Nov 4, 2022 · Here we study the phase diagram of TBG in the presence of heterostrain with unbiased, large-scale density matrix renormalization group calculations (bond dimension …

Dec 30, 2021 · This order, which we dub the “incommensurate Kekulé spiral” (IKS) order, spontaneously breaks both the emergent valley-charge conservation and moiré translation …

Aug 28, 2024 · Here we combine exciton sensing and optical pump–probe spectroscopy to investigate the dynamics of isospin orders in MATBG with WSe 2 substrate across the entire …

IKS (incommensurate Kekulé spiral) Intervalley coherence at a finite wavevector

Apr 12, 2022 · We demonstrate that the corresponding electronic compressibility and Fermi surface structure are consistent with the “cascade” physics and Landau fans observed …

Dec 14, 2021 · We find that with a small amount of strain, the phase diagram is dominated by a novel translation symmetry-breaking order dubbed the incommensurate Kekulé spiral (IKS), …

Nov 4, 2022 · Here we study the phase diagram of TBG in the presence of heterostrain with unbiased, large-scale density matrix renormalization group calculations (bond dimension …

We find that at all nonzero integer fillings very small strains, comparable to those measured in scanning tunneling experiments, stabilize a fundamentally new type of time-reversal …

We investigate the full doping and strain-dependent phase diagram of the normal state of magic-angle twisted bilayer graphene (TBG).

I will describe the properties and origin of the IKS, including its relation to the ‘strong coupling’ phases of TBG, and argue that our findings are broadly consistent with the set of experimental …
