Robust translational invariance in topological bands against lattice potentials and disorders
Bo Peng, Nilanjan Roy, Guangyue Ji +1
We theoretically show that the continuous magnetic translational invariance within the Hilbert (sub-)space of a single Landau level (LL) can persist even in the presence of a super…

Operator-state correspondence in simple current extended conformal field theories: Toward a general understanding of chiral conformal field theories and topological orders
Yoshiki Fukusumi, Guangyue Ji, Bo Yang
In this work, we revisit the operator-state correspondence in the Majorana conformal field theory (CFT) with emphasis on its semion representation. Whereas the semion representatio…

Dynamics and lifetime of geometric excitations in moiré systems
Yuzhu Wang, Joe Huxford, Dung Xuan Nguyen +3
We show that spin-2 geometric excitations, known as graviton modes, generally exhibit vanishing lifetimes in lattice Chern bands, including in moiré systems. In contrast to the La…
