Contribution of remote bands to orbital magnetization in twisted bilayer graphene
Pinzhuo Li, Kun Jiang, Ziqiang Wang +2
Motivated by recent theoretical and experimental works on orbital magnetization for the interacting system, we develop a gauge-invariant framework to compute $M_…
The Mottness and the Anderson localization in bilayer nickelate LaNiO
Yuxin Wang, Ziyan Chen, Yi Zhang +2
The oxygen content plays a pivotal role in determining the electronic and superconducting properties of the recently discovered LaNiO superconductors. In this work…
Anderson localization: a density matrix approach
Ziyue Qi, Yi Zhang, Mingpu Qin +2
Anderson localization is a quantum phenomenon in which disorder localizes electronic wavefunctions. In this work, we propose a new approach to study Anderson localization based on…
Spin-triplet pair density wave superconductors
Yi Zhang, Ziqiang Wang
Recent experiments have shown that the nonzero center of mass momentum pair density wave (PDW) is a widespread phenomenon observed over different superconducting materials. However…
Josephson diodes induced by the loop current states
Qi-Kai Shen, Yi Zhang
We study the diode effect of the supercurrent in the Josephson junctions with the loop current states as the tunneling barrier. The loop current states are realized by the Haldane…
