Hybrid Higher-Order Skin-Topological Modes in Nonreciprocal Systems
Hybrid Higher-Order Skin-Topological Modes in Nonreciprocal Systems
Higher-order phases are characterized by corner or hinge modes that arise due to the interesting interplay of localization mechanisms along two or more dimensions. In this work, we introduce and construct a novel class of ``hybrid'' higher-order skin-topological boundary modes in nonreciprocal systems with two or more open boundaries. Their …
