Nonlocal correlations of the local density of states in disordered quantum Hall systems
T. Champel, S. Florens, M. E. Raikh
Motivated by recent high-resolution scanning tunneling microscopy (STM) experiments in the quantum Hall regime both on massive two-dimensional electron gas and on graphene, we cons…
`Deterministic' quantum plasmonics
Aurélien Cuche, Oriane Mollet, Aurélien Drezet +1
We demonstrate `deterministic' launching of propagative quantum surface-plasmon polaritons at freely chosen positions on gold plasmonic receptacles. This is achieved by using as pl…
Imaging Coulomb Islands in a Quantum Hall Interferometer
B. Hackens, F. Martins, S. Faniel +7
In the Quantum Hall regime, near integer filling factors, electrons should only be transmitted through spatially-separated edge states. However, in mesoscopic systems, electronic t…
Spin transition in GdN@C, detected by low-temperature on-chip SQUID technique
L. Chen, E. E. Carpenter, C. S. Hellberg +4
We present a magnetic study of the GdN@C molecule, consisting of a Gd-trimer via a Nitrogen atom, encapsulated in a C cage. This molecular system can be an effici…
On-chip SQUID measurements in the presence of high magnetic fields
L. Chen, W. Wernsdorfer, C. Lampropoulos +2
We report a low temperature measurement technique and magnetization data of a quantum molecular spin, by implementing an on-chip SQUID technique. This technique enables the SQUID m…
Hybrid superconductor-semiconductor devices made from self-assembled SiGe nanocrystals on silicon
G. Katsaros, P. Spathis, M. Stoffel +7
The epitaxial growth of germanium on silicon leads to the self-assembly of SiGe nanocrystals via a process that allows the size, composition and position of the nanocrystals to be…
