Beyond the Flat-Band Paradigm: Open Orbits as a Route to Correlated States in Dispersive Moiré Minibands
Zihao Wang, Pablo M. Perez-Piskunow, Calvin Pei Yu Wong +16
The realization of fractional Chern insulators has largely relied on isolated flat bands in complex bilayer or multilayer moiré systems with ideal quantum geometry. Whether such ph…
Spin-orbit coupling-enhanced valley ordering of malleable bands in twisted bilayer graphene on WSe2
Saisab Bhowmik, Bhaskar Ghawri, Youngju Park +8
New phases of matter can be stabilized by a combination of diverging electronic density of states, strong interactions, and spin-orbit coupling. Recent experiments in magic-angle t…

To determine the topological quantum numbers of fractional quantum Hall (FQH) states hosting counter-propagating (CP) downstream () and upstream () edge modes, it is pivo…
Zero-field superconducting diode effect in small-twist-angle trilayer graphene
Jiang-Xiazi Lin, Phum Siriviboon, Harley D. Scammell +7
The critical current of a superconductor can be different for opposite directions of current flow when both time-reversal and inversion symmetry are broken. %When time-reversal and…
