Spectroscopy Signatures of Electron Correlations in a Trilayer Graphene/hBN Moiré Superlattice
Jixiang Yang, Guorui Chen, Tianyi Han +12
ABC-stacked trilayer graphene/hBN moiré superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hB…
Small to large Fermi surface transition in a single band model, using randomly coupled ancillas
Alexander Nikolaenko, Maria Tikhanovskaya, Subir Sachdev +1
We describe a solvable model of a quantum transition in a single band model involving a change in the size of the electron Fermi surface without any symmetry breaking. In a model w…
Competing correlated states and abundant orbital magnetism in twisted monolayer-bilayer graphene
Minhao He, Ya-Hui Zhang, Yuhao Li +5
Flat band moiré superlattices have recently emerged as unique platforms for investigating the interplay between strong electronic correlations, nontrivial band topology, and multip…
Doping the chiral spin liquid -- topological superconductor or chiral metal?
Xue-Yang Song, Ashvin Vishwanath, Ya-Hui Zhang
We point out that there are two different chiral spin liquid states on the triangular lattice and discuss the conducting states that are expected on doping them. These states label…
Direct observation of distinct minibands in moiré superlattices
Saien Xie, Brendan D. Faeth, Yanhao Tang +10
Moiré superlattices comprised of stacked two-dimensional materials present a versatile platform for engineering and investigating new emergent quantum states of matter. At present,…
Fractional Fermi liquid in a generalized model
Ya-Hui Zhang, Zheng Zhu
Inspired by the recent discovery of superconductivity in the nickelate NdSrNiO, we study a generalized model to investigate the correlated phases induced by d…
