Experimental realization of Laughlin quasiparticle interferometers
F. E. Camino, Wei Zhou, V. J. Goldman
Laughlin quasiparticles are the elementary excitations of a highly-correlated fractional quantum Hall electron fluid. They have fractional charge and obey fractional statistics. Th…
Quantum transport in electron Fabry-Perot interferometers
F. E. Camino, Wei Zhou, V. J. Goldman
We report experiments on Fabry-Perot electron interferometers in the integer quantum Hall regime. The GaAs/AlGaAs heterostructure devices consist of two constrictions defined by et…
Experimental realization of a primary-filling e/3 quasiparticle interferometer
F. E. Camino, Wei Zhou, V. J. Goldman
We report experiments on a Laughlin quasiparticle interferometer where the entire system is on the 1/3 primary fractional quantum Hall plateau. Electron-beam lithography is used to…
Thermal Dephasing in the Laughlin Quasiparticle Interferometer: Chiral Luttinger Liquid Behavior
F. E. Camino, W. Zhou, V. J. Goldman
We report experimental temperature dependence of the amplitude of Aharonov-Bohm oscillations in the Laughlin quasiparticle interferometer. The results fit very well the thermal dep…
