Annalen der Physik, Volume 538, Issue 2, February 2026.A uniform torsion field—representing a controlled density of parallel screw dislocations—confines a single electron into a geometry‐defined quantum dot. In a perpendicular magnetic field, an Aharonov–Bohm flux breaks the m↔−m$m \leftrightarrow -m$ symmetry and yields a flux‐ and torsion‐tunable angular pseudospin (m=±1)$(m = \pm 1)$ with asymmetric ...

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics
Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

Analyzing the Free States of one Quantum Resource Theory as Resource States of Another
Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.The article investigates how free states in one quantum resource theory can become highly resourceful in another. It systematically studies multipartite entanglement, fermionic non‐Gaussianity, imaginarity, realness, spin coherence, Clifford non‐stabilizerness, Sn‐equivariance, and non‐uniform entanglement, combining rigorous analytical tools and ...
