摘要：

We obtained exact specific heat of the quantum compass model on the square L x L clusters with L = 2; 3; 4; 5 using Kernel Polynomial Method and compare them with the specific heat of a large compass ladder. Intersite correlations found in the ground state for these systems demonstrate that the quantum compass model differs from its classical version.
