Irradiating normal-superconducting junctions with microwave photons produce spectacular effects, such as Shapiro steps and photoinduced modifications of the dc supercurrent. Moreover, microwave irradiation can also have other, hitherto unexplored con

We probe the high frequency emission of a carbon nanotube based Josephson junction and compare it to its DC Josephson current. The AC emission is probed by coupling the carbon nanotube to an on-chip detector (a Superconductor-Insulator-Superconductor

We have probed the superconducting proximity effect through long high-quality monocrystalline Ag nanowires, by realizing Josephson junctions of different lengths, with different superconducting materials. Thanks to the high number of junctions probed

0−πQuantum transition in a carbon nanotube Josephson junction: Universal phase dependence and orbital degeneracy

Autor: Meydi Ferrier, R. Weil, R. Deblock, A. Kasumov, Hélène Bouchiat, Raphaelle Delagrange

Publikováno v: Physica B: Condensed Matter. 536:211-222

In a quantum dot hybrid superconducting junction, the behavior of the supercurrent is dominated by Coulomb blockade physics, which determines the magnetic state of the dot. In particular, in a single level quantum dot singly occupied, the sign of the

Fatherhood Experiences of Men With Inflammatory Arthritis: A Preliminary Grounded Theory

Autor: Michal Avrech Bar, Catherine L. Backman, Thao T. Dao, Leah R. DeBlock Vlodarchyk

Publikováno v: Arthritis careresearchReferences. 73(6)

Objective Minimal prior research has examined the impact of inflammatory arthritis (IA) on men's perspectives on parenting. We aim to describe fathering roles and experiences, the effect of IA on parenting activities, and strategies used by fathers w

Enhanced Shot Noise of Multiple Andreev Reflections in a Carbon Nanotube Quantum Dot in SU(2) and SU(4) Kondo regimes

Publikováno v: Physical Review Letters
Physical Review Letters, American Physical Society, 2018, 121 (24), ⟨10.1103/PhysRevLett.121.247703⟩

The sensitivity of shot noise to the interplay between Kondo correlations and superconductivity is investigated in a carbon nanotube quantum dot connected to superconducting electrodes. Depending on the gate voltage, the SU(2) and SU(4) Kondo unitary
