Non-Bloch Band Theory of Non-Hermitian Systems

WebHere, we introduce a non-Hermitian tight-binding model to reveal the interplay between the topological energy braiding and the non-Hermitian skin effect of the open systems. Surprisingly, the non-Hermitian skin effect can induces the topological energy braiding of the non-Bloch bands in open systems such as Hopf link, despite the topologically ... WebAbstract: We study the quench dynamics of non-Hermitian topological models with non-Hermitian skin effects. Adopting the non-Bloch band theory and projecting quench dynamics onto the generalized Brillouin zone, we find that emergent topological structures, in the form of dynamic skyrmions, exist in the generalized momentum-time domain, and are ... polyurethane stained by inkWebIn contrast to the various knots residing in the 3D k-space and formed by the zero-energy nodal lines of topological semimet- als [80{93], the knots here live in the energy … shannon imx
