Constriction-induced modulation of charging energy in a quantum Hall cavity
Emily Hajigeorgiou, Arup Kumar Paul, Mario Di Luca +3
Electronic Fabry-Pérot interferometers (FPIs) operating in the fractional quantum Hall regime are a key platform for probing anyonic braiding statistics, yet interpreting their in…
Observation of e/4 charge at in GaAs
Tomer Alkalai, Emily Hajigeorgiou, Adbhut Gupta +9
Even-denominator fractional quantum Hall states (FQHSs) fall outside the standard Laughlin's and Jain's odd-denominator hierarchy. In this work, we study the FQHS in the l…
Quantum Hall Antidot as a Fractional Coulombmeter
Mario Di Luca, Emily Hajigeorgiou, Zekang Zhou +6
The detection of fractionally charged quasiparticles, which arise in the fractional quantum Hall regime, is of fundamental importance for probing their exotic quantum properties. W…
Tunable Inter-Edge Interactions in a Bilayer Graphene Quantum Hall Antidot
Mario Di Luca, Emily Hajigeorgiou, Zekang Zhou +5
Electronic interferometers in the quantum Hall regime are one of the best tools to study the statistical properties of localized quasiparticles in the topologically protected bulk.…
Featuring nuanced electronic band structure in gapped multilayer graphene
Jin Jiang, Qixuan Gao, Zekang Zhou +6
Moiré systems featuring flat electronic bands exhibit a vast landscape of emergent exotic quantum states, making them one of the resourceful platforms in condensed matter physics…
