Spectroscopy of Twisted Bilayer Graphene Correlated Insulators
Dumitru Călugăru, Nicolas Regnault, Myungchul Oh +6
We analytically compute the scanning tunneling microscopy (STM) signatures of integer-filled correlated ground states of the magic angle twisted bilayer graphene (TBG) narrow bands…
General Construction and Topological Classification of All Magnetic and Non-Magnetic Flat Bands
Dumitru Călugăru, Aaron Chew, Luis Elcoro +3
Exotic phases of matter emerge from the interplay between strong electron interactions and non-trivial topology. Owing to their lack of dispersion at the single-particle level, sys…
TSTG I: Single-Particle and Many-Body Hamiltonians and Hidden Non-local Symmetries of Trilayer Moiré Systems with and without Displacement Field
Dumitru Călugăru, Fang Xie, Zhi-Da Song +3
We derive the Hamiltonian for trilayer moiré systems with the Coulomb interaction projected onto the bands near the charge neutrality point. Motivated by the latest experimental re…
