Flat and Topological Floquet Minibands from Patterned Light in Untwisted Bilayer Graphene
Muhammad Faisal, Michael Vogl
Two-dimensional superlattices in van der Waals materials host flat bands and nontrivial topology, most famously at the so-called magic angles of twisted bilayer graphene, where fla…
Fingerprints of an Imbert-Fedorov-like effect in the tunneling transmission of Rarita-Schwinger semi-metals
Otman Bouladiane, Ahmed Jellal, Hocine Bahlouli +2
We study tunneling through a square barrier in a rotationally symmetric Rarita-Schwinger semi-metal and identify fingerprints of an Imbert-Fedorov-like effect in the tunneling tran…
Magnon bandstructure and topology in a periodically deformed Kagome lattice with DM interaction
Mohammed Abdullah Hammadi, Mohammed Salman Alsadah, Husam Abdulmajeed Noorwli +2
We study the band structure and topology of magnons for a Heisenberg model with DM interaction on a deformed Kagome lattice. For simplicity, we focus on a periodically deformed lat…
Band Structure and topology of a periodically deformed Kitaev honeycomb model
Abdullah AlJishi, Ali AlSwaid, Moayad Ekhwan +3
Motivated by the growing interest in spin liquids and topological phases, as well as the rise of deformation engineering, we study the combined effects of deformation and magnetic…
Analytical Treatment of Noise-Suppressed Klein Tunneling in Graphene with Possible Implications for Quantum-Dot Qubits
Kamal Azaidaoui, Ahmed Jellal, Hocine Bahlouli +2
We study quantum tunneling through a potential barrier whose height fluctuates in time and is modeled by Gaussian white noise. We map the stochastic dynamics onto an equivalent tim…
Light induced transitions of valley Chern numbers and flat bands in a non-twisted moire graphene-hexagonal boron nitride superlattice
Saud Alabdulal, Miftah Hadi Syahputra Anfa, Hocine Bahlouli +1
Motivated by the rich topology and interesting quasi-band structure of twisted moire materials subjected to light, we study a non-twisted moire material under the influence of ligh…
