We introduce an alternative experimental probe, capturing microwave radiation across all three regimes, using a two-dimensional array of superconductor-semiconductor hybrid Josephson junctions as a model system. Our approach allows  calibration of the sample’s circuit parameters and provides isolation from measurement back-action effects. We measure the radiation temperature of the anomalous metal and find that it is hotter than both the quantum-critical and insulating regimes. We further show that the anomalous metallic regime is more susceptible to additional heating than other regimes, explaining its emergence in otherwise thermalized systems. Turning to the quantum-critical regime, we discover nonlinear scaling of radiative noise with applied bias, consistent with theoretical predictions of universal nonequilibrium behavior at quantum-critical points."}],"ddc":["530"],"department":[{"_id":"GradSch"},{"_id":"AnHi"},{"_id":"GeKa"}],"citation":{"ama":"Léonard KW, Bubis A, Mikalsen M, et al.

This process operates on multiple timescales, with the final radiative step consisting of spontaneous emission, which can be modeled within the framework of quasiequilibrium fluctuational electrodynamics. Scintillation can therefore be controlled and enhanced via nanophotonic effects, which has been proposed and experimentally demonstrated. Such designs have thus far obeyed Lorentz reciprocity, meaning there is a direct equivalence between scintillation emission and absorption by the scintillator. However, scintillators that do not obey Lorentz reciprocity have not been explored, even though they represent an alternative platform for probing emission, which is both nonequilibrium and nonreciprocal in nature. In this work, we propose to harness nonreciprocity to achieve directional control of scintillation emission, granting an additional degree of control over scintillation. Such directionality of light output is useful in improving collection efficiencies along the directions where detectors are located. We present the design of a nonreciprocal scintillator using a one-dimensional magnetophotonic crystal in the Voigt configuration. Our work demonstrates the potential of controlling nonequilibrium such as scintillation by breaking reciprocity and expands the space of nanophotonic design for achieving such control.","lang":"eng"}],"type":"journal_article","volume":22,"date_updated":"2026-04-27T10:38:50Z","publication":"Physical Review Applied","quality_controlled":"1","month":"11","arxiv":1,"publication_status":"published","oa":1,"day":"22","_id":"21560","intvolume":"        22","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2409.17002","open_access":"1"}],"year":"2024","date_created":"2026-03-30T12:22:47Z","extern":"1","article_processing_charge":"No","publication_identifier":{"issn":["2331-7019"]},"issue":"5","scopus_import":"1"},{"oa_version":"Preprint","doi":"10.1103/physrevapplied.17.054031","author":[{"full_name":"Li, Vyacheslav","first_name":"Vyacheslav","id":"3A4FAA92-F248-11E8-B48F-1D18A9856A87","last_name":"Li"},{"id":"2E054C4C-F248-11E8-B48F-1D18A9856A87","last_name":"Diorico","orcid":"0000-0002-4947-8924","first_name":"Fritz R","full_name":"Diorico, Fritz R"},{"first_name":"Onur","full_name":"Hosten, Onur","orcid":"0000-0002-2031-204X","id":"4C02D85E-F248-11E8-B48F-1D18A9856A87","last_name":"Hosten"}],"citation":{"ieee":"V.

We present a frequency-offset locking method for lasers based on beat-frequency discrimination utilizing hybrid electronic LC filters. The method is specifically designed for decoupling the tightness of the lock from the broadness of its capture range. The presented demonstration locks two free-running diode lasers at 780 nm with a 5.5-GHz offset. It displays an offset frequency instability below 55 Hz for time scales in excess of 1000 s and a minimum of 12 Hz at 10-s averaging. The performance is complemented with a 190-MHz lock-capture range, a tuning range of up to 1 GHz, and a frequency ramp agility of 200kHz/μs."}],"date_updated":"2026-07-08T08:50:57Z","volume":17,"month":"05","quality_controlled":"1","arxiv":1,"publication":"Physical Review Applied","acknowledgement":"This work was supported by IST Austria.
