Microwave-induced conductance replicas in hybrid Josephson junctions without Floquet-Andreev states
D. Z. Haxell, M. Coraiola, D. Sabonis +9
Light-matter interaction enables engineering of non-equilibrium quantum systems. In condensed matter, spatially and temporally cyclic Hamiltonians are expected to generate energy-p…
Deterministic and stochastic sampling of two coupled Kerr parametric oscillators
Gabriel Margiani, Javier del Pino, Toni L. Heugel +6
The vision of building computational hardware for problem optimization has spurred large efforts in the physics community. In particular, networks of Kerr parametric oscillators (K…
Force-detected Magnetic Resonance Imaging of Influenza Viruses in the Overcoupled Sensor Regime
Marc-Dominik Krass, Nils Prumbaum, Raphael Pachlatko +5
Long and thin scanning force cantilevers are sensitive to small forces, but also vulnerable to detrimental non-contact interactions. Here we present an experiment with a cantilever…
Nonlocal conductance spectroscopy of Andreev bound states in gate-defined InAs/Al nanowires
Andreas Pöschl, Alisa Danilenko, Deividas Sabonis +5
The charge character of Andreev bound states (ABSs) in a three-terminal semiconductor-superconductor hybrid nanowire was measured using local and nonlocal tunneling spectroscopy. T…

We investigate local and nonlocal signatures of hybridization between a quantum dot state and an extended Andreev bound state (ABS) in a gate-defined InAs nanowire with multiple si…
Soft-clamped silicon nitride string resonators at millikelvin temperatures
Thomas Gisler, Mohamed Helal, Deividas Sabonis +5
We demonstrate that soft-clamped silicon nitride strings with large aspect ratio can be operated at \si{\milli\kelvin} temperatures. The quality factors () of two measured devic…
Extracting the lifetime of a synthetic two-level system
Gabriel Margiani, Sebastian Guerrero, Toni L. Heugel +11
The Kerr Parametric Oscillator (KPO) is a nonlinear resonator system that is often described as a synthetic two-level system. In the presence of noise, the system switches between…
Strong parametric coupling between two ultra-coherent membrane modes
David Hälg, Thomas Gisler, Eric C. Langman +5
We demonstrate parametric coupling between two modes of a silicon nitride membrane. We achieve the coupling by applying an oscillating voltage to a sharp metal tip that approaches…

Felice Appugliese, Josefine Enkner, Gian Lorenzo Paravicini-Bagliani +6
The control of the electronic properties of materials via the vacuum fields of cavity electromagnetic resonators is one of the emerging frontiers of condensed matter physics. We sh…
Scattering between minivalleys in a moiré material
Petar Tomić, Peter Rickhaus, Aitor Garcia-Ruiz +8
A unique feature of the complex band structures of moiré materials is the presence of minivalleys, their hybridization, and scattering between them. Here we investigate magneto-tra…
