Continuous correlated states and dual-flatness in a moiré heterostructure
Mohammed M. Al Ezzi, Na Xin, Yanmeng Shi +13
Many-body effects in condensed matter yield novel quantum states when the electronic density of states is enhanced. A vivid example is flat bands, which suppress kinetic energy and…
Wavefunction textures in twisted bilayer graphene from first principles
Albert Zhu, Daniel Bennett, Daniel T. Larson +3
Motivated by recent experiments probing the wavefunctions of magic-angle twisted bilayer graphene (tBLG), we perform large-scale first-principles calculations of tBLG with full ato…
Universal Symmetries in Twisted Moiré Materials
Mohammed M. Al Ezzi, Albert Zhu, Daniel Bennett +2
Two-dimensional multi-layer materials with an induced moiré pattern, either due to strain or relative twist between layers, provide a versatile platform for exploring strongly corr…
Tunable van Hove Singularities and Correlated States in Twisted Trilayer Graphene
Yanmeng Shi, Shuigang Xu, Mohammed M. Al Ezzi +16
Understanding and tuning correlated states is of great interest and significance to modern condensed matter physics. The recent discovery of unconventional superconductivity and Mo…
