Published in 2022 at "Science"

DOI: 10.1126/science.abi9232

Abstract: The fine structure constant α sets the strength of the electromagnetic force. The Standard Model of particle physics provides no explanation for its value, which could potentially vary. The wavelengths of stellar absorption lines depend… read more here.

Published in 2023 at "Sensors"

DOI: 10.3390/s23115171

Abstract: Despite its growing importance in the energy generation and storage industry, the detection of hydrogen in trace concentrations remains challenging, as established optical absorption methods are ineffective in probing homonuclear diatomics. Besides indirect detection approaches… read more here.
