竞争秩序的“内在不确定性”在最近的强关联系统研究中引起了浓厚的兴趣。高温超导体中的超导能隙在纳米尺度上是不均匀的，其自相关函数与星系分布非常相似。我们研究了强关联体系中的输运性质，发现了电荷有序有机导体中的一种新的非均匀态。这种特殊的材料可能是自引力系统的一个很好的运动场，因为（i）库仑相互作用是未屏蔽的，因此在电荷有序状态下是长程的。(ii)该系统接近量子临界点，在那里所有的物理性质都是标度不变的。(iii)电荷有序畴伴随着晶格应变，晶格应变作为长程吸引力起作用。
``Intrinsic inhomogeneity'' by competing orders has attracted a keen interest in recent studies of strongly correlated systems. The superconducting gap is inhomogeneous at a nanoscale in high-temperature superconductors, the auto correlation function of which quite resembles that of the galaxy distribution. We have studied transport properties in strongly correlated systems, and have found a novel inhomogeneous state in a charge-ordered organic conductor. This particular material could be a good playground for self-gravitating systems, because (i) the Coulomb interaction is unscreened and thus long-ranged in the charge-ordered state. (ii) The system is close to the quantum critical point, where all the physical properties are scale invariant. (iii) The charge ordered domain accompanies lattice strain which works as a long-range attractive force.
