具有猝灭中心无序的量子自旋系统的相关不等式

Correlation Inequalities for Quantum Spin Systems with Quenched Centered Disorder

Pierluigi Contucci, Joel L. Lebowitz

摘要:

结果表明,在经典情形下,具有中心无序的随机量子自旋系统满足已证明的相关不等式(arXiv:cond-mat/0612371).结果包括压力和基态能量单调接近热力学极限。对于有限程势,还导出了不同边界条件下表面压力的符号和界。

英文摘要:

It is shown that random quantum spin systems with centered disorder satisfy correlation inequalities previously proved (arXiv:cond-mat/0612371) in the classical case. Consequences include monotone approach of pressure and ground state energy to the thermodynamic limit. Signs and bounds on the surface pressures for different boundary conditions are also derived for finite range potentials.
