Integrating First Principles Calculations and Machine Learning to Study the ReNiO2/Ti3C2 Heterojunctions for Sodium Ion Batteries

Advanced Physics Research, EarlyView.
First‐principles calculations demonstrate that the Re1‐xSrxNiO2/Ti3C2 heterostructure exhibits metallic characteristics, with concurrent enhancement in both electronic conductivity and ionic mobility. Machine learning analysis further reveals that strain, lattice parameters and Sr doping concentration critically influence the conductivity.

Interplay Between Spin‐Triplet Pairing and Ferromagnetism in Uranium Ditelluride

Nano Select, EarlyView.
This study investigates how spin triplet superconductivity and ferromagnetism interact in uranium ditelluride (UTe2). It shows that magnetic fluctuations strongly influence the superconducting behavior. The results suggest that ferromagnetic tendencies can contribute to the stabilization of spin triplet pairing. These findings provide new insights into

DC‐Driven Fractional Flux Quanta in Two‐Band Superconductors

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The dc‐driven distancing of fractional flux quanta is theoretically analyzed for a dual‐band superconductor with a periodic pinning potential. The analysis is based on the dynamical equation of motion for a single composite vortex. The model neglects the phase difference between the condensates and may be applicable to two‐band superconductors with ...

Quantum Depletion of Superconductivity in 3D Diamond Nanowires

Advanced Quantum Technologies, EarlyView.
Heavily boron‐doped polycrystalline diamond nanowires demonstrate an exotic resistive state that alters the trend of the superconducting transition. This reentrant resistive state manifests itself as a peak in the current dependence of voltage and a negative magnetoresistance peak. This suggests that cross‐sectional grain boundaries can promote quantum‐

Beyond Kagome: p$p$‐Bands in Kagome Metals

Advanced Quantum Technologies, EarlyView.
Recent studies on quantum materials where transition‐metal atoms give rise to d$d$‐bands typical of kagome metals are reviewed. Using examples from several material families – AV3Sb5${\rm AV}_3{\rm Sb}_5$, FeGe, RV6Sn6${\rm RV}_6{\rm Sn}_6$, and LaRu3Si2${\rm LaRu}_3{\rm Si}_2$ – it is argued that p$p$‐bands contributed by elements beyond the kagome ...

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

Small, EarlyView.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.

Robust Spectral Anomaly Detection in EELS Spectral Images via 3D Convolutional Variational Autoencoders

Small, EarlyView.
Automated anomaly detection is demonstrated for electron energy‐loss spectrum imaging in an atomic‐resolution scanning transmission electron microscope using an unsupervised learning approach. A 3D convolutional variational autoencoder is introduced and tested on the iron L‐edge spectra taken from a single‐crystal BiFeO3 sample.
