Effective classical correspondence of the Mott transition

Danqing Hu, Jian-Jun Dong, Li Huang, Lei Wang, Yi-feng Yang

摘要:

在动力学平均场论的框架下,利用连续时间量子Monte Carlo的杂化展开,导出了描述半满单带哈伯德模型Mott跃迁的有效经典模型.我们发现了一个简单的两体相互作用的指数形式,并揭示了一个经典的对应的莫特过渡驱动的相互作用长度的几何发散。我们的工作为理解Mott物理提供了一个新的视角,并为扩展量子到经典映射在理解凝聚态物理中的应用提供了新的可能性

英文摘要:

We derive an effective classical model to describe the Mott transition of the half-filled one-band Hubbard model in the framework of the dynamical mean-field theory with hybridization expansion of the continuous time quantum Monte Carlo. We find a simple two-body interaction of exponential form and reveal a classical correspondence of the Mott transition driven by a logarithmically divergent interaction length. Our work provides an alternative angle to view the Mott physics and suggests a renewed possibility to extend the application of the quantum-to-classical mapping in understanding condensed matter physics
