Paraexciton Excitation in Cu $_{2}$ O under Laguerre--Gaussian Illumination

Nguyen Que Huong, David W. Facemyer

In Cu $_{2}$ O the lowest yellow exciton, the $Γ_{2}^{+}$ paraexciton, is optically inaccessible in conventional spectroscopy because transitions to this state are forbidden in both electr…

Bernal Stacking and Symmetry-Inequivalent Antiferromagnetism in MSi $_{2}$ N $_{4}$ Heterobilayers

Brandon Pedroza-Rojas, David W. Facemyer, Ariadna SÃ¡nchez-Castillo

Layered MA $_{2}$ Z $_{4}$ compounds, structural relatives of MoS $_{2}$ discovered in 2020, exhibit rich magnetic behavior arising from reduced dimensionality, noncentrosymmetric lattice sy…

Probing nonlocal correlations in magnetic rare-earth clusters

David W. Facemyer, Sergio E. Ulloa

Understanding and quantifying entanglement entropy is crucial to characterize the quantum behaviors that drive phenomena in a variety of systems. Rare-earth spin complexes, with th…
