Unveiling the bosonic nature of an ultrashort few-electron pulse
Gregoire Roussely, Everton Arrighi, Giorgos Georgiou +10
Quantum dynamics is very sensitive to dimensionality. While two-dimensional electronic systems form Fermi liquids, one-dimensional systems -- Tomonaga-Luttinger liquids -- are desc…
Non-universal transmission phase behaviour of a large quantum dot
H. Edlbauer, S. Takada, G. Roussely +6
The electron wave function experiences a phase modification at coherent transmission through a quantum dot. This transmission phase undergoes a characteristic shift of when sca…
Highly efficient spin-to-charge current conversion at room temperature in strained HgTe surface states
P. Noël, C. Thomas, Y. Fu +7
We report the observation of spin-to-charge current conversion in strained mercury telluride at room temperature, using spin pumping experiments. The conversion rates are found to…
A linear triple quantum dot system in isolated configuration
Hanno Flentje, Benoit Bertrand, Pierre-André Mortemousque +4
The scaling up of electron spin qubit based nanocircuits has remained challenging up to date and involves the development of efficient charge control strategies. Here we report on…
Revealing topological Dirac fermions at the surface of strained HgTe thin films via Quantum Hall transport spectroscopy
C. Thomas, O. Crauste, B. Haas +7
We demonstrate evidences of electronic transport via topological Dirac surface states in a thin film of strained HgTe. At high perpendicular magnetic fields, we show that the elect…
Coherent long-distance displacement of individual electron spins
H. Flentje, P-A. Mortemousque, R. Thalineau +4
Controlling nanocircuits at the single electron spin level is a possible route for large-scale quantum information processing. In this context, individual electron spins have been…
