Low-frequency and Moiré Floquet engineering: a review
Martin Rodriguez-Vega, Michael Vogl, Gregory A. Fiete
We review recent work on low-frequency Floquet engineering and its application to quantum materials driven by light, emphasizing van der Waals systems hosting Moiré superlattices.…
Floquet-engineering topological transitions in a twisted transition metal dichalcogenide homobilayer
Michael Vogl, Martin Rodriguez-Vega, Benedetta Flebus +2
Motivated by the recent experimental realization of twisted transition metal dichalcogenide bilayers, we study a simplified model driven by different forms of monochromatic light.…
Direct driving of electronic and phononic degrees of freedom in a honeycomb bilayer with infrared light
Martin Rodriguez-Vega, Michael Vogl, Gregory A. Fiete
We study theoretically AB-stacked honeycomb bilayers driven by light in resonance with an infrared phonon within a tight-binding description. We characterize the phonon properties…
Group theory study of the vibrational modes and magnetic order in the topological antiferromagnet MnBiTe
Martin Rodriguez-Vega, A. Leonardo, Gregory A. Fiete
We employ group theory to study the properties of the lattice vibrations and magnetic order in the antiferromagnetic topological insulator MnBiTe, both in bulk and few-laye…
Floquet engineering of twisted double bilayer graphene
Martin Rodriguez-Vega, Michael Vogl, Gregory A. Fiete
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…
Discovery of the soft electronic modes of the trimeron order in magnetite
Edoardo Baldini, Carina A. Belvin, Martin Rodriguez-Vega +9
The Verwey transition in magnetite (FeO) is the first metal-insulator transition ever observed and involves a concomitant structural rearrangement and charge-orbital orderi…
Floquet engineering of interlayer couplings: Tuning the magic angle of twisted bilayer graphene at the exit of a waveguide
Michael Vogl, Martin Rodriguez-Vega, Gregory A. Fiete
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…
