连续量子临界Mott跃迁的尺度解耦

Dimensional decoupling at continuous quantum critical Mott transitions

Liujun Zou, T. Senthil

摘要:

对于二维层状系统中的连续Mott金属-绝缘体相变,我们证明了空间解耦现象:系统在费米液体侧表现为三维金属,而在莫特绝缘体侧表现为解耦的二维层的堆叠.我们证明了维数解耦发生在Mott量子临界点本身。我们推导出在这样一个连续的莫特转变附近的各种交叉制度的层间电导率的温度依赖性,并讨论了实验的影响。

英文摘要:

For continuous Mott metal-insulator transitions in layered two dimensional systems, we demonstrate the phenomenon of dimensional decoupling: the system behaves as a three-dimensional metal in the Fermi liquid side but as a stack of decoupled two-dimensional layers in the Mott insulator. We show that the dimensional decoupling happens at the Mott quantum critical point itself. We derive the temperature dependence of the interlayer electric conductivity in various crossover regimes near such a continuous Mott transition, and discuss experimental implications.
