标题： Finite-size corrections of an integrable chain with alternating spins

摘要： 本文计算了一条各向异性可积自旋链的有限尺寸修正，该自旋链由自旋 s = 1 和 s = 1/2 的自旋组成。 这些计算是在相图的两个区域中针对两个耦合$\bar{c}$和$\tilde{c}$进行的。 在共形不变的情况下，我们得到了基态及其最低激发的能量，这推广了早期的结果。 显示英文摘要

摘要： In this paper we calculate the finite-size corrections of an anisotropic integrable spin chain, consisting of spins s=1 and s=1/2. The calculations are done in two regions of the phase diagram with respect to the two couplings $\bar{c}$ and $\tilde{c}$. In case of conformal invariance we obtain the final answer for the ground state and its lowest excitations, which generalizes earlier results.
