Observation of geometry-dependent skin effect in non-Hermitian phononic crystals with exceptional points
Observation of geometry-dependent skin effect in non-Hermitian phononic crystals with exceptional points
Exceptional points and skin effect, as the two distinct hallmark features unique to the non-Hermitian physics, have each attracted enormous interests. Recent theoretical works reveal that the topologically nontrivial exceptional points can guarantee the non-Hermitian skin effect, which is geometry-dependent, relating these two unique phenomena. However, such novel relation remains …
