Non-uniqueness of the amplitude reconstruction in the inverse scattering problem and a refinement of Hoehler's resonance clustering
Reaction-amplitude reconstruction in the inverse scattering problem is limited by the bilinear form of all reaction observables.Wigner-Function Fingerprints of Collective Excitations in Mirror-Terminated Waveguide QED
We investigate the emission profiles of singly excited collective states and propose a matched-mode witnessing protocol in a mirror-terminated waveguide quantum electrodynamics system.Time-invariant negativity and persistent bound entanglement in a cyclic two-qutrit family
We study the entanglement dynamics of two qutrits under collective dephasing for a family of states obtained by mixing a maximally entangled state that lives in the decoherence-free subspace with…On Random Purifications of Isometries and Channels
Acorn tricks turn weak quantum resources into stronger "randomized" ones.Spectral Quantum Memory for Implicit Neural Representations
Implicit neural representations (INRs) model signals as continuous functions from coordinates to values, but their performance depends strongly on how spectral capacity is allocated.Impedance-controlled Laser Dynamics in Near-Zero Index Media
Near-zero-index (NZI) media have been explored for controlling spontaneous emission, but their impact on stimulated emission and lasing properties remains unexplored within their different classes…Adaptive Self-Optimization of Polarization Efficiency for Low-Power NV Center Thermometers Based on PAS-Q
Nitrogen-vacancy (NV) centers in diamond have attracted considerable attention for micro- and nanoscale thermometry owing to their high precision and spatial resolution.SCANO: Restoring Boundary-Condition Completeness in Sampled Meshes with a Sliced-Cross-Attention Neural Operator for 3D Thermal Fields
Training neural operators on million-cell meshes can exceed GPU memory limits.Probing the Faint Outskirts of Star-Forming Galaxies with 1<z<9 Using Stacked Images

We revisit the classical spectral problem for the Laplace-Beltrami and Laplace-Bochner operators on complex Grassmannians.Cooperative Suppression of Two-Particle Excitation by Kerr Nonlinearity and Cavity Loss ion a Driven Holstein-Tavis-Cumming System
We apply the numerically accurate multiple Davydov Ansatz (multi-$\rm D_2$) method to investigate the nonequilibrium dynamics of an open molecular cavity system using an extended driven-dissipative…Breakdown of Linearized Dispersion in Waveguide QED
Exploring interactions between quantum emitters and guided photons, waveguide quantum electrodynamics (wQED) offers a versatile platform for quantum simulation and quantum interconnect.Feature-Based and Deep Learning Methods for Astronomical Light Curve Classification
We compare feature-based machine learning and end-to-end deep learning for variable star classification using the Zwicky Transient Facility (ZTF) StarEmbed dataset, which contains about 40,000…On flow unsteadiness in strongly separated high-speed ramp flows using kinetic and data-driven methods
The gas dynamics of high speed flows over several compression-expansion ramp geometries with large separation regions were investigated using a particle kinetic approach and data driven methods.Quantum Simulation of Electronic Structure using Quantum Density Functional Theory on a Programmable Integrated Photonic Circuit
Quantum simulations of molecular electronic structure hold the potential for computational advantage but are inherently limited by the linear scaling of qubit requirements with respect to system size.Surrogate Models for Stochastic Al-Cu Phase-Field Solidification
Phase-field models resolve microstructural evolution during rapid alloy solidification, but their computational cost limits long trajectories, stochastic ensembles, and studies across process…Precise and accurate nuclear electric quadrupole moment of $^{223}$Ra from molecular spectroscopy
Nuclear electric quadrupole moments of unstable isotopes are commonly extracted from laser spectroscopy of the atomic hyperfine structure, where the accuracy is limited to the several-percent level…Closed- and open-system characterization of the Yukawa-SYK model in real time
Strongly correlated matter without quasiparticles is central to many-body physics, quantum chaos, and quantum gravity, motivating a considerable effort toward its realization in tabletop experiments.Bayesian optimization enhanced magnetic field gradient detection based on spin-orbit coupled Bose-Einstein condensates
Magnetic field detection is of great significance in modern fields such as medical diagnostics, geological exploration, inertial navigation, and space physics.The TNG50-SKIRT Atlas: Multi-wavelength properties of galaxy discs in the TNG50 simulation
We investigate the wavelength dependence of disc scale lengths in galaxies from the TNG50-SKIRT Atlas (TSA), and assess whether the simulated galaxies reproduce the structural properties and scaling…
