The One‐Dimensional Coulomb Hamiltonian: Properties of Its Birman–Schwinger Operator

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11813-11822, August 2025.
ABSTRACT The objective of the present paper is to study in detail the properties of the Birman–Schwinger operator for a self‐adjoint realization of the one‐dimensional Hamiltonian with the Coulomb potential, both when the Hamiltonian is defined only on ℝ+$$ {\mathbb{R}}_{+} $$ and when it is defined on the whole real line.

Quantum Depletion of Superconductivity in 3D Diamond Nanowires

Advanced Quantum Technologies, Volume 8, Issue 8, August 2025.
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‐

Testing for the Important Components of Predictive Variance

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 18, Issue 4, August 2025.
ABSTRACT We give a decomposition of the predictive variance based on the law of total variance by making the response variable dependent on a finite dimensional discrete random variable representing our modeling assumptions. Then, we test which terms in this decomposition are small enough to ignore.

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

Small, Volume 21, Issue 33, August 21, 2025.
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.
