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 Lan…
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…
Quantum metric induced hole dispersion and emergent particle-hole symmetry in topological flat bands
Guangyue Ji, Bo Yang
The emergent hole dispersion in flat bands is an invaluable platform to study the interplay of quantum geometry and electron-electron interaction with a relatively simple setting.…
Universal Modelling of Oscillations in Fractional Quantum Hall Fluids
Guangyue Ji, Koyena Bose, Ajit C. Balram +1
Density oscillations in quantum fluids can reveal their fundamental characteristic features. In this work, we study the density oscillation of incompressible fractional quantum Hal…
