Dirac quantum criticality in twisted double bilayer transition metal dichalcogenides
Jan Biedermann, Lukas Janssen
We investigate the phase diagram of moiré double bilayer transition metal dichalcogenides with ABBA stacking as a function of twist angle and applied pressure. At hole filling $ν…

Twist-tuned quantum criticality in moiré bilayer graphene
Jan Biedermann, Lukas Janssen
We argue that moiré bilayer graphene at charge neutrality hosts a continuous semimetal-to-insulator quantum phase transition that can be accessed experimentally by tuning the twis…
