Magic angle conditions for twisted 3D topological insulators
Aaron Dunbrack, Jennifer Cano
We derive a general low-energy theory for twisted moiré heterostructures comprised of Dirac materials. We apply our theory to heterostructures on the surface of a three dimensional…
Dynamical Mean Field Theory of Moiré Bilayer Transition Metal Dichalcogenides: Phase Diagram, Resistivity, and Quantum Criticality
Jiawei Zang, Jie Wang, Jennifer Cano +2
We present a comprehensive dynamical mean field study of the triangular lattice moiré Hubbard model, which is believed to represent the physics of moiré bilayer transition metal di…
Staggered Pseudo Magnetic Field in Twisted Transition Metal Dichalcogenides: Physical Origin and Experimental Consequences
Jie Wang, Jiawei Zang, Jennifer Cano +1
Strong magnetic fields profoundly affect the quantum physics of charged particles, as seen for example by the integer and fractionally quantized Hall effects, and the fractal `Hofs…
Topological semimetals without quasiparticles
Haoyu Hu, Lei Chen, Chandan Setty +8
The interplay between interactions and topology in quantum materials is of extensive current interest. Strong correlations are known to be important for insulating topological stat…
Classification of Dirac points with higher-order Fermi arcs
Yuan Fang, Jennifer Cano
Dirac semimetals lack a simple bulk-boundary correspondence. Recently, Dirac materials with four-fold rotation symmetry have been shown to exhibit a higher order bulk-hinge corresp…
Topological Semimetal driven by Strong Correlations and Crystalline Symmetry
Lei Chen, Chandan Setty, Haoyu Hu +9
Electron correlations amplify quantum fluctuations and, as such, they have been recognized as the origin of a rich landscape of quantum phases. Whether and how they lead to gapless…
