Theory of intervalley-coherent AFM order and topological superconductivity in tWSe
Ammon Fischer, Lennart Klebl, Valentin Crépel +7
The recent observation of superconductivity in the vicinity of Fermi surface reconstructed insulating or metallic states has established twisted bilayers of WSe\textsubscript{2} as…
Charge transfer spin-polarons and ferromagnetism in weakly doped AB-stacked TMD heterobilayers
Daniele Guerci, J. H. Pixley, Andrew J. Millis
We study the formation of ferromagnetic and magnetic polaron states in weakly doped heterobilayer transition metal dichalcogenides in the ``heavy fermion'' limit in which one layer…
Anyon Superconductivity from Topological Criticality in a Hofstadter-Hubbard Model
Stefan Divic, Valentin Crépel, Tomohiro Soejima +4
We argue that the combination of strong repulsive interactions and high magnetic fields can generate electron pairing and superconductivity. Inspired by the large lattice constants…
Topological superconductivity from repulsive interactions in twisted WSe
Daniele Guerci, Daniel Kaplan, Julian Ingham +2
The recent observation of superconductivity in twisted bilayer WSe raises intriguing questions concerning the origin and the properties of superconducting states realized in ba…
Topological Kondo semimetal and insulator in AB-stacked heterobilayer transition metal dichalcogenides
Daniele Guerci, Kevin P. Lucht, Valentin Crépel +3
Recent experiments reported the realization of a heavy Fermi liquid in AB-stacked MoTe/WSe heterobilayers. In this paper we show that the AB-stacked heterobilayer configura…
Spinon pairing induced by chiral in-plane exchange and the stabilization of odd-spin Chern number spin liquid in twisted
Valentin Crépel, Andrew Millis
The unusual structure and symmetry of low-energy states in twisted transition metal dichalcogenides leads to large in-plane spin-exchange interactions between spin-valley locked ho…
Chiral Spin Liquid and Quantum Phase Transition in the Triangular Lattice Hofstadter-Hubbard Model
Stefan Divic, Tomohiro Soejima, Valentin Crépel +2
Recent advances in moiré engineering motivate the study of lattice models of strongly-correlated electrons subjected to substantial orbital magnetic flux. We analyze the triangular…
Bridging the small and large in twisted transition metal dicalcogenide homobilayers: a tight binding model capturing orbital interference and topology across a wide range of twist angles
Valentin Crépel, Andrew Millis
Many of the important phases observed in twisted transition metal dichalcogenide homobilayers are driven by short-range interactions, which should be captured by a local tight bind…
