Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

Advanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

The Part and the Whole: Field‐Dependent THz‐EPR Spectroscopy Probes Lattice‐Dependent Electronic Structure in Iron(II) Spin Crossover

Angewandte Chemie International Edition, EarlyView.
THz‐EPR spectroscopy provides direct access to the low‐lying electronic structure and spin–phonon coupling in iron(II) spin crossover (SCO) complexes. Quantification of the high‐spin fraction (γHS$\gamma _{\text{HS}}$) and subtle shifts in magnetic transitions reveal the influence of the surrounding lattice and enable discrimination between microscopic

Thermoelectric Response and Field‐Induced Figure of Merit in Fluorine–Doped Carbon Nanotube Using the Lorenz Number

Advanced Physics Research, EarlyView.
Thermoelectric conductivity decreases nonlinearly with increasing temperature for all investigated band‐gap values. Higher energy splitting yields lower conductivity, while smaller gaps maintain superior carrier transport. Peak response occurs at low temperature, followed by gradual saturation at elevated temperatures.

Ab‐Initio Study of Structural, Magnetic, Optoelectronic and Thermophysical Properties of Heusler Compound HoPdBi

Advanced Physics Research, EarlyView.
The top panel shows the electronic band structure, which illustrates how the electronic energy varies with momentum along different high‐symmetry directions within the first Brillouin zone. Band structure determines the electronic character of a crystalline solid.
