Topological Robustness of Anyon Tunneling at
Adithya Suresh, Ramon Guerrero-Suarez, Tanmay Maiti +4
The scaling exponent of the quasiparticle propagator for incompressible fractional quantum Hall states in the Laughlin sequence is expected to be robust against perturbations t…
Collapse of edge reconstruction in compressible Quantum Hall fluid within filling fraction range 2/3 to 1
Suvankar Purkait, Tanmay Maiti, Pooja Agarwal +4
The edge structure of a gate-defined compressible quantum Hall fluids in the filling fraction range 2/3 to 1 is studied using the three reconstructed fractional edge modes…
Universal Anyon Tunneling in a Chiral Luttinger Liquid
Ramon Guerrero-Suarez, Adithya Suresh, Tanmay Maiti +5
The edge modes of fractional quantum Hall liquids are described by chiral Luttinger liquid theory. Despite many years of experimental investigation fractional quantum Hall edge mod…
Edge reconstruction of compressible Quantum Hall fluid in the filling fraction range 1/3 to 2/3
Suvankar Purkait, Tanmay Maiti, Pooja Agarwal +6
Edge reconstruction of gate-tunable compressible quantum Hall fluids in the filling fraction range 1/3 to 2/3 is studied by measuring transmitted conductance of two individually ex…
Optimization of submicron Ni/Au/Ge contacts to an AlGaAs/GaAs two-dimensional electron gas
Matthew Mann, James Nakamura, Shuang Liang +3
We report on fabrication and performance of submicron Ni/Au/Ge contacts to a two-dimensional electron gas in an AlGaAs/GaAs heterostructure. Utilizing scanning transmission electro…
