DOI: 10.1002/adma.202303077

Abstract: The planar spin glass pattern is widely known for its inherent randomness, resulting from the geometrical frustration. As such, developing physical unclonable functions (PUFs)-which operate with device randomness-with planar spin glass patterns can be a… read more here.

recommendations! Published in 2020 at "Annalen der Physik"

DOI: 10.1002/andp.202000022

Abstract: Topological insulators are internally insulating but allow topologically protected surface waves at the boundary. In this work, the photonic analogue of topologically protected surface states in gyro‐electromagnetic metamaterials are discovered. It is analytically and numerically… read more here.
