Transition from strong to ultra-strong coupling regime in mid-infrared metal-dielectric-metal cavities
Pierre Jouy, Angela Vasanelli, Yanko Todorov +4
We have investigated the transition from strong to ultra-strong coupling regime between a mid-infrared intersubband excitation and the fundamental mode of a metal-dielectric-metal…
A ballistic quantum ring Josephson interferometer
A. Fornieri, M. Amado, F. Carillo +5
We report the realization of a ballistic Josephson interferometer. The interferometer is made by a quantum ring etched in a nanofabricated two-dimensional electron gas confined in…
Spin transition in the fractional quantum Hall regime: Effect of extent of the wave function
V. V. Vanovsky, V. S. Khrapai, A. A. Shashkin +3
Using a magnetocapacitance technique, we determine the magnetic field of the spin transition, B*, at filling factor nu=2/3 in the 2D electron system in GaAs/AlGaAs heterojunctions.…
Imaging backscattering through impurity-induced antidots in quantum Hall constrictions
Nicola Paradiso, Stefan Heun, Stefano Roddaro +6
We exploit the biased tip of a scanning gate microscope (SGM) to induce a controlled backscattering between counter-propagating edge channels in a wide constriction in the quantum…
Energy spectrum reconstruction at the edge of a two-dimensional electron system with strong spin-orbit coupling
A. Kononov, G. Biasiol, L. Sorba +1
We experimentally demonstrate the simultaneous reconstruction of the bulk and the edge energy spectra caused by strong spin-orbit interaction, at the two lowest filling factors $ν=…
Imaging fractional incompressible stripes in integer quantum Hall systems
Nicola Paradiso, Stefan Heun, Stefano Roddaro +5
Transport experiments provide conflicting evidence on the possible existence of fractional order within integer quantum Hall systems. In fact integer edge states sometimes behave a…
Influence of e-e scattering on the temperature dependence of the resistance of a classical ballistic point contact in a two-dimensional electron system
M. Yu. Melnikov, J. P. Kotthaus, V. Pellegrini +3
We experimentally investigate the temperature (T) dependence of the resistance of a classical ballistic point contact (PC) in a two-dimensional electron system (2DES). The split-ga…
