Mean-field Modelling of Moiré Materials: A User's Guide with Selected Applications to Twisted Bilayer Graphene
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We review the theoretical modelling of moiré materials, focusing on various aspects of magic-angle twisted bilayer graphene (MA-TBG) viewed through the lens of Hartree-Fock mean-fi…
Putting a new spin on the incommensurate Kekulé spiral: from spin-valley locking and collective modes to fermiology and implications for superconductivity
Ziwei Wang, Glenn Wagner, Yves H. Kwan +3
We revisit the global phase diagram of magic-angle twisted bilayer and [symmetric] trilayer graphene (MA-TBG/TSTG) in light of recent scanning tunneling microscopy (STM) measuremen…
When Could Abelian Fractional Topological Insulators Exist in Twisted MoTe (and Other Systems)
Yves H. Kwan, Glenn Wagner, Jiabin Yu +6
Using comprehensive exact diagonalization calculations on twisted bilayer MoTe (MoTe), as well as idealized Landau level models also relevant for…
Textured Exciton Insulators
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We introduce and study new interacting topological states that arise in time-reversal symmetric bands with an underlying obstruction to forming localized states. If the vall…
Chern-Textured Exciton Insulators with Valley Spiral Order in Moiré Materials
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We explore the phase diagrams of moiré materials in search of a new class of intervalley-coherent correlated insulating state: the Chern texture insulator (CTI). This phase of matt…
