Abstract
We investigate the information-theoretic properties of Floquet states in an irradiated 8-Pmmn borophene heterostructure. The system consists of a pristine borophene sheet in which a linearly polarized laser field is applied only within a finite central region, generating photonassisted electronic states described within the Floquet formalism. Analytical spinor solutions are obtained for the irradiated and non-irradiated regions, allowing the calculation of Shannon entropies and entropic density distributions in both coordinate and momentum spaces. The results show that increasing the laser frequency and field amplitude enhances the momentum-space entropy and significantly modifies the information distribution of the electronic states. The total entropy always satisfies the Beckner-Bialynicki-Birula-Mycielski uncertainty relation, confirming the consistency of the information-theoretic description. Furthermore, the entropic density reveals the emergence of localized information patterns associated with Floquet sidebands, demonstrating that external irradiation provides an effective mechanism for controlling quantum-information localization in anisotropic borophene systems.
