Does shot noise always provide the quasiparticle charge?
Sourav Biswas, Rajarshi Bhattacharyya, Hemanta Kumar Kundu +5
The fractional charge of quasiparticles is a fundamental feature of quantum Hall effect (QHE) States. The charge has long been measured via shot-noise at moderate temperatures (…
Measurement-driven navigation in many-body Hilbert space: Active-decision steering
Yaroslav Herasymenko, Igor Gornyi, Yuval Gefen
The challenge of preparing a system in a designated state spans diverse facets of quantum mechanics. To complete this task of steering quantum states, one can employ quantum contro…
Emergence of Neutral Modes in Laughlin-like Fractional Quantum Hall Phases
Udit Khanna, Moshe Goldstein, Yuval Gefen
Chiral gapless boundary modes are characteristic of quantum Hall (QH) states. For hole-conjugate fractional QH phases counterpropagating edge modes (upstream and downstream) are ex…
Parafermions in a multilegged geometry: Towards a scalable parafermionic network
Udit Khanna, Moshe Goldstein, Yuval Gefen
Parafermionic zero modes are non-Abelian excitations which have been predicted to emerge at the boundary of topological phases of matter. Contrary to earlier proposals, here we sho…
Edge Reconstruction of a Time-Reversal Invariant Insulator: Compressible-Incompressible Stripes
Udit Khanna, Yuval Gefen, Ora Entin-Wohlman +1
Two-dimensional (2D) topological electronic insulators are known to give rise to gapless edge modes, which underlie low energy dynamics, including electrical and thermal transport.…
Near-frozen non-equilibrium state at high energy in an integrable system
Stefan G. Fischer, Yigal Meir, Yuval Gefen +1
Ergodic many-body systems are expected to reach quasi-thermal equilibrium. Here we demonstrate that, surprisingly, high-energy electrons, which are injected into a quantum Hall edg…
