Quantum XY spin glass model with planar Dzyaloshinskii-Moriya interactionsin longitudinal field

In the replica symmetric approximation and static limit in Matsubara "imagi nary time", the quantum XY spin glass model with planar Dzyaloshinskii-Mori ya interaction in longitudinal field is investigated. Several thermodynamic quantities are calculated numerically as well as spin self-interaction and spin glass order parameter for spin S = 1/2. It is shown that the entropy is not independent of the field. A crossover behavior of the specific heat depending on temperature is found. There is a deviation from the parabolic approximation, C/T = A + Bh(2).
