Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

Advanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

Dissipative stabilization of maximal entanglement between nonidentical emitters via two-photon excitation

Physical Review Research
Two nonidentical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. In Vivas-Viaña, Martín-Cano, and Sánchez Muñoz [Phys. Rev. Lett.

Cross‐Layer Molecular Design for Coherent Interface Passivation in Rigid and Flexible Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A cross‐layer passivation strategy employing molecularly designed thiazol‐5‐ylmethanamine hydrochloride (TMACl) enables coherent defect regulation at the SnO2/perovskite interface, stabilizes both layers, promotes phase‐pure α‐FAPbI3 formation, and enhances charge extraction, delivering PCEs of 26.44% in rigid and 24.72% in flexible perovskite solar ...

Controlling the spontaneous emission and entanglement of quantum scatterers via modulated reflection of their emitted photons

New Journal of Physics
We propose an experimental setup for manipulating the spontaneous emission (SE) of quantum scatterers, based on a spatial light modulator. We discuss this idea in the case of trapped barium ions as quantum emitters.

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

Advanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...
