Table I From Topological Duality In Floquet And Non Hermitian Dynamical

Table I From Topological Duality In Floquet And Non Hermitian Dynamical According to conventional theory, bulk anomalous gapless states are prohibited in lattices. however, floquet and non hermitian systems may dynamically realize such quantum anomalies in the bulk. here, we present an extension of the nielsen ninomiya theorem that is valid even in the presence of the bulk quantum anomaly. particularly, the extended theorem establishes the exact correspondence. The non hermitian system with lsv shows a non hermitian skin effect, and its topological phase can be characterized by mapping it to the hermitian system via a noncompact u(1) gauge transformation.

Non Hermitian Floquet Topological Matter A Schematic Diagram To Non hermiticity is expected to add far more physical features to the already rich floquet topological phases of matter. nevertheless, a systematic approach to characterize non hermitian floquet topological matter is still lacking. in this work we introduce a dual scheme to characterize the topology of non hermitian floquet systems in momentum space and in real space using a piecewise quenched. F as a non hermitian hamilto nian h, we treat a periodically driven system and a non hermitian one in a uni ed manner. another key is mul tiple gap structures intrinsic to non hermitian systems. the complex energy spectrum of non hermitian systems may introduce two di erent gap structures: point and line gaps [80, 81]. In this work, we consider a one dimensional non hermitian lattice model induced by partially asymmetric coupling with time periodic and spatially periodic modulations upon on site potentials. within floquet theorem, we obtain the floquet quasienergy spectrum of this one dimensional non hermitian system. we show that the robust zero energy modes. Periodically driven non hermitian quantum systems have become the center of interest in recent years due to their rich physical phenomena. in this work, we consider a one dimensional non hermitian lattice model induced by partially asymmetric coupling with time periodic and spatially periodic modulations upon on site potentials. within floquet theorem, we obtain the floquet quasienergy.

Non hermitian topological phases in static and periodically driven systems have attracted great attention in recent years. finding dynamical probes for these exotic phases would be of great importance for the detection and application of their topological properties. in this work, we introduce an approach to dynamically characterize non hermitian floquet topological phases in one dimension. At resonant driving, we draw a connection between floquet and non hermitian topology by using a duality that identifies time evolution operators with non hermitian hamiltonians.
