High-Q cryogenic surface acoustic wave resonators in the GHz range
Aldo Tarascio, Oliver Wicki, Dominik M. Zumbühl
Surface acoustic wave (SAW) resonators provide a compact platform for confining microwave-frequency phonons and are widely used in radio-frequency technologies, but their operation…
Compact self-matched gyrators using edge magnetoplasmons
Aldo Tarascio, Yiqi Zhao, Rafael S. Eggli +5
Edge magnetoplasmons provide a natural platform for chiral electrodynamics, where broken time-reversal symmetry enforces unidirectional propagation. When probed at microwave freque…
A scalable non-superconducting tunnel junction technology
Juho Luomahaara, Kristupas Razas, Omid Sharifi Sedeh +15
Tunnel junctions are one of the key elements of chip-scale microsystems serving various technologies from classical microelectronics to quantum information. Aluminium and its oxide…
Magnetic Field-Enhanced Graphene Superconductivity with Record Pauli-Limit Violation
Jixiang Yang, Omid Sharifi Sedeh, Chiho Yoon +22
Spin-polarized superconductors offer a rare platform for studying electronic correlations, but few candidate systems have been experimentally confirmed to date. Here, we report the…
In-situ control of hole-spin driving mechanisms
Simon Geyer, Rafael S. Eggli, Carlos dos Santos +6
Hole-spin qubits enable fast, all-electrical spin manipulation through electric-dipole spin resonance (EDSR), arising from two microscopic mechanisms rooted in their intrinsically…
A direct dispersive signature of Pauli spin blockade
Simon Svab, Rafael S. Eggli, Taras Patlatiuk +7
Pauli Spin Blockade (PSB) is a key paradigm in semiconductor nanostructures and gives access to the spin physics. We report the direct observation of PSB with gate-dispersive refle…
