Band structure and band topology in twisted homotrilayer transition metal dichalcogenides
Hassan AlBuhairan, Michael Vogl
We investigate a simplified continuum model of a twisted homotrilayer TMD with negligible next-nearest layer couplings. We systematically analyze band structure and topology of var…
Tunneling phase diagrams in anisotropic Multi-Weyl semimetals
Ahmed Bouhlal, Adel Abbout, Ahmed Jellal +2
Motivated by the exciting prediction of Multi-Weyl topological semimetals that are stabilized by point group symmetries [Phys. Rev. Lett. 108 (2012) 266802], we study tunneling phe…
Chiral limits and effect of light on the Hofstadter butterfly in twisted bilayer graphene
Nadia Benlakhouy, Ahmed Jellal, Hocine Bahlouli +1
We study the magnetic field induced Hofstadter butterfly in twisted bilayer graphene (TBG) in various kinds of situations. First, we study the equilibrium case and identify the int…

Motivated by the recent experimental realization of twisted double bilayer graphene (TDBG) samples we study, both analytically and numerically, the effects of circularly polarized…
Effective Floquet Hamiltonians for periodically-driven twisted bilayer graphene
Michael Vogl, Martin Rodriguez-Vega, Gregory A. Fiete
We derive effective Floquet Hamiltonians for twisted bilayer graphene driven by circularly polarized light in two different regimes beyond the weak-drive, high frequency regime. Fi…
Floquet engineering of interlayer couplings: Tuning the magic angle of twisted bilayer graphene at the exit of a waveguide

We introduce a new approach that allows one complete control over the modulation of the effective twist angle change in few-layer van der Waals heterostructures by irradiating them…
Effective Floquet Hamiltonian in the low-frequency regime
Michael Vogl, Martin Rodriguez-Vega, Gregory A. Fiete
We develop a theory to derive effective Floquet Hamiltonians in the weak drive and low-frequency regime. We construct the theory in analogy with band theory for electrons in a spat…
