Abstract
We obtained exact heat capacities 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 heat capacity 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.
