论文摘要
我们考虑$ t = 0 $量子阶段的特性，尤其是超导和类似的自旋 - 液体阶段 - 在宽度$ l_ \ perp $的无限缸上，并分析了$ l_ \ perp \ to \ perp \ to \ for to \ for to \ forty $（2D）限制的方式。这个问题本身就是有趣的，但是在推断可访问的密度矩阵重新归一化组（DMRG）的情况下，模型对所需的2D限制强烈相互作用的问题的结果尤其重要。说明了从相对较小的$ l _ {\ perp} $结果得出关于2D量子阶段的各种方法的结论。
We consider the properties of $T=0$ quantum phases of matter - especially superconducting and analogous spin-liquid phases - on infinite cylinders of width $L_\perp$ and analyze the ways in which the $L_\perp \to \infty$ (2d) limit is approached. This problem is interesting in its own right, but is particularly important in the context of extrapolating accessible density matrix renormalization group (DMRG) results on model strongly interacting problems to the desired 2d limit. Various methods for drawing firm conclusions about the quantum phases in 2d from relatively small $L_{\perp}$ results are illustrated.
