WebNov 17, 2024 · Abstract The non-Hermitian skin effect is a unique feature of non-Hermitian systems, in which an extensive number of boundary modes appear under the open boundary conditions. Here, we discover higher-order counterparts of the non-Hermitian skin effect that exhibit new boundary physics.

In mathematics, in the field of differential equations, a boundary value problem is a differential equation together with a set of additional constraints, called the boundary conditions. A solution to a boundary value problem is a solution to the differential equation which also satisfies the boundary conditions. Boundary value problems arise in several branches of physics as any physica… WebApr 10, 2024 · These topological boundary states are originated from two consecutive square-root procedures which is similar to the square-root topological insulators. Our work provides a brand-new approach to achieve the multiple boundary states by simply inserting additional cavities without elaborate designing the structure, which makes the …
WebApr 7, 2024 · The boundary layer theory in fluid mechanics states that when a fluid has a relative motion to the surface, the liquid particles next to it adheres. This adhering mechanism is known as the 'no-slip condition. Through viscosity, this layer then creates a barrier or resists the next layer, thus slowing it down, which, in turn, affects the layer ...
