Quantum coherences are the primary signatures of nonadiabatic dynamics in biological complexes, yet their unambiguous detection remains a challenge. Conventional time-resolved spectroscopies rely on temporal beating patterns that are inherently convoluted with population-relaxation dynamics and instrumental artifacts,...

Entangled photons offer quantum correlations with no classical analogue. In entangled pair two-photon absorption (ETPA), absorption rate is predicted to scale linearly rather than quadratically with photon flux, promising molecular excitation at fluxes far below the classical threshold. Reported ETPA cross sections nev...

Charge utilization in photocatalytic CO2 reduction in covalent organic frameworks (COFs) depends not only on generating long-lived charges but on directing them efficiently to catalytic sites. This review connects ultrafast photophysics with interfacial catalysis by examining charge generation, separation, transport, l...
