We report on the detection by means of Raman spectroscopy of amorphous beryllium deuteride, BeD 2 , in magnetron sputtered deposits synthesized in two different laboratories and co…
Multiscale analysis of crystal defect formation in rapid solidification of pure aluminium and aluminium-copper alloys
Tatu Pinomaa, Matti Lindroos, Paul Jreidini +6
Rapid solidification leads to unique microstructural features, where a less studied topic is the formation of various crystalline defects, including high dislocation densities, as…
Infrared spectroscopy of radioactive hydrogen chloride HCl
Santeri Larnimaa, Markku Vainio, Ville Ulvila
We present the first report of optical absorption spectroscopy of HCl, a radioactive isotopologue of hydrogen chloride. We used Fourier-transform infrared spectroscopy to…
Quantum guessing games with posterior information
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
Quantum guessing games form a versatile framework for studying different tasks of information processing. A quantum guessing game with posterior information uses quantum systems to…
Charge dynamics in quantum-circuit refrigeration: thermalization and microwave gain
