Published in 2020 at "Journal of High Energy Physics"

DOI: 10.1007/jhep03(2020)141

Abstract: We present a general formula for constructing R-matrices with non-additive spectral parameters associated with a type-I quantum superalgebra. The spectral parameters originate from two one-parameter families of inequivalent finite-dimensional irreducible representations of the quantum superalgebra… read more here.

Published in 2025 at "Applied Sciences"

DOI: 10.3390/app15137618

Abstract: While radiation thermometry is well-developed for laboratory calibrations using high-emissivity sources, the effect of spectral emissivity in real-world conditions, where emissivity ranges from 0 to 1, is usually not considered. Spectral parameters that influence non-contact… read more here.
