Kondo cloud conductance in cavity-coupled quantum dots with asymmetric barriers
D. Fossion, V. Champain, S. Mohapatra +9
The Kondo effect emerges when a localized spin is screened by conduction electrons, giving rise to a strongly-correlated many-body ground state. In this work, we investigate this p…
Magnetic memory and distinct spin populations in ferromagnetic Co3Sn2S2
Charles Menil, Brigitte Leridon, Antonella Cavanna +7
Co3Sn2S2, a ferromagnetic Weyl semi-metal with Co atoms on a kagome lattice, has generated much recent attention. Experiments have identified a temperature scale below the Curie te…
Thermoelectric Scanning Gate Interferometry on a Quantum Point Contact
B. Brun, F. Martins, S. Faniel +11
We introduce a new scanning probe technique derived from scanning gate microscopy (SGM) in order to investigate thermoelectric transport in two-dimensional semiconductor devices. T…
Electron phase shift at the zero-bias anomaly of quantum point contacts
B. Brun, F. Martins, S. Faniel +11
The Kondo effect is the many-body screening of a local spin by a cloud of electrons at very low temperature. It has been proposed as an explanation of the zero-bias anomaly in quan…
Wigner and Kondo physics in quantum point contacts revealed by scanning gate microscopy
B. Brun, F. Martins, S. Faniel +11
Quantum point contacts exhibit mysterious conductance anomalies in addition to well known conductance plateaus at multiples of 2e^2/h. These 0.7 and zero-bias anomalies have been i…
Quantum coherence engineering in the integer quantum Hall regime
P-A. Huynh, F. Portier, H. le Sueur +6
We present an experiment where the quantum coherence in the edge states of the integer quantum Hall regime is tuned with a decoupling gate. The coherence length is determined by me…
