Tailoring Corner States and Exceptional Points in Altermagnets

Xiao-Ming Zhao, Cui-Xian Guo, Xin-Ran Ma +2

Altermagnets (AMs) exhibit vanishing net magnetization but strong momentum-dependent spin splitting enforced by crystal symmetry. Here, we explore the non-Hermitian effects in diss…

Topological phases in the periodically kicked Chern insulators

Fei Yang, Zheng Wei, TianMeng Li +1

Novel topological properties that arose in the periodically driven system are unique, in which there are two kinds of quasienergy gaps, the zero quasienergy gap and the quasien…

Topological phases of many-body non-Hermitian systems

Kui Cao, Su-Peng Kou

We show that many-body fermionic non-Hermitian systems require two distinct sets of topological invariants to describe the topology of energy bands and quantum states respectively,…

First-order Quantum Phase Transitions and Localization in the 2D Haldane Model with Non-Hermitian Quasicrystal Boundaries

Xianqi Tong, Su-Peng Kou

The non-Hermitian extension of quasicrystals (QC) are highly tunable system for exploring novel material phases. While extended-localized phase transitions have been observed in on…

Non-Hermitian Chiral Edge Modes With Complex Fermi Velocity

Fei Yang, Xue-Ping Ren, Su-peng Kou

Recently, much attention has been paid to uncovering the influence of dissipation on a quantum system, particularly on how the non-Hermitian (NH) terms modify the band topology of…

Aufbau Principle for Non-Hermitian Systems

Gaoyong Sun, Su-Peng Kou

We develop a generalized Aufbau principle for non-Hermitian systems that allows for building up the configurations of indistinguishable particles. The Aufbau rule of non-Hermitian…
