Physics-Guided Interpretable Machine Learning Framework for Anomalous Transport in Crowded Media with Tunable Flexibility

This paper presents a physics-guided interpretable machine learning framework that combines Brownian Cluster Dynamics simulations with SHAP analysis to quantitatively disentangle the individual and coupled effects of crowding, composition, and tunable bond flexibility on particle transport in crowded media, revealing bond flexibility as a distinct regulator of relaxation in heterogeneous colloidal networks.

Stacking Polarity-Controlled Interlayer Photocarrier Dynamics in MoSe2/MoS2 Heterostructures

This study demonstrates that stacking polarity serves as a global control parameter for interlayer photocarrier dynamics in MoSe2_2/MoS2_2 heterostructures, where engineering the interface termination in 3R stacking enables deterministic tuning of charge-transfer rates and interlayer exciton lifetimes by modulating interfacial wavefunction overlap.

Singular geometry and eigenframe topology in local rank-2 tensor observables

This paper reveals that while symmetric second-rank tensors like the electric-field-gradient appear smooth, their magnitude-ordered principal value representations conceal a global topological effect where continuous transport around degeneracies induces a binary orientation reversal of the eigenframe, a phenomenon demonstrated through strain-controlled first-principles calculations in rutile TiO2, SnO2, and cubic MgO.

The interplay of crystal-field transitions and exchange spin dynamics in a ferrimagnet

Using temperature-dependent THz time-domain spectroscopy, the study reveals a hybridization between Yb-ion crystal-field excitations and Yb-Fe exchange modes in Gd3/2_{3/2}Yb1/2_{1/2}BiFe5_{5}O12_{12} that drives an anomalous redshift of the exchange mode near the magnetization compensation temperature, highlighting the critical role of crystal-field-mediated exchange coupling in shaping low-energy spin dynamics for future THz spintronic applications.

Soft-mode nonlinearities away from ferroelectric phase transition

By combining linear and two-dimensional terahertz spectroscopy on paraelectric SrTiO3_3 with a microscopic model, this study demonstrates that while local-field effects drive the hybrid character of soft optical phonon modes, spontaneous macroscopic polarization is the deterministic factor required to initiate non-perturbative lattice dynamics and soft-mode nonlinearities.

Thermal/epithermal neutron detection via LiO2_{2}-doped fiber bundles: A computational study through GEANT4 simulations

This computational study using GEANT4 simulations demonstrates that fiber bundles composed of Kuraray Y11-200(M) fibers doped with 10 wt.% LiO2_2 are effective for detecting thermal and epithermal neutrons by capturing secondary alpha-triton pairs generated via neutron capture and converting them into detectable optical photons.
