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

Mathematical Methods in the Applied Sciences, EarlyView.
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.

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

A Bilevel Optimal Control Method and Application to the Hybrid Electric Vehicle

Optimal Control Applications and Methods, EarlyView.
Schematic representation of the Macro‐Micro method. ABSTRACT In this article we present a new numerical method based on a bilevel decomposition of optimal control problems. A strong connection between the proposed method and the classical indirect multiple shooting method is shown in the regular case, thanks to a link between the Bellman's value ...
