Organizing Principles for Moiré Quantum Matter
Qiaoling Xu, Yifan Gao, Tao Zhang +16
Moiré flat bands in van der Waals bilayers are usually discussed through a small set of mechanisms associated with the and valleys of hexagonal crystals, and more recentl…
Angle evolution of the superconducting phase diagram in twisted bilayer WSe2
Yinjie Guo, John Cenker, Ammon Fischer +13
Recent observations of superconductivity in twisted bilayer WSe have extended the family of moiré superconductors beyond twisted graphene. In WSe two different twist angle…
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…
Engineering 2D square lattice Hubbard models in 90 twisted Ge/SnX (X=S, Se) moiré supperlattices
Qiaoling Xu, Ammon Fischer, Nicolas Tancogne-Dejean +6
Due to the large-period superlattices emerging in moire two-dimensional (2D) materials, electronic states in such systems exhibit low energy flat bands that can be used to simulate…
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…
Polaritonic Quantum Matter
D. N. Basov, A. Asenjo-Garcia, P. J. Schuck +6
Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light-matter admixture causes a characteristic frequency-…
