Singular geometry and eigenframe topology in local rank-2 tensor observables
I. C. J. Yap, B. Doerschel, S. Q. Jin +6
Many observables are symmetric second-rank tensors, reported through magnitude-ordered principal values and axes. This chart folds tensor space: the parameters develop cusps and ex…

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…
