Author(s): Andrii Iurov, Liubov Zhemchuzhna, and Tiyhearah Danner-Jackson This paper presents a detailed theoretical investigation of the energy spectrum, band gaps, topological and collective properties, and linear response in $d$-wave altermagnets in the presence of an off-resonance optical dressing field. We consider the altermagnets with both ${d}_{{x}^{2}−{y}^{2}}$ a… [Phys. Rev. B 114, 125411] Published Fri Aug 14, 2026
