Summary: The exchange of energy between materials and optical fields results in strong light-matter interactions and the formation of polaritonic states with unique properties. Initially studied mostly by physicists using inorganic materials and cryogenic temperatures, recent research has shown that polaritonic states can be achieved at room temperature even in rapidly fabricated metallic optical cavities, making them accessible to chemists, materials scientists, and biochemists. The emergence of exciting phenomena suggests that polaritonic states have genuine relevance in molecular and material energy landscapes.

Summary: This study resolves the controversy regarding the propagation mechanism of polaritons by conducting molecular dynamics simulations of Rhodamine molecules in a Fabry-Perot cavity. The results indicate that polariton propagation is limited by the cavity lifetime and appears diffusive due to reversible population transfers between polaritonic states.

Summary: Microcrystals with different orientations of thiophene/phenylene co-oligomers (TPCOs) were prepared as Fabry-Perot microresonators using a miniemulsion technique. Strong exciton-photon coupling was demonstrated for BP2T and BP2T-CN microcrystals owing to their active microresonators providing effective photonic mode confinement. The strength of the coupling between excitons and photons is correlated with the refractive index and absorption coefficient originating from the transition dipole moment and oscillator strength, with BP2T-CN achieving a larger value of omega due to its higher absorption coefficient, larger refractive index, and smaller mode volume.

Summary: By exploiting momentum space topology, topological control of 2D perovskite emission in the strong coupling regime via polaritonic bound states in the continuum (BICs) is demonstrated, with observation of polarization singularities and achieving high degree of circular polarization in symmetry-broken structures. Lower polariton modes shifting to low-loss spectral region in strong coupling regime results in strong emission enhancement and large degree of circular polarization.

Summary: In this paper, we achieve strong light-matter coupling between a surface plasmon and two organic emitters, resulting in hybrid materials with bifunctionality properties. The optical properties of the materials are drastically modified between activated and deactivated forms of a photochromic material coupled to a cyanine dye, allowing for a tunable emission system. Light-matter interaction is shown to have the potential for modifying the fluorescence of photochromes without the need for covalent bonding.

Summary: By optimizing the strong coupling between perovskite excitons and quasi-bound states in the continuum, supported by an all-perovskite metagrating with high-quality factor, it is possible to achieve a record high Rabi splitting value. The thickness of the perovskite metasurface and the Q-factor of the QBIC mode play dominant roles in enhancing the strong coupling.

Summary: The study explores the strong coupling between surface plasmons and molecular excitons, where an additional anti-crossing feature may arise at high oscillator strengths, but the physics behind this double anti-crossing feature is still unclear. Extensive transfer matrix simulations reveal different anti-crossing features between surface plasmons and excitonic resonances at different oscillator strengths.

Summary: Manipulating chemistry and material properties using hybrid light-matter states has attracted considerable interest in the past decade. The strong coupling phenomenon occurs in the dark and does not require real photons to induce. Vibrational strong coupling offers exciting possibilities for molecular and material science.

Summary: Fano resonance is a phenomenon where weak interaction between discrete and continuous excited states leads to asymmetric line shapes in the spectra. In the strong-coupling phase, the spectral function of the discrete state splits up and produces destructive interferences or zeros.

Summary: This study reports in situ observations of the growth of silicon nanowires in a transmission electron microscope, revealing the behavior and mechanisms of droplets during the growth process. The results show that crystalline silicon nanowires can be grown on a membrane through the movement and dissolution of the droplet. By investigating the geometric properties of the nanowires, the results are consistent with theoretical predictions.

Summary: This paper describes a CMOS process based on the sol-gel method for temperature compatible (400 degrees C) integrated circuits. The properties of aluminum-doped zinc oxide (AZO) thin films were investigated, and it was found that the electrical resistivity is related to the orientation and aluminum content. This research is of great significance for next-generation flexible, microsystem, and optoelectronic devices.

Summary: The ultrafast scattering dynamics of intersubband polaritons in dispersive cavities embedding GaAs/AlGaAs quantum wells were directly studied using a noncollinear pump-probe geometry with phase-stable midinfrared pulses. Selective excitation of the lower polariton at a frequency of similar to 25 THz and at a finite in-plane momentum k(parallel to) resulted in the emergence of a narrowband maximum in the probe reflectivity at k(parallel to) = 0. A quantum mechanical model identified the underlying microscopic process as stimulated coherent polariton-polariton scattering.

Summary: This study investigates the application of HgTe nanocrystals (NCs) in photodiodes using a SnO2/HgTe/Ag2Te structure. By optimizing the band alignment, the SnO2 layer filters out hole dark current while allowing photogenerated electrons to flow, resulting in enhanced rectifying behavior and high internal efficiency. The study also addresses the challenge of transferring the diode onto readout circuits and demonstrates the reversibility of the diode stack with a partially transparent conducting electrode on the top, maintaining device responsivity. Additionally, the SnO2 layer benefits electron injection and enhances electroluminescence signals.

Summary: The success of GeSn alloys as active materials for infrared lasers has the potential to advance monolithic technology in mainstream silicon photonics. However, in order to operate on a chip, the lasers need to work at room temperature or higher. This study presents a strain engineering approach to induce large tensile strain in GeSn alloy micro-disks with a Sn content of 14 at%, enabling robust multimode laser emission at room temperature.
