On modeling quantum point contacts in quantum Hall systems
Prasoon Kumar, Kyrylo Snizhko
Quantum point contacts (QPC) are a key instrument in investigating the physics of edge excitations in the quantum Hall effect. However, at not-so-high bias voltage values, the pred…
Scaling tunnelling noise in the fractional quantum Hall effect tells about renormalization and breakdown of chiral Luttinger liquid
Noam Schiller, Tomer Alkalay, Changki Hong +4
The fractional quantum Hall (FQH) effect provides a paradigmatic example of a topological phase of matter. FQH edges are theoretically described via models belonging to the class o…
Extracting the scaling dimension of quantum Hall quasiparticles from current correlations
Noam Schiller, Yuval Oreg, Kyrylo Snizhko
Fractional quantum Hall quasiparticles are generally characterized by two quantum numbers: electric charge and scaling dimension . For the simplest states (such as the Laugh…
Energy relaxation in edge modes in the quantum Hall effect
Amir Rosenblatt, Sofia Konyzheva, Fabien Lafont +6
Studies of energy flow in quantum systems complement the information provided by common conductance measurements. The quantum limit of heat flow in one dimensional (1D) ballistic m…
Non-Abelian Berry phase for open quantum systems: Topological protection vs geometric dephasing
Kyrylo Snizhko, Reinhold Egger, Yuval Gefen
We provide a detailed theoretical analysis of the adiabatic evolution of degenerate open quantum systems, where the dynamics is induced by time-dependent fluctuating loop paths in…
Non-Abelian Geometric Dephasing
Kyrylo Snizhko, Reinhold Egger, Yuval Gefen
We study the adiabatic dynamics of degenerate quantum states induced by loop paths in a control parameter space. The latter correspond to noisy trajectories if the system is weakly…
Universal quantum noise in adiabatic pumping
Yaroslav Herasymenko, Kyrylo Snizhko, Yuval Gefen
We consider charge pumping in a system of parafermions, implemented at fractional quantum Hall edges. Our pumping protocol leads to a noisy behavior of the pumped current. As the a…
