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…
Non-Hermitian skin effect induced by spatial noncommutativity
Zheng Wei, Su-Peng Kou
In all known schemes for the non-Hermitian skin effect, the non-Hermitian ingredient that drives the skin localization, whether asymmetric hopping or gain and loss, is invariably i…
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…
Quantum Physics -- A Theory of Dynamics for "Space" on Space
Su-Peng Kou
Till now, the foundation of quantum physics is still mysterious. To explore the mysteries in the foundation of quantum physics, people always take it for granted that quantum proce…
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…
Deconfined quantum criticality of frustrated hard-core dipolar bosons
Ya-Nan Wang, Wen-Long You, Wen-Yi Zhang +2
Deconfined quantum critical points (DQCPs) are proposed as unconventional second-order phase transitions beyond the Landau-Ginzburg-Wilson paradigm. The nature and experimental rea…
