Summary: This study focuses on the thermalization dynamics of one-dimensional diatomic lattices, comparing the behavior of the Fermi-Pasta-Ulam-Tsingou (FPUT)-beta and the Toda models. It is found that the final thermalization time and metastable state of the two models differ, but both follow the same scaling law in the near-integrable region. Additionally, comparisons of the thermalization behavior under various initial conditions are briefly summarized.

Summary: Tunable metasurfaces can change optical properties of incident light with fast switching speed and small pixel size, enabling various applications. However, implementing a two-dimensional metasurface pixel array that can be individually addressed in the optical frequency regime remains challenging.

Summary: We propose and study a new phase of two-dimensional shifted charge density waves (CDW) that is composed of weakly coupled one-dimensional CDW wires with varying phases. We demonstrate that the fully gapped bulk CDW possesses topological properties, characterized by a non-zero Chern number, which leads to the presence of edge modes within the bulk energy gap. Remarkably, these edge modes exhibit spectral pseudoflow along the edge, analogous to the chiral edge modes of Chern insulators in momentum space. Additionally, we show that the CDW edge modes remain stable even in the presence of interwire coupling. These predictions can be experimentally tested in quasi-one-dimensional CDW compounds such as Ta2Se8I.

Summary: This paper proposes to enhance the anti-laser damage performance of 1D SWGs by reducing the peak electric field at the grating ridges, deriving equations for solving the field intensity of dielectric materials based on Maxwell's equations. It discusses the effects of profile shape, structural parameters, and refractive index on the near-field distribution and concludes that the near-field distribution greatly depends on the laser polarization direction.

Summary: The authors present a generalizable synthesis strategy to fabricate a library of one-dimensional inorganic perovskite nanomeshes via pyrolysis of metal salt-polymer fibers. Among the evaluated pemvskite nanomeshes, La0.5Ba0.5Co0.8Ni0.2O3 shows the most remarkable performance for the oxygen evolution reaction (OER). Introduction of additional metals endows more flexible electronic structures to realize electron transfer in 1D pemvskite nanomeshes. This work demonstrates a scalable and retrosynthetic route to easily synthesize inorganic pemvskite nanomaterials with tunable compositions.

Summary: We report the localization of an acoustic wave at the interface between two one-dimensional hyperuniform materials of different geometrical representations, which suppress acoustic scattering in the long wavelength regime and possess a wide band gap. These materials are made of an air-filled acoustic waveguide with rigid diaphragms acting as scatterers, offering promising applications in wave control devices with wide band gap and emergence of edge modes.

Summary: An important challenge in contemporary photonics research is the miniaturization of optical components and devices for more compact and energy-efficient mobile platforms. Arrays of subwavelength scatterers, or meta-optics, provide a solution by shaping and manipulating transmitted optical wavefronts. This paper presents the concept of a computational spectrometer that utilizes a high-efficiency double helix meta-optic and computational back end to accurately reconstruct optical spectra.

Summary: In this study, lattice dynamics in photoexcited WSe2/WS2 heterostructures were directly visualized using femtosecond electron diffraction. It was found that both WSe2 and WS2 were heated simultaneously on a picosecond timescale, which cannot be explained by phonon transport across the interface. First-principles calculations revealed a fast channel involving layer-hybridized electronic states, enabling phonon-assisted interlayer transfer of photoexcited electrons. Phonons were emitted in both layers on the femtosecond timescale via this channel, consistent with the simultaneous lattice heating observed experimentally. Strong electron-phonon coupling via layer-hybridized electronic states was identified as a novel route for controlling energy transport across atomic junctions.

Summary: Photonic integrated circuits (PICs) can greatly enhance the capabilities of optical information science and engineering. We propose using wide-bandgap non-volatile phase-change materials (PCMs) to create rewriteable PICs. A nanosecond pulsed laser can be used to write a PCM-based PIC without removing any material. The entire circuit can be erased by heating and a new circuit can be rewritten. Our proposed platform enables low-cost manufacturing and has significant implications for rapid prototyping of PICs, design validation, and photonic education.

Summary: Ultrathin flat meta-optics have shown promise for holography, but most reported holograms only modulate phase and neglect amplitude. Complex phase modulation typically requires polarization-sensitive meta atoms or complex scatterers. This study demonstrates polarization-independent holography with both amplitude and phase modulation using dielectric meta-optics. The researchers also show that meta-optical holography can be achieved using partially incoherent light from an LED, reducing alignment complexity.

In this study, a programmable photonic cavity array made of silicon material is demonstrated, which can control the temperature of each cavity independently, implement tight-binding Hamiltonians in the telecom regime, and reduce the thermal crosstalk between neighboring sites.

Summary: Tunablenanophotonic resonators are crucial for material-integrated photonic systems and solid-state cavity quantumelectrodynamic experiments. Matching the cavity resonance with the material optical transition is important for enhancing light-matter interaction, which leads to various phenomena with implications in quantum optics and optoelectronics. However, precise control of the resonant wavelength of nanofabricated optical cavities is challenging, requiring postfabrication dynamical tuning, especially in cryogenic environments. In this study, we achieved large in situ strain tuning of an integrated monolayer WSe2-galliumphosphide cavity device. We successfully tuned an on-substrate cavity with a quality (Q)-factor of approximately 3500 at around 780nm by approximately 5nm without any degradation of the Q-factor at cryogenic temperature. The tunable cavity modes were observed as cavity-enhanced monolayer exciton photoluminescence.
