Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

open access: yesAngewandte Chemie, EarlyView.
Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

open access: yesAdvanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Inverse Design of Electromagnetic‐Induced Transparency Metasurface Using Conditional Generative Adversarial Network

open access: yesAdvanced Intelligent Systems, EarlyView.
This work develops a CGAN‐based metasurface inverse design method. It adopts an integrated workflow of pixel‐based graphical modeling, simulation, and GAF transform for automatic, batch metasurface dataset construction. With a U‐Net architecture, the CGAN generates high‐resolution, high‐fidelity metasurface structures. EIT verification achieves over 90%
