Identifying Instabilities with Quantum Geometry in Flat Band Systems
Jia-Xin Zhang, Wen O. Wang, Leon Balents +1
The absence of a well-defined Fermi surface in flat-band systems challenges the conventional understanding of instabilities toward Landau order based on nesting. We investigate the…

Chirality and quasi-long-range order in finite-flux Gutzwiller states for magnetized frustrated magnets
Wen O. Wang, Urban F. P. Seifert, Oleg A. Starykh +1
We study Gutzwiller-projected wavefunctions for triangular-lattice U(1) Dirac spin liquids in a Zeeman field, where we allow the U(1) gauge field to develop a gauge flux, resulting…

Topological Chiral Superconductivity in the Triangular-Lattice Hofstadter-Hubbard Model
Feng Chen, Wen O. Wang, Jia-Xin Zhang +2
Moiré materials provide exciting platforms for studying the interplay of strong electronic correlation and large magnetic flux effects. We study the lightly doped Hofstadter-Hubba…
