论文摘要
我们在排斥，完全沮丧的单频哈伯德模型中展示了一阶金属 - 绝缘子相变，这是耦合到费米昂浴的函数。浴耦合的时间依赖性操作允许在整个相变和共存区域之间在金属和绝缘状态之间切换。我们提出了一个简单的纳米电机设备，用于实验实现对浴耦合的动态控制。对设备特征的分析表明，它可以充当两末端的备忘录。
We demonstrate a first order metal-insulator phase transition in the repulsive, fully frustrated, single-band Hubbard model as a function of the coupling to a fermion bath. Time dependent manipulation of the bath coupling allows switching between metallic and insulating states both across the phase transition and within the coexistence region. We propose a simple nanoelectronic device for experimentally realizing dynamic control of the bath coupling. Analysis of the device characteristics shows that it can act as a two-terminal memristor.
