We show the spin swapping effect originated from band structure in centrosymmetric ferromagnets. Without breaking inversion symmetry or introducing spin-orbit impurities, the effect is attributed to ...

New works presents a unified theoretical framework to describe the electronic structure of non-Hermitian systems, potentially leading to major advancements in condensed matter physics ...

Wave digital filter (WDF) structures for high-speed narrow-band and wide-band filtering are introduced. The narrow-band filter is composed of a periodic model filter and one or several, possibly ...
