Signatures of Dynes superconductivity in the THz response of ALD-grown NbN thin films
Frederik Bolle, Yayi Lin, Ozan Saritas +6
The frequency-dependent complex optical conductivity reflects key properties of superconductors, such as the energy gap in the density of states (DOS) and the superfluid density. F…
Quartet currents in a biased three-terminal diffusive Josephson junction
T. Jonckheere, J. Rech, C. Padurariu +3
Biasing a three-terminal Josephson junction (TTJ) with symmetrical voltages leads to new kinds of DC currents, namely quartet Josephson currents and phase-dependent multip…
Tracking a Spin-Polarized Superconducting Bound State across a Quantum Phase Transition
Sujoy Karan, Haonan Huang, Alexander Ivanovic +5
The magnetic exchange coupling between magnetic impurities and a superconductor induce so-called Yu-Shiba-Rusinov (YSR) states which undergo a quantum phase transition (QPT) upon i…
Microwave Excitation of Atomic Scale Superconducting Bound States
Janis Siebrecht, Haonan Huang, Piotr Kot +6
Magnetic impurities on superconductors lead to bound states within the superconducting gap, so called Yu-Shiba-Rusinov (YSR) states. They are parity protected, which enhances their…
Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Haonan Huang, Sujoy Karan, Ciprian Padurariu +5
Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlat…
Emission of photon multiplets by a dc-biased superconducting circuit
G. C. Ménard, A. Peugeot, C. Padurariu +12
We observe the emission of bunches of photons by a circuit made of a microwave resonator in series with a voltage-biased tunable Josephson junction. The bunches are…
Superconducting Quantum Interference at the Atomic Scale
S. Karan, H. Huang, C. Padurariu +9
A single spin in a Josephson junction can reverse the flow of the supercurrent. At mesoscopic length scales, such -junctions are employed in various instances from finding the p…
Spin-dependent tunneling between individual superconducting bound states
Haonan Huang, Jacob Senkpiel, Ciprian Padurariu +9
Magnetic impurities on superconductors induce discrete bound levels inside the superconducting gap, known as Yu-Shiba-Rusinov (YSR) states. YSR levels are fully spin-polarized such…
Tunneling dynamics between superconducting bound states at the atomic limit
Haonan Huang, Ciprian Padurariu, Jacob Senkpiel +7
Despite plenty of room at the bottom, there is a limit to the miniaturization of every process. For charge transport this is realized by the coupling of single discrete energy leve…
Magnetic Impurities on Superconducting Surfaces: Phase Transitions and the Role of Impurity-Substrate Hybridization
Haonan Huang, Robert Drost, Jacob Senkpiel +7
Spin-dependent scattering from magnetic impurities inside a superconductor gives rise to Yu-Shiba-Rusinov (YSR) states within the superconducting gap. As such, YSR states have been…
Single Channel Josephson Effect in a High Transmission Atomic Contact
Jacob Senkpiel, Simon Dambach, Markus Etzkorn +9
The Josephson effect in scanning tunneling microscopy (STM) is an excellent tool to probe the properties of the superconducting order parameter on a local scale through the Ambegao…
Robustness of Yu-Shiba-Rusinov resonances in presence of a complex superconducting order parameter
Jacob Senkpiel, Carmen Rubio-Verdú, Markus Etzkorn +8
Robust quantum systems rely on having a protective environment with minimized relaxation channels. Superconducting gaps play an important role in the design of such environments. T…
