Skyrmions in twisted bilayer graphene: stability, pairing, and crystallization
Yves H. Kwan, Glenn Wagner, Nick Bultinck +2
We study the excitations that emerge upon doping the translationally-invariant correlated insulating states in magic angle twisted bilayer graphene at various integer filling facto…
Global Phase Diagram of the Normal State of Twisted Bilayer Graphene
Glenn Wagner, Yves H. Kwan, Nick Bultinck +2
We investigate the full doping and strain-dependent phase diagram of the normal state of magic-angle twisted bilayer graphene (TBG). Using comprehensive Hartree-Fock calculations,…
-wave paired composite-fermion electron-hole trial state for quantum Hall bilayers with
Glenn Wagner, Dung X. Nguyen, Steven H. Simon +1
We introduce a new variational wavefunction for a quantum Hall bilayer at total filling , which is based on -wave BCS pairing between composite-fermion electrons in one la…
Kekulé spiral order at all nonzero integer fillings in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Tomohiro Soejima +4
We study magic angle graphene in the presence of both strain and particle-hole symmetry breaking due to non-local inter-layer tunneling. We perform a self-consistent Hartree-Fock s…
