论文摘要
我们发现,在周围环境中存在弱不一致的效果的情况下,最近的邻居紧密结合链的零温度电导率显示出违反直觉的幂律生长,具有系统的长度,表明超级尺度的缩放。这种引人入胜的环境有助于超级尺度的电导缩放,这是在系统长度的有限但扩展的制度上发生的。可以通过减少与周围环境的耦合来系统地扩展这种缩放制度。对于孤立系统没有相应的类似物。这种超大型缩放源于周围环境的不一致效果的复杂相互作用,以及在每个带边缘上发生的系统传输矩阵的特殊点。
We find that, in the presence of weak incoherent effects from surrounding environments, the zero temperature conductance of nearest neighbour tight-binding chains exhibits a counter-intuitive power-law growth with system length at band-edges, indicating superballistic scaling. This fascinating environment assisted superballistic scaling of conductance occurs over a finite but extended regime of system lengths. This scaling regime can be systematically expanded by decreasing the coupling to the surrounding environments. There is no corresponding analog of this behavior for isolated systems. This superballistic scaling stems from an intricate interplay of incoherent effects from surrounding environments and exceptional points of the system's transfer matrix that occur at every band-edge.
