Theory of Magic Angles in Twisted Bilayer Graphene: from Non-Abelian Gauge Fields to Flat Bands
Leonardo A. Navarro-Labastida, Gerardo G. Naumis
At a discrete set of ``magic'' twist angles, twisted bilayer graphene develops two bands at charge neutrality that are almost perfectly flat. We present a unified theory of this ph…
The First Magic Angle Beyond the Chiral Limit in Twisted Bilayer Graphene
Leonardo A. Navarro-Labastida, Pierre A. Pantaleon, Francisco Guinea +1
We develop a squared-Hamiltonian description of twisted bilayer graphene beyond the chiral limit to explain why the first magic angle remains robust under lattice relaxation, while…
Gap-controlled thermalization in a SSH model version of the Fermi-Pasta-Ulam-Tsingou chain
José A. Aké, Gerardo G. Naumis
In classical anharmonic lattices, the resonance structure driving nonlinear mode mixing is reshaped by band gaps. However, it remains unclear whether a spectral gap hinders or prom…
Magnetic phase transitions protected by topological quantum geometry transitions: effects of electron-electron interactions in the Creutz ladder system
Abdiel de Jesús Espinosa-Champo, Gerardo G. Naumis
The interplay between electronic correlations and band topology is a central theme in modern condensed matter physics. In this work, we investigate the effects of on-site Hubbard i…
Electronic structure and optical signatures of highly-doped graphene
Saúl Antonio Herrera-González, Guillermo Parra-Martínez, Francisco Guinea +3
Heavily doping graphene by intercalation can raise its Fermi level near an extended van Hove singularity, potentially inducing correlated electronic phases. Intercalation also modi…
Hyperbolic Plasmon dispersion and Optical Conductivity of Holey Graphene: signatures of flat-bands
Abdiel de Jesús Espinosa-Champo, Gerardo G. Naumis
Holey graphene (HG) is a novel two-dimensional (2D) material that has attracted considerable attention due to its remarkable electrical, thermal, and mechanical properties. The rec…
