Singular geometry and eigenframe topology in local rank-2 tensor observables
I. C. J. Yap, B. Doerschel, S. Q. Jin +6
The paper investigates how symmetric second‑rank tensors, exemplified by the electric‑field‑gradient (EFG) tensor, develop singularities and a topological return‑parity when eigenv…

Magneto-electric decoupling in bismuth ferrite
Thien Thanh Dang, Juliana Heiniger-Schell, Astita Dubey +8
It is still under intensive discussion, how magnetoelectric coupling actually occurs at the atomic scale in multiferroic BiFeO3. Nuclear solid-state techniques monitor local fields…
