S Biswas, R Bhattacharyya, HK Kundu, A Das… - Nature physics, 2022 - nature.com
The fractional charge of quasiparticles is a fundamental feature of quantum Hall effect states.
The charge—important in characterizing the state and in interference experiments—has …

Emergence of neutral modes in Laughlin-like fractional quantum Hall phases

U Khanna, M Goldstein, Y Gefen - Physical review letters, 2022 - APS
Chiral gapless boundary modes are characteristic of quantum Hall (QH) states. For hole-
conjugate fractional QH phases counterpropagating edge modes (upstream and …

Monte Carlo simulation of the topological quantities in fractional quantum Hall systems

Y Yang, ZX Hu - Physical Review B, 2023 - APS
Generally speaking, for a fractional quantum Hall (FQH) state, the electronic occupation
number for each Landau orbit could be obtained by numerical methods such as exact …

Edge reconstruction and emergent neutral modes in integer and fractional quantum Hall phases

U Khanna, M Goldstein, Y Gefen - Low Temperature Physics, 2022 - pubs.aip.org
