高T_c氧化物实验的关系。
The possibility of a new thermodynamic phase in the mixed state of bulk, disordered, type-II superconductors is suggested: a vortex-glass superconductor. This phase lacks conventional off-diagonal long-ranged order, yet is argued to be a true superconductor with vanishing dc resistance. In this phase metastable currents are predicted to decay as (lnt)− 1/μ with μ (≤ 1) a universal exponent. Relevance to experiments on bulk high-T c oxides is mentioned.
