Optomechanical microwave amplification without mechanical amplification
Martijn A. Cohen, Daniel Bothner, Yaroslav M. Blanter +1
High-gain and low-noise signal amplification is a valuable tool in various cryogenic microwave experiments. A microwave optomechanical device, in which a vibrating capacitor modula…
Bimodal Phase Diagram of the Superfluid Density in LaAlO3/SrTiO3 Revealed by an Interfacial Waveguide Resonator
Nicola Manca, Daniel Bothner, Ana M. R. V. L. Monteiro +6
We explore the superconducting phase diagram of the two-dimensional electron system at the LaAlO3/SrTiO3 interface by monitoring the frequencies of the cavity modes of a coplanar w…
Superconducting coplanar microwave resonators with operating frequencies up to 50 GHz
Desirée S. Rausch, Markus Thiemann, Martin Dressel +4
We demonstrate the operation of superconducting coplanar microwave resonators in a very large frequency range up to 50 GHz. The resonators are fabricated from niobium thin films on…
Tunable superconducting two-chip lumped element resonator
Benedikt Ferdinand, Daniel Bothner, Reinhold Kleiner +1
We have fabricated and investigated a stacked two-chip device, consisting of a lumped element resonator on one chip, which is side-coupled to a coplanar waveguide transmission line…
