Topological Flat bands in graphene super-moiré lattices
Moiré-pattern-based potential engineering has become an important way to explore exotic
physics in a variety of two-dimensional condensed matter systems. While these potentials …

Dirac-point spectroscopy of flat-band systems with the quantum twisting microscope
N Wei, F von Oppen, LI Glazman - arxiv preprint arxiv:2410.08383, 2024 - arxiv.org
Motivated by the recent development of the quantum twisting microscope, we formulate a
theory of elastic momentum-resolved tunneling across a planar tunnel junction between a …

A self-consistent Hartree theory for lattice-relaxed magic-angle twisted bilayer graphene
For twisted bilayer graphene close to magic angle, we show that the effects of lattice
relaxation and the Hartree interaction both become simultaneously important. Including both …
