Magnetic-field dependent vortex dynamics and critical currents in superconducting microwires with regular large-area perforation by pinholes
Dong Zhu, Ilya Charaev, Konstantin Ilin +1
We report on results of simulations and experiments of vortex states in superconducting micro-wires with periodic rectangular pinhole structures. The simulations have been performe…
First Sub-MeV Dark Matter Search with the QROCODILE Experiment Using Superconducting Nanowire Single-Photon Detectors
Laura Baudis, Alexander Bismark, Noah Brugger +15
We present the first results from the Quantum Resolution-Optimized Cryogenic Observatory for Dark matter Incident at Low Energy (QROCODILE). The QROCODILE experiment uses a microwi…
Low-Temperature Heat Transport under Phonon Confinement in Nanostructures
M. Sidorova, A. D. Semenov, A. Zaccone +5
Heat transport in bulk materials is well described using the Debye theory of 3D vibrational modes (phonons) and the acoustic match model. However, in cryogenic nanodevices, phonon…
Fundamental limits of few-layer NbSe microbolometers at terahertz frequencies
K. Shein, E. Zharkova, M. A. Kashchenko +11
The rapid development of infrared spectroscopy, observational astronomy, and scanning near-field microscopy has been enabled by the emergence of sensitive mid- and far-infrared pho…
Single-photon detection using large-scale high-temperature MgB sensors at 20 K
I. Charaev, E. K. Batson, S. Cherednichenko +10
Ultra-fast single-photon detectors with high current density and operating temperature can benefit space and ground applications, including quantum optical communication systems, l…
Heat flowing from cold to hot without external intervention by using a 'thermal inductor'
Andreas Schilling, Xiaofu Zhang, Olaf Bossen
The cooling of boiling water all the way down to freezing, by thermally connecting it to a thermal bath held at ambient temperature without external intervention, would be quite un…
Superconducting single X-ray photon detector based on W0.8Si0.2
X. Zhang, Q. Wang, A. Schilling
We fabricated a superconducting single X-ray photon detector based on W0.8Si0.2, and we characterized its basic detection performance for keV-photons at different temperatures. The…
Characteristics of superconducting tungsten silicide WxSi1-x for single photon detection
X. Zhang, A. Engel, Q. Wang +7
Superconducting properties of three series of amorphous WxSi1-x films with different thickness and stoichiometry were investigated by dc transport measurements in a magnetic field…
Temperature-dependence of detection efficiency in NbN and TaN SNSPD
Andreas Engel, Kevin Inderbitzin, Andreas Schilling +7
We present systematic measurements of the temperature-dependence of detection efficiencies in TaN and NbN superconducting nanowire single-photon detectors. We have observed a clear…
Differential-thermal analysis around and below the critical temperature Tc of various low-Tc superconductors: A comparative study
M. Reibelt, A. Schilling, P. C. Canfield +2
We present specific-heat data on the type-II superconductors V3Si, LuNi2B2C and NbSe2 which were acquired with a low-temperature thermal analysis (DTA) technique. We compare our da…
LC-Circuit Calorimetry
Olaf Bossen, Andreas Schilling
We present a new type of calorimeter in which we couple an unknown heat capacity with the aid of Peltier elements to an electrical circuit. The use of an electrical inductance and…
Experimental tests for macroscopic phase coherence in magnetic-quasiparticle condensates of insulating spin systems
A. Schilling, H. Grundmann, R. Dell'Amore
For most kinds of already known Bose-Einstein condensates experimental evidence for the existence of a macroscopic coherent quantum state has been provided, e.g., from the observat…
Nanoscale Fabrication by Intrinsic Suppression of Proximity-Electron Exposures and General Considerations for Easy & Effective Top-Down Fabrication

We present results of a planar process development based on the combination of electron-beam lithography and dry etching for fabricating high-quality superconducting photosensitive…
Low-temperature differential-thermal analysis to measure variations in entropy
A. Schilling, M. Reibelt
We describe how we can precisely measure variations in the entropy S of small solid samples below room temperature, as a function the temperature T or the external magnetic field H…
