摘要：

The one-dimensional spin-1/2 quantum compass model is considered. There is a multicritical point in the ground state magnetic phase diagram of the model. By using the Jordan-Wigner transformation the diagonalized Hamiltonian is obtained and analytic expressions for the spin spin correlation functions are determined at the multicritical point. On the other hand, the critical exponent of the energy gap in the vicinity of the multicritical point is calculated by a practical finite size scaling approach. DOI:10.5506/APhysPolB.44.221
