Topological Flat bands in graphene super-moiré lattices

MM Al Ezzi, J Hu, A Ariando, F Guinea, S Adam - Physical Review Letters, 2024 - APS
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 - Physical Review B, 2025 - APS
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

MMA Ezzi, L Peng, Z Liu, JHZ Chao… - arxiv preprint arxiv …, 2024 - arxiv.org
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 …

Competition of exchange and correlation energies in two-dimensional -component electron gas ferromagnetism

CH Huang, C Huang, MA Cazalilla - Physical Review B, 2025 - APS
Motivated by recent observations of symmetry-broken phases in lightly doped multilayer
graphene, we investigate magnetic phase transitions in a generalized electron gas model …

Many-body perturbation theory for moir\'{e} systems

L Peng, G Vignale, S Adam - arxiv preprint arxiv:2502.06968, 2025 - arxiv.org
Moir\'{e} systems such as magic-angle twisted bilayer graphene have attracted significant
attention due to their ability to host correlated phenomena including superconductivity and …
