Lipkin-Meshkov-Glick模型中的几何相位和量子相变

Geometric Phase and Quantum Phase Transition in the Lipkin-Meshkov-Glick model

H. T. Cui, K. Li, X. X. Yi

摘要:

在Lipkin-Meshkov-Glick模型中讨论了几何相位与量子相变之间的关系。我们的计算显示了基态几何相位对该模型中量子相变的标记能力。讨论了几何相位及其导数作为表征量子相变的普适序参量的可能性。

英文摘要:

The relation between the geometric phase and quantum phase transition has been discussed in the Lipkin-Meshkov-Glick model. Our calculation shows the ability of geometric phase of the ground state to mark quantum phase transition in this model. The possibility of the geometric phase or its derivatives as the universal order parameter of characterizing quantum phase transitions has been also discussed.
