First direct search for light dark matter interactions in a transition-edge sensor
Christina Schwemmbauer, Guy Daniel Hadas, Yonit Hochberg +9
We propose the use of transition-edge sensor (TES) single-photon detectors as a simultaneous target and sensor for direct dark matter searches, and report results from the first se…
Any Light Particle Searches with ALPS II: first science results
Daniel C. Brotherton, Zachary R. Bush, Sandy Croatto +37
The light-shining-through-a-wall experiment ALPS II at DESY in Hamburg searched for axions and similar lightweight particles in its first science campaign from February to May 2024…
Characterization of a Two-Channel Optical and Near-infrared Transition Edge Sensor System for Rare-Event Searches
Manuel Meyer, Katharina-Sophie Isleif, Friederike Januschek +5
Transition edge sensors (TESs) are superconducting energy-resolving microcalorimeters that have demonstrated low background rates as well as quantum efficiencies close to unity for…
Binary Classification of Light and Dark Time Traces of a Transition Edge Sensor Using Convolutional Neural Networks
Elmeri Rivasto, Katharina-Sophie Isleif, Friederike Januschek +5
The Any Light Particle Search II (ALPS II) is a light shining through a wall experiment probing the existence of axions and axion-like particles using a 1064 nm laser source. While…
Quantum Mechanics of an Abrikosov Vortex in Nanofabricated Pinning Potential
Elmeri O. Rivasto
A superconducting device is proposed for experimentally investigating whether an Abrikosov vortex can be modeled as a quantum mechanical quasiparticle. The design process of a type…
A New Experimental Method for Determining the Pinning Energy of an Abrikosov Vortex
Elmeri O. Rivasto
We demonstrate a novel method of experimentally addressing the pinning energy of an Abrikosov vortex in high-temperature superconducting thin films. The method is based on our prev…
