Fermi velocity, interlayer couplings, and magic angle renormalization in twisted bilayer graphene
Miguel Sánchez Sánchez, José González, Tobias Stauber
Through extensive self-consistent Hartree-Fock calculations in a tight-binding model of twisted bilayer graphene (TBG), we show that many-body effects lead to a considerable increa…
In-plane magnetic response and Maki parameter of alternating-twist multilayers
Igor Vasilevskiy, Miguel Sánchez Sánchez, Miguel Sánchez Sánchez +5
We analytically study the orbital response of alternating-twist multilayer graphene to an in-plane magnetic field using the unitary transformation introduced by Khalaf et al. [Phys…
Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
Flat-band projected versus fully atomistic twisted bilayer graphene
Miguel Sánchez Sánchez, Tobias Stauber
We benchmark the recently proposed projection method [Phys. Rev. B 111, 205133 (2025)] for magic-angle twisted bilayer graphene (MATBG) across various symmetry-breaking phases at c…
