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…
Beyond the Freshman's Dream: Classical fractal spin liquids from matrix cellular automata in three-dimensional lattice models
Sounak Biswas, Yves H. Kwan, S. A. Parameswaran
We construct models hosting classical fractal spin liquids on two realistic three-dimensional (3D) lattices of corner-sharing triangles: trillium and hyperhyperkagome (HHK). Both m…
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,…
One-Dimensional Luttinger Liquids in a Two-Dimensional Moiré Lattice
Pengjie Wang, Guo Yu, Yves H. Kwan +13
The Luttinger liquid (LL) model of one-dimensional (1D) electronic systems provides a powerful tool for understanding strongly correlated physics including phenomena such as spin-c…
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…
Quantum oscillations in the zeroth Landau Level and the serpentine Landau fan
T. Devakul, Yves H. Kwan, S. L. Sondhi +1
We identify an unusual mechanism for quantum oscillations in nodal semimetals, driven by a single pair of Landau levels periodically closing their gap at the Fermi energy as a magn…
