Interplay of coupling, residual, and quasiparticle losses for the frequency- and temperature-dependent quality factor of superconducting resonators
Elies Ben Achour, Cenk Beydeda, Gabriele Untereiner +2
The overall, loaded quality factor quantifies the loss of energy stored in a resonator. Here we discuss on general grounds how of a planar microwave r…

Gapped magnetic ground state in the spin-liquid candidate -(BEDT-TTF)Ag(CN) suggested by magnetic spectroscopy
Sudip Pal, Björn Miksch, Hans-Albrecht Krug von Nidda +10
The nature of the magnetic ground state of highly frustrated systems remained puzzling to this day. Here, we have performed multifrequency electron spin resonance (ESR) measurement…

Tuning the superconducting dome in granular aluminum thin films
Aniruddha Deshpande, Jan Pusskeiler, Christian Prange +3
Granular aluminum, which consists of nanometer-sized aluminum grains separated by aluminum oxide, is a peculiar superconductor. Its phase diagram as function of normal-state resist…
