Local Sources of Phase Curvature and Rigidity in Finite Quantum Matter
Riccardo Castagna
Finite coherent quantum systems exhibit a nontrivial response to local sources of phase curvature, which cannot be reduced to conventional forces, disorder-induced localization, or…

From Diffraction to Refraction: a coherence-based conceptual framework
Riccardo Castagna, Gautam Singh, Cristiano Riminesi +2
Refraction, traditionally viewed as a geometric event occurring at material interfaces, is now being re-examined through the lens of coherence. Recent studies in optics and photoni…
