Quantized and nonquantized Hall response in topological Hatsugai-Kohmoto systems
Thibaut Desort, Mark O. Goerbig, Corentin Morice
We explore the robustness of Hall conductivity quantization in several insulating systems, exhibiting one scenario where the quantization is not preserved. Specifically, we apply t…
Beating Fabry-Pérot interference pattern in a magnonic scattering junction in the graphene quantum Hall ferromagnet
Jonathan Atteia, Preden Roulleau, Mark O. Goerbig
At filling factor , the ground state of graphene is a particular SU(4) ferromagnet which hosts a rich phase diagram along with several spin, pseudospin or "entanglement"…
Berry curvature contribution towards interlayer exciton ultrafast transition within a heterobilayer
Houssem Eddine Hannachi, Mark-Oliver Goerbig, Sihem Jaziri
We calculate the spectrum of interlayer neutral excitons in transition-metal-dichalcogenide WeSe/MoSe heterobilayers in the -stacking configuration. Most saliently, we s…
Helical trilayer graphene in magnetic field: Chern mosaic and higher Chern number ideal flat bands
Anushree Datta, Daniele Guerci, Mark O. Goerbig +1
Helical trilayer graphene (hTG) exhibits a supermoiré pattern with large domains centered around stacking points ABA and BAB, where two well-separated low-energy bands appear with…
Normal state quantum geometry and superconducting domes in (111) oxide interfaces
Florian Simon, Mark O. Goerbig, Marc Gabay
We theoretically investigate the influence of the normal state quantum geometry on the superconducting phase in (111) oriented oxide interfaces and discuss some of the implications…
