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…
Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-DomÃnguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
Nematic versus Kekulé phases in twisted bilayer graphene under hydrostatic pressure
Miguel Sánchez Sánchez, Israel DÃaz, José González +1
We address the precise determination of the phase diagram of magic angle twisted bilayer graphene under hydrostatic pressure within a self-consistent Hartree-Fock method in real sp…
Correlated phases and topological phase transition in twisted bilayer graphene at one quantum of magnetic flux
Miguel Sánchez Sánchez, Tobias Stauber
When the perpendicular magnetic flux per unit cell in a crystal is equal to the quantum of magnetic flux, , we enter the 'Hofstadter regime'. The large unit cell of moirÃ…
