Strongly coupled ultracompressed self-cavity plasmon polaritons at millikelvin temperatures
Luojia Zhang, Andrew T. Pierce, Xuepeng Wang +7
Van der Waals heterostructures exhibit self-cavity resonances from sub-terahertz to terahertz frequencies and thus offer an attractive route toward realizing cavity-modified phases…
Origin of the superconductor-insulator transition in disordered two-dimensional films
Alexander Weitzel, Lea Pfaffinger, Animesh Panda +8
Theory predicts the superconductor-to-insulator transition (SIT) to emerge from the competition between Anderson localization, which tends to localize single-particle wavefunctions…
Krypton-sputtered tantalum films for scalable high-performance quantum devices
Maciej W. Olszewski, Lingda Kong, Simon Reinhardt +9
Superconducting qubits based on tantalum (Ta) thin films have demonstrated the highest-performing microwave resonators and qubits. This makes Ta an attractive material for supercon…
Spontaneous supercurrents and vortex depinning in two-dimensional arrays of -junctions
Simon Reinhardt, Alexander-Georg Penner, Johanna Berger +9
Two-dimensional arrays of ballistic Josephson junctions are important as model systems for synthetic quantum materials. Here, we investigate arrays of multiterminal junctions which…
Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry
Simon Reinhardt, Tim Ascherl, Andreas Costa +9
In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…
Sign reversal of the AC and DC supercurrent diode effect and 0--like transitions in ballistic Josephson junctions
Andreas Costa, Christian Baumgartner, Simon Reinhardt +9
The recent discovery of intrinsic supercurrent diode effect, and its prompt observation in a rich variety of systems, has shown that nonreciprocal supercurrents naturally emerge wh…
Anisotropic vortex squeezing in synthetic Rashba superconductors: a manifestation of Lifshitz invariants
Lorenz Fuchs, Denis Kochan, Christian Baumgartner +7
Most of 2D superconductors are of type II, i.e., they are penetrated by quantized vortices when exposed to out-of-plane magnetic fields. In presence of a supercurrent, a Lorentz-li…
Effect of Rashba and Dresselhaus spin-orbit coupling on supercurrent rectification and magnetochiral anisotropy of ballistic Josephson junctions
Christian Baumgartner, Lorenz Fuchs, Andreas Costa +11
Simultaneous breaking of inversion- and time-reversal symmetry in Josephson junction leads to a possible violation of the equality for the current-phase relation. Thi…
A Josephson junction supercurrent diode
Christian Baumgartner, Lorenz Fuchs, Andreas Costa +10
Transport is called nonreciprocal when not only the sign, but also the absolute value of the current, depends on the polarity of the applied voltage. It requires simultaneously bro…
Josephson inductance as a probe for highly ballistic semiconductor-superconductor weak links
Christian Baumgartner, Lorenz Fuchs, Linus Frész +6
We present simultaneous measurements of Josephson inductance and DC transport characteristics of ballistic Josephson junctions based upon an epitaxial Al-InAs heterostructure. The…
Coulomb Blockade Spectroscopy of a Nanotube
Simon Reinhardt, Luka Pirker, Christian Bäuml +2
Low-temperature transport spectroscopy measurements on a quantum dot lithographically defined in a multiwall nanotube are demonstrated. At , cl…
Lab::Measurement - A portable and extensible framework for controlling lab equipment and conducting measurements
S. Reinhardt, C. Butschkow, S. Geissler +5
Lab::Measurement is a framework for test and measurement automatization using Perl 5. While primarily developed with applications in mesoscopic physics in mind, it is widely adapta…
