Summary: The cavity axion polariton represents a new frontier in the field of topological matter and light-matter interactions. Our study focuses on short-wavelength axion modes and the axion-axion interaction to realize strong axion-photon coupling and low damping of the axion mode. We discover an unconventional coupling between photon and standing wave axion modes that is in the strong-coupling regime as the number of antinodes is large, and cavity-mediated axion-axion coupling leads to the axion dark mode. Our findings suggest that short-wavelength axion dark modes may have potential applications in quantum manipulation and storage.

Summary: Theoretical study was conducted on the polariton multistability in a solid state optomechanical resonator embedded with a quantum well and a chi ((2)) second order nonlinear medium. It was found that a transition from bistability to tristability occurs in the presence of a strong chi ((2)) nonlinearity. Additionally, the switching between bistability and tristability can be controlled using exciton-cavity and optomechanical coupling.

Summary: Recent experiments have shown that the properties of molecules can be altered inside an optical Fabry-Perot microcavity under collective vibrational strong coupling conditions, but this phenomenon is not yet well understood theoretically. By studying the effect of the cavity environment on the nonlinear optical response of the molecular subsystem, researchers have found that a strong excitation pulse to the lower hybrid light-matter state leads to significantly enhanced molecular nonlinear absorption within the cavity. This polariton-enhanced multiphoton absorption also results in an ultrashort polariton lifetime under strong illumination. The mechanism by which energy is transferred to higher vibrationally excited dark states is expected to be observed experimentally in different molecular systems and cavities.

Summary: In this study, the properties of plasmons in fullerenes C-60, C240, and C-540 were investigated using the GW approximation. It was predicted that a high-frequency plasmon resonance would form in C-240, and in C-540, the intensity of this resonance would become comparable to the intensity of Mie plasmon resonance. This study is the first identification and study of plasmon-polaritons in the excitation spectrum of fullerenes.

Summary: The proposal introduces a method to generate and stabilize various nonlinear modes, such as dark, bright, dark-like, bright-like solitons, and vortices with m = 1 and m = 2, in a nonresonantly pumped exciton-polariton condensate by introducing spatially modulating pumping. Numerical simulations demonstrate that the balance between gain and loss can support the existence and stability of various nonlinear modes beyond just stable dark solitons in this scheme. This proposal may offer a pathway to generate, stabilize, and control nonlinear modes in the nonresonantly pumped exciton-polariton system.

Summary: Within the framework of Maxwell's equation, the study investigates light propagation through a finite heterostructure composed of a pair of bilayers with metamaterial/nonlinear Kerr slabs, with an air defect layer between them. The investigation focuses on modes within the plasmon polariton gap generated by the defect layer. The research demonstrates that by adjusting the layer width and the nonlinearity strength, this simple structure offers a wide range of possibilities for controlling light.

Summary: Coupling molecules to the confined light modes of an optical cavity shows promise for manipulating chemical reactions, but a complete understanding of the effects of strong light-matter coupling on molecular dynamics and reactivity is needed to fully exploit this principle. Despite recent progress in introducing strong coupling effects into quantum chemistry calculations, limitations exist due to challenges associated with accurately describing the cavity.

Summary: This study focuses on a two-DOF nonlinear system under stochastic excitation, examining the influence of random excitation on the stability of nonlinear normal modes (NNMs). Utilizing an analytical-numerical test and the stability definition by Lyapunov, the boundary of stability/instability regions in the system parameter plane is obtained. Additionally, the stability of NNMs under deterministic chaos excitation is also considered.

Summary: Enhanced delocalization is beneficial for absorbing molecules in organic solar cells, and polaritons offer exceptional delocalization that can improve the efficiency of bilayer organic photovoltaics by aiding in exciton delivery to the donor-acceptor interface. The decay of polaritons in bilayer cavities shows an additional pathway through charge transfer, indicating that the charge transfer from the polariton is fast enough to outcompete decay to the ground state.

Summary: Heteroleptic ruthenium (II) complexes were used as sensitizers in organic solar cells to enhance photo-conversion efficiency and stability. The properties of the complexes were tuned by changing substituents, leading to improvements in spectroscopic, photophysical, and electrochemical characteristics. By attaching these complexes to ZnO as an interfacial layer, enhancements in OSC performance were achieved through suppression of degradative reactions and increased stability.

Summary: Thin films of azopolymer-nanoparticles hybrid materials were fabricated with different concentrations of Ag and AgAu nanoparticles, resulting in higher modulations and diffraction efficiency compared to films without nanoparticles. The increase in efficiency was explained by the increase in free volume available for photoisomerization with certain concentrations of nanoparticles. The dependence of diffraction efficiency on concentration was directly related to changes in modulation depth, with maximum efficiency increasing over two times when doped with nanoparticles.

Summary: This study explored the conditions for the direct self-assembly of one-dimensional ZnO nanorod bunches on boron-doped crystalline Si substrates with different conductivities. The results showed differences in the morphology of ZnO nanostructures depending on the Si substrate conductivity used, and XRD patterns indicated preferential formation of ZnO nanorods in the (002) direction. Photoluminescence measurements revealed quantum confined excitons and high emission intensity in the visible range, while spectra showed emission was dominated by the ZnO nanoparticles forming the nanostructures. The study expands the EPD technique applications to form nanorod nanostructures in a single step.

Summary: The dynamics of micrometer-sized magnetic domains in ultrathin ferromagnetic films is slowed down significantly by quenched disorder, making spontaneous elastic tension collapse unobservable at ambient temperature. However, a weak zero-bias ac magnetic field was found to assist curvature-driven collapse, reducing the area of a bubble at a measurable rate, despite negligible effect on average creep motion driven by a comparable dc field. An analytical model quantitatively explains this phenomenon.

Summary: Laser energy absorption on Au nanowire targets under relativistic intensities was measured for the first time, showing a wide variation in absorption values up to 71% of the incident energy. The increase in absorption was found to correlate strongly with larger effective target surface area over a broad range of nanowire parameters explored. These direct absorption measurements provide valuable data for simulations of relativistic laser pulse interactions with nanostructures.
