Dissipation driven boundary localization in higher order topological insulators
Xue Ping Ren, Xiao Ran Wang, Xin Ran Ma +2
We study dissipation driven boundary localization in a Bernevig Hughes Zhang type second order topological insulator by introducing inhomogeneous, spin dependent boundary dissipati…
Tuning Topological States by Dissipation
Xue-Ping Ren, Yue Hu, Long-Ye Lu +4
The bulk-boundary correspondence plays a crucial role in topological quantum systems, however,this principle is broken in non-Hermitian systems. The breakdown of the bulk-boundary…
A Unified Framework for the Non-Hermitian Localization: Boundary-Insensitive Modes and Electric-Magnetic Analogy
Zheng Wei, Ji-Yao Fan, Kui Cao +4
The non-Hermitian skin effect is fundamentally characterized by its sensitivity to boundary conditions, reflected in changes to the energy spectrum and boundary-localized eigenstat…
Non-Hermitian tearing by dissipation
Qian Du, Xin-Ran Ma, Su-Peng Kou
In the paper, we study the non-Hermitian system under dissipation and give the effective 2*2 Hamiltonian in the k-space by reducing the N*N Hamiltonian in the real space for them.…
