Physicists are always riveted in predicting how a physical system behaves as a function of time. We begin this review article by understanding various formalisms to study the dynamics of the systems. The once-accepted belief that the Hamiltonian had to be Hermitian to ensure real eigenvalues got crashed down by parity-time (PT) symmetry where the Hamiltonian is no longer Hermitian. Thus, the idea of PT symmetry demonstrated that Hamiltonian's Hermicity is not necessary but sufficient to ensure the real eigenvalues. In this review article, we clearly describe the fundamental principle of PT symmetry, its significant attributes and its evolution in various fields of Physics, especially in Optics. In recent years, an artificial material called metamaterial has gained phenomenal momentum due to its unusual electromagnetic properties. These subwavelength-scale artificial electromagnetic materials can provide a variety of mediums for exploring non-Hermitian phenomena. Thus, the implementation of PT symmetry in metamaterial opened up an extended range of unusual phenomena in light-matter interaction. This paper addresses recent developments in PT metamaterials and highlights a few of its applications. Graphical Abstract
Ceres Holographics, in collaboration with Eastman Chemical, has unveiled the industry’s first fully integrated windshield featuring multiple holographic optical elements (HOEs) inside a single laminate construct. This innovation, being showcased at Car.HMI Europe, uses Ceres’ HoloFlekt® technology to produce films with multiple HOEs that are then seamlessly laminated inside windshield glass using Eastman’s proprietary lamination techniques.

Dogs and cats have exceptionally developed sensory systems and abilities to recognize human signals and emotional states. It makes them invaluable in roles such as working dogs and therapy
animals in human society. Understanding each other’s emotional state is essential to working with them effectively. However, the low accuracy of human emotional estimation in dogs and cats is a significant issue. Due to individual differences and cognitive biases affecting human subjective assessments, automatic emotional estimation is crucial. To address this issue, there is a demand for automated emotional estimation technology. This paper provides an overview of emotional research in dogs and cats, their senses, and their roles in interaction with humans. In addition, we described automated emotional estimation technology using image/video and electrocardiography as a complement to human ability for emotional recognition of dogs and cats, and its applications for implementation. Practical implementation of automated emotional estimation technology should be adaptable to different breeds, individuals, and environmental conditions. Improving this technology has the potential to contribute to various fields, including pet welfare enhancement, veterinary care, ethology, and support for humans with dogs or cats. ! https://www.tandfonline.com/cms/asset/2207e63b-7342-482b-b6c0-26b5b0a48759/tadr_a_2358439_f0001_ob.jpg
Wang, Y., Zhong, L., Lau, K.Y. et al. Precise mode control of laser-written waveguides for broadband, low-dispersion 3D integrated optics. Light Sci Appl13, 130 (2024). https://doi.org/10.1038/s41377-024-01473-7
"Three-dimensional (3D) glass chips are promising waveguide platforms for building hybrid 3D photonic circuits due to their 3D topological capabilities, large transparent windows, and low coupling dispersion. At present, the key challenge in scaling down a benchtop optical system to a glass chip is the lack of precise methods for controlling the mode field and optical coupling of 3D waveguide circuits. Here, we propose an overlap-controlled multi-scan (OCMS) method based on laser-direct lithography that allows customizing the refractive index profile of 3D waveguides with high spatial precision in a variety of glasses. On the basis of this method, we achieve variable mode-field distribution, robust and broadband coupling, and thereby demonstrate dispersionless LP21-mode conversion of supercontinuum pulses with the largest deviation of <0.1 dB in coupling ratios on 210 nm broadband. This approach provides a route to achieve ultra-broadband and low-dispersion coupling in 3D photonic circuits, with overwhelming advantages over conventional planar waveguide-optic platforms for on-chip transmission and manipulation of ultrashort laser pulses and broadband supercontinuum."
Wavelength-tunable structural colors using stimuli-responsive materials, such as chiral liquid crystals (CLCs), have attracted increasing attention owing to their high functionality in various tunable photonic applications. Ideally, on-demand omnidirectional wavelength control is highly desirable from the perspective of wavelength-tuning freedom. However, despite numerous previous research efforts on tunable CLC structural colors, only mono-directional wavelength tuning toward shorter wavelengths has been employed in most studies to date. In this study, we report the ideally desired omnidirectional wavelength control toward longer and shorter wavelengths with significantly improved tunability over a broadband wavelength range. By using areal expanding and contractive strain control of dielectric elastomer actuators (DEAs) with chiral liquid crystal elastomers (CLCEs), simultaneous and omnidirectional structural color-tuning control was achieved. This breakthrough in omnidirectional wavelength control enhances the achievable tuning freedom and versatility, making it applicable to a broad range of high-functional photonic applications. On-demand color control, enabling simultaneous and omni-directional wavelength tuning towards both shorter (blue-shift) and longer (red-shift) wavelengths, is reported using stretchable chiral liquid crystal elastomers.
Over the past decade, the use of the internet has undergone a massive evolution across the globe. Today, the metaverse can be viewed as one of the driving forces that is aiding the transformation of various industries such as entertainment, technology, gaming, etc. Due to the metaverse’s increasing popularity and usage, protecting intellectual property rights (“IP”) has come to the forefront and will play a crucial role in safeguarding ownership rights in the metaverse including the creation of digital avatars and use of virtual goods.
Usage of IP in the metaverse ushers its own set of multifold challenges and opportunities. In this article series of IP in the metaverse, we aim to analyze essential IP that needs to be safeguarded in the metaverse.
GitHub announced that it will make generative AI models more accessible to developers by tightly integrating with existing tools and features. This new capability, known as GitHub Models, allows developers to explore various models within the GitHub web interface. They can also test and compare different models without leaving their current environment."
