Unveiling non-Hermitian band structures with non-Bloch supercells
Abstract Real-valued band structures underpin the analysis of periodic Hermitian systems and are well established experimentally. By contrast, non-Hermitian systems feature complex band structures, in which energy and momentum acquire imaginary parts, enabling phenomena that defy conventional Bloch theory. Mapping these complex bands—relating complex momentum to complex energy—and identifying their associated eigenstates is essential yet remains challenging.

Stabilization and destabilization of multimode solitons in nonlinear degenerate multi-pass cavities
Abstract Optical solitons in multimode nonlinear optical systems offer a unique platform for exploring the interplay of nonlinearity, dispersion, and spatial mode coupling, offering insights into complex nonlinear wave phenomena. Multi-pass cavities (MPCs) incorporating nonlinear Kerr media serve as prototypical systems, enabling high-efficiency supercontinuum generation and pulse compression.
Thermal Force Imaging of Hot Electrons in Operando Nanodevices
Abstract The relentless pursuit of smaller, faster nanoelectronics concentrates intense heat at nanometer scales, threatening performance and reliability. Yet directly mapping this heat from nonequilibrium hot electrons has remained elusive. Here we introduce the non-contact force technique that directly images hot-electron temperature distributions in operando devices.

Experimental probe of point gap topology from non-Hermitian Fermi-arcs - Communications Physics
Abstract The gap in spectra of a physical system is fundamental in physics, while gap topology further restricts possible occurrent gaps of topological boundary states. The emergence of non-Hermiticity unveils a unique gap type known as the point gap, which forecasts the wavefunction localization, known as the non-Hermitian skin effect.
Simulation of Time-Sequence Operation Considering DC Utilization Hours of New Energy Base in Desert and Gobi Area
1. Introduction To expedite the development of a clean, low-carbon, safe, and efficient energy system, China has prioritized the construction of extensive new energy bases in deserts, the Gobi, and wastelands [1]. Nonetheless, the variability of new energy output in these areas, particularly its seasonal characteristics, often exacerbates the peak load pressures on thermal power units and limits the full utilization of the transmission capacity within new energy corridors.
Synergistic Ag/g-C3N4 H2O2 System for Photocatalytic Degradation of Azo Dyes
1. Introduction In recent years, rapid industrialization and population growth have led to an ever-increasing exploitation of natural resources, causing environmental pollution to become a progressively escalating global challenge [1,2,3], where water pollution is particularly serious [4,5,6]. Industrial wastewater contains various toxic substances, among which dyes are particularly hazardous toxic wastes.
Non-Bloch theory for spatiotemporal photonic crystals assisted by continuum effective medium
As one indispensable type of nonreciprocal mechanism, a system with temporal modulations is intrinsically open in the physical sense and inevitably non-Hermitian, but the space and time degrees of freedom are nonseparable in a large variety of circumstances, which restrains the application of the non-Bloch band theory.

Abstract As the counterpart of Hermitian nodal structures, the geometry formed by exceptional points (EPs), such as exceptional lines (ELs), entails intriguing spectral topology. We report the experimental realization of order-3 exceptional lines (EL3) that are entirely embedded in order-2 exceptional surfaces (ES2) in a three-dimensional periodic synthetic momentum space.

Boron‐Doped Electrolytes as Interfacial Modifiers for High‐Rate Stable Lithium Metal Batteries
Abstract In this article BF3 etching is applied to fabricate basic SEI (B-SEI) layers enriched with LiF and LixBFy. Artificial solid electrolyte interface (A-SEI) with a “stromatolite” structure is formed on top of the B-SEI growth during the charge-discharge cycles. The structure of A-SEI is characterized laterally and longitudinally by distribution of TEM elements and depth-profile XPS, providing evidence for the elucidation of a new lattice-tuning Li+ “layered” deposition-type SEI structure.

A Multi-Hop Graph Neural Network for Event Detection via a Stacked Module and a Feedback Network
Abstract : Event detection is an important subtask of information extraction, aiming to identify triggers and recognize event types in text. Previous state-of-the-art studies using graph neural networks (GNNs) are mainly applied to obtain long distance features of text and have achieved impressive performance. However, these methods face the issues of over-smoothing and semantic feature destruction, when containing multiple GNN layers.

Transformation optics approach to mesoscopic plasmonics
Abstract Macroscopic continuous-medium descriptions fail to capture the electromagnetic response of mesoscopic-scale objects due to the quantum nature of electrons. Such deviations from classical treatments can be alleviated by introducing surface parameters known as the Feibelman d parameters in the boundary conditions of electric and magnetic fields, which has been experimentally demonstrated.

\ifmmode \check{C}\else \v{C}\fi{}erenkov radiation in vacuum from a superluminal grating
Abstract Nothing can physically travel faster than light in vacuum. There are several ways proposed to bypass the light barrier and produce Čerenkov radiation (ČR) in vacuum. In this paper, we theoretically predict ČR in vacuum from a spatiotemporally modulated boundary. We consider the modulation of traveling wave type and apply a uniform electrostatic field on the boundary to generate electric dipoles. Since the induced dipoles stick to the interface, they travel at the modulation speed.

Suprachoroidal gene transfer with nonviral nanoparticles
Abstract Subretinal injections of viral vectors provide great benefits but have limited cargo capacity; they induce innate and adaptive immune responses, which may cause damage and preclude repeated injections; and they pose administration risks. As a new biotechnology, suprachoroidal injections of biodegradable nanoparticles (NPs) containing a reporter plasmid induce reporter expression in rat photoreceptors and RPE throughout the entire eye and maintain expression for at least 8 months.

Exceptional points and their coalescence of $\mathcal{PT}$-symmetric interface states in photonic crystals
Abstract The existence of surface electromagnetic waves in the dielectric-metal interface is due to the sign change of real parts of permittivity across the interface. In this work, we demonstrate that the interface constructed by two semi-infinite photonic crystals with different signs of the imaginary parts of permittivity also supports surface electromagnetic eigenmodes with real eigenfrequencies, protected by PT symmetry of the loss-gain interface.

Due to the complementary properties of different features, multiple feature fusion has a large potential for hyperspectral imagery classification. At the meantime, hashing is promising in representing a high-dimensional float-type feature with extremely low bit binary codes while maintaining the performance. In this paper, we study the possibility of using hashing to fuse multiple features for hyperspectral imagery classification.
