Site-polarized Mott phases competing with a correlated metal in twisted WSe
Siheon Ryee, Lennart Klebl, Gautam Rai +9
Twisted WSe hosts superconductivity, metal-insulator phase transitions, and field-controllable Fermi-liquid to non-Fermi-liquid transport properties. In this work, we use dynam…
Real-Space Switching of Local Moments Driven by Quantum Geometry in Correlated Graphene Heterostructures
Niklas Witt, Siheon Ryee, Lennart Klebl +3
Graphene-based multilayer systems serve as versatile platforms for exploring the interplay between electron correlation and topology, thanks to distinctive low-energy bands marked…
Electronic correlations in epitaxial graphene: Mott states proximitized to a relativistic electron gas
Chitran Ghosal, Siheon Ryee, Zamin Mamiyev +3
Graphene, renowned for its exceptional electronic and optical properties as a robust 2D material, traditionally lacks electronic correlation effects. Proximity coupling offers a pr…
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…
Switching between Mott-Hubbard and Hund physics in moiré quantum simulators
Siheon Ryee, Tim O. Wehling
Mott-Hubbard and Hund electron correlations have been realized thus far in separate classes of materials. Here, we show that a single moiré homobilayer encompasses both kinds of ph…
Frozen spin ratio and the detection of Hund correlations
Siheon Ryee, Sangkook Choi, Myung Joon Han
We propose a way to identify strongly Hund-correlated materials by unveiling a key signature of Hund correlations at the two-particle level. The defining feature is the {\it sign}…
