我们回顾了布洛赫关于量子系统中不存在宏观稳态电流的定理的证明。标准证明表明,在相当一般的条件下,在大体积极限中,1D中的电流为零。在更高的维度中,横截面上的总电流在无隙系统中不需要为零,但在有隙系统中却为零。我们专注于后一种说法,并给出了一个独立的证明动机最近引入的多体电荷输运的量子晶格系统具有守恒电荷的指数。
We review the proofs of a theorem of Bloch on the absence of macroscopic stationary currents in quantum systems. The standard proof shows that the current in 1D vanishes in the large volume limit under rather general conditions. In higher dimensions, the total current across a cross-section does not need to vanish in gapless systems but it does vanish in gapped systems. We focus on the latter claim and give a self-contained proof motivated by a recently introduced index for the many-body charge transport in quantum lattice systems having a conserved-charge.
