Dark matter searches with a 13 meV threshold superconducting sensor array
Christopher Albert, Lanqing Yuan, Jacob Harris +13
Many well-motivated dark matter models predict meV-scale energy deposits in interactions with terrestrial experiments, but this regime is challenging to probe due to a lack of matu…
Reconfigurable Superconducting Logic for On-Chip Photon Coincidence Detection
Gabriel Le Guay, Matteo Castellani, Reed Foster +5
Scaling photonic quantum-information platforms requires arrays of superconducting nanowire single-photon detectors (SNSPDs) for feedforward control, in which optical operations are…
Fast Real-Axis Eliashberg Calculations: Full-bandwidth solutions beyond the constant density of states approximation
Alejandro Simon, James Shi, Dominik Spath +10
Experimentally relevant signatures of superconductivity require access to real-frequency quantities, such as the spectral functions, optical response, and transport properties, yet…
Ultrafast dynamics and light-induced superconductivity from first principles
Alejandro Simon, James Shi, Eva Kogler +9
Experiments on superconducting materials have unveiled unique emergent properties when they are driven far from equilibrium. However, a quantitative first-principles treatment that…
Fast-Recovery Epitaxial NbN Superconducting Nanowire Single-Photon Detectors with Saturated Efficiency at 1550 nm in Liquid Helium
Francesca Incalza, Matteo Castellani, Dip Joti Paul +5
Achieving both high internal efficiency and fast reset times at elevated temperatures remains challenging due to limited understanding of how film properties govern SNSPD performan…
Modeling electrothermal feedback of superconducting nanowire single photon detectors in SPICE
Hanson Nguyen, Alejandro Simon, Reed Foster +1
Superconducting nanowire single-photon detectors (SNSPDs) exhibit complex switching behaviors due to electrothermal feedback during the detection process. Modeling and understandin…
