论文摘要
使用Phys中开发的自洽理论，在简单的立方晶格上在低温下在低温下研究了半充满的亲藤晶格模型。 Rev. B 96，075115（2017）。发现在温度跳跃平面中具有三个不同的绝缘阶段，即强耦合昆多单重（KS）相，倒置的昆多单重（IKS）相通过反转与KS区分开，而抗fiferromagagnetic（AFM）相。跨反转过渡的状态的准粒子密度被发现显示出尺寸还原，在实验中可以区分KS和IKS绝缘子。发现在IK和AFM相中获得的磁量子振荡显示出具有温度和反向跳跃的Lifshitz-Kosevich类似行为。
The half-filled Kondo lattice model is studied at low temperatures on simple cubic lattice using the self-consistent theory developed in Phys. Rev. B 96, 075115 (2017). It is found to have three distinct insulating phases in the temperature-hopping plane, namely, the strong coupling Kondo singlet (KS) phase, the inverted Kondo singlet (iKS) phase distinguished from the KS by inversion, and the antiferromagnetic (AFM) phase. The quasiparticle density of states across the inversion transition is noted to exhibit dimensional reduction, which can differentiate between the KS and iKS insulators in experiments. Magnetic quantum oscillations obtained in the iKS and AFM phases are found to show Lifshitz-Kosevich like behaviour with temperature as well as inverse hopping.
