Lifshitz Transition in Triangular Lattice Kondo-Heisenberg Model
Lan Zhang, Hong-Gang Luo, Yin Zhong
Motivated by recent experimental progress on triangular lattice heavy-fermion compounds, we investigate possible Lifshitz transitions and the scanning tunnel microscope (STM) spect…

Hidden Anderson Localization in Disorder-Free Ising-Kondo Lattice
Wei-Wei Yang, Lan Zhang, Xue-Ming Guo +1
Anderson localization (AL) phenomena usually exists in systems with random potential. However, disorder-free quantum many-body systems with local conservation can also exhibit AL o…

Resistivity minimum emerges in Anderson impurity model modified with Sachdev-Ye-Kitaev interaction
Lan Zhang, Yin Zhong, Hong-Gang Luo
We investigate a modified Anderson model at the large- limit, where Coulomb interaction is replaced by Sachdev-Ye-Kitaev random interaction. The resistivity of conduction electr…
