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…
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…
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…
High-temperature superconductivity in flat-band sheared bilayer graphene
Jose Gonzalez, Tobias Stauber
We propose a new route to induce flat bands with a strong superconducting instability in graphene bilayers with heteroshear, where the 1D character of the moiré leads to stronger c…
Nonflat bands and chiral symmetry in magic-angle twisted bilayer graphene
Miguel Sánchez Sánchez, José González, Tobias Stauber
In this work, we study an interacting tight-binding model of magic-angle twisted bilayer graphene (MATBG), with a twist angle of . We derive effective theories based on…
Optical response of alternating twisted trilayer graphene
Dionisios Margetis, Guillermo Gómez-Santos, Tobias Stauber
We study the optical response of the alternating twisted trilayer graphene by making use of a unitary transformation for the trilayer Hamiltonian and the Kubo formulation of linear…
