Whenever a quantum system undergoes a cyclic evolution governed by a slow change of
parameters, it acquires a phase factor: the geometric phase. Its most common formulations …

Fractional charge and fractional statistics in the quantum Hall effects

DE Feldman, BI Halperin - Reports on Progress in Physics, 2021 - iopscience.iop.org
Quasiparticles with fractional charge and fractional statistics are key features of the fractional
quantum Hall effect. We discuss in detail the definitions of fractional charge and statistics …

Anyonic interference and braiding phase in a Mach-Zehnder interferometer

HK Kundu, S Biswas, N Ofek, V Umansky, M Heiblum - Nature physics, 2023 - nature.com
Fractional quantum Hall states have long been predicted to be a testing ground of fractional—
anyonic—exchange statistics. These topological states, which can have either an Abelian or …

Comparing fractional quantum Hall Laughlin and Jain topological orders with the anyon collider

M Ruelle, E Frigerio, JM Berroir, B Plaçais, J Rech… - Physical Review X, 2023 - APS

Stabilization of the particle-hole Pfaffian order by Landau-level mixing and impurities that break particle-hole symmetry

PT Zucker, DE Feldman - Physical Review Letters, 2016 - APS
Numerical results suggest that the quantum Hall effect at ν= 5/2 is described by the Pfaffian
or anti-Pfaffian state in the absence of disorder and Landau-level mixing. Those states are …

Melting of interference in the fractional quantum Hall effect: Appearance of neutral modes

R Bhattacharyya, M Banerjee, M Heiblum, D Mahalu… - Physical Review Letters, 2019 - APS
We attempted to measure interference of the outer edge mode in the fractional quantum hall
regime with an electronic Mach-zehnder interferometer. The visibility of the interferometer …

Current correlations from a mesoscopic anyon collider

B Rosenow, IP Levkivskyi, BI Halperin - Physical Review Letters, 2016 - APS
Fermions and bosons are fundamental realizations of exchange statistics, which governs the
