Summary: A new scheme has been proposed to calculate electronic couplings for photoinduced charge transfer and excitation energy transfer, which involves constructing locally excited and charge-transfer states by maximizing the localization of particle and hole densities. This method is efficient and applicable to systems with multiple charge or excitation centers, with demonstrated validity in applications to various molecules. Results show that the environment can significantly impact electronic couplings and enhance long-range charge transfer.

Summary: This study presents an automated method for fabricating organic films, which allows control of nearest-neighbor interactions by controlling the ratio of surface to bulk sites and the extension of domain edges. The method enables the production of films with defined morphology and establishes a model for predicting the range of energy levels.

Summary: This article investigates the dynamics of an equilaterally shaped electronic excitation-transfer (EET) trimer with distance-dependent intermonomer excitation-transfer couplings. It is found that symmetric and antisymmetric superpositions of two single-monomer excitations exhibit different interferences in the EET to the third monomer. The shape distortion of the triangular framework affects the coherent EET and activates excitation transfer in the antisymmetric initial state. The study also reveals the significance of Jahn-Teller-active framework distortions in breaking the degeneracy of the trimer's single-exciton states.

Summary: The optical properties of single-layer and multi-fold nanoporous gold leaf (NPGL) metamaterials exhibit highly unusual transmission spectra with two distinct peaks. This phenomenon is explained by the presence of a surface plasmon absorption band on top of a broader transmission band, which is characteristic of both homogeneous solid and inhomogeneous diluted Au films. Additionally, the transmission spectra of NPGL metamaterials can be manipulated by external dielectric environments such as water and applied voltage in an electrochemical cell, suggesting potential applications in controlling spontaneous emission and energy transfer.

Summary: Modifying the way that molecules absorb, transfer, and emit light by coupling them to optical cavities can depend on the strength of the cavity-molecule coupling and the number of coupled molecules. Experimental and numerical studies show the evolution of photoemission from a thin layered J-aggregated molecular material coupled to a Fabry-Perot microcavity. The effect of vibrational modes on polariton assisted emission and the role of Raman scattered photons in populating polariton branches are also explored.

Summary: In this study, greatly enhanced light harvesting and one-photon upconversion were demonstrated in plexcitonic hybrids of chlorophyll molecules strongly coupled to silver nanoparticles. The efficient upconversion was predominantly attributable to the one-photon anti-Stokes process, with photon and phonon absorption processes cooperatively enhanced by plexciton resonance. Additionally, coherent plexcitonic Rabi oscillations and plexciton-enhanced triplet-triplet annihilation were also discussed.

Summary: The destruction of quantum mechanical features by decoherence limits the applicability of quantum technologies. Limited information about quantum features in basis-dependent observations necessitates the use of basis-independent quantities for better understanding. Research shows that even when quantum coherence survives in both localized and eigenstate bases at steady state, state purity may not necessarily reflect the persistence of quantum features.

Summary: This study analyzes charge-transfer plasmons (CTP) in complexes of metal nanoparticles bridged by conductive molecular linkers using a statistic approach. It is found that the frequency distribution of CTP in the generated nanoparticle complexes is very inhomogeneous, with narrow and broad peaks corresponding to different types of plasmon oscillations. The study also proposes modifications to calculate the CTP energy absorption in an external electromagnetic field and demonstrates wide and monotonic absorption in the IR region for systems containing a large number of bridged nanoparticles.

Summary: In this study, the heat flux in a solid-liquid interfacial region is obtained in a three-dimensional space at a subatomic spatial resolution based on classical molecular dynamics. The directional qualities of the heat flux are significantly dependent on the subatomic stresses in the structures of condensed phase systems. The properties of stress and energy flux at the subatomic scale are comprehensively investigated to determine the origin of the thermal transport mechanism at the solid-liquid interface.
