Normalized solutions for a nonlinear Dirac equation

open access: yesJournal of Differential Equations
We prove the existence of a normalized, stationary solution $Ψ\colon \mathbb{R}^{3} \to \mathbb{C}^{4}$ with frequency $w > 0$ of the nonlinear Dirac equation. The result covers the case in which the nonlinearity is the gradient of a function of the form \begin{equation*} F(Ψ) = a|(Ψ, γ^{0}Ψ)|^{\fracα{2}} + b|(Ψ, γ^{1}γ^{2} γ^{3} Ψ)|^{\fracα{2 ...

Amorphous, Highly Conductive Pr0.7Ca0.3MnO3 for Area‐Dependent Resistive Switching AlOx Bilayer Devices

open access: yesAdvanced Electronic Materials, Volume 12, Issue 17, 7 September 2026.
High‐conductive amorphous Pr0.7Ca0.3MnO3 (PCMO) is explored as an alternative to polycrystalline PCMO for memristive heterostructures with back‐end‐of‐line compatibility, targeting neuromorphic hardware integration. Structural, electrical, and band alignment analyzes are correlated with the electrical characterization of area‐dependent resistive ...

Quantum Master Equation for Electronic Structure in Open Graphene: Non‐Hermitian Hamiltonians and Types of Dissipative Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 9, September 2026.
Electron transport is studied between carbon atoms in the open graphene, while assuming bands to be collective states of electrons in the presence of lattice atoms. To describe dissipative effects, non‐Hermitian extension of the band Hamiltonian is proposed, which models spontaneous emission or injection.

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

open access: yesAdvanced Physics Research, Volume 5, Issue 9, September 2026.
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.

The general integrable inhomogeneous Dirac–Manakov equations: Darboux-dressing transformation and N-soliton solutions

open access: yesNuclear Physics B
By means of the zero-curvature equation and two sets of Lenard recursion sequences, we construct a nonisospectral generalized 3 × 3 Ablowitz–Kaup–Newell–Segur (AKNS) integrable hierarchy.

A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.
