Boundary singular scattering enables coherent perfect absorption and lasing without resonators
Letian Yu, Xu Zheng, Cesare Soci +2
Scattering singularities are features conventionally associated with resonant scattering bodies, which correspond to the zeros and poles of a scattering matrix, and manifest as coh…
Dirac branch-cut modes with relativistic transport
Bofeng Zhu, Chengzhi Ma, Qiang Wang +6
Emergent Dirac fields, exhibiting effective relativistic physics, are most commonly associated with bulk and surface states in materials such as graphene and topological insulators…
Topological antilaser
Rui-Chang Shen, Chunquan Peng, Bingbing Wang +6
Coherent perfect absorption (CPA)-the time-reversed operation of lasing at threshold-relies on finely tuned interference and is intrinsically fragile to disorder and structural imp…
Continuum Landau surface states in a non-Hermitian Weyl semimetal
Shuxin Lin, Rimi Banerjee, Zheyu Cheng +3
The surface states of certain topological phases can be linked to a quantum anomaly: the violation of a classical symmetry by a field theory via a non-conserved current. This has b…
Switchable Non-Hermitian Skin Effect in Bogoliubov Modes
Hsuan Lo, You Wang, Rimi Banerjee +2
Interacting or nonlinear lattices can host emergent particle-like modes, such as Bogoliubov quasiparticles, whose band topology and other properties are potentially highly tunable.…
Topological disclination states and charge fractionalization in a non-Hermitian lattice
Rimi Banerjee, Subhaskar Mandal, Yun Yong Terh +4
We show that a non-Hermitian lattice with a disclination can host topological disclination states that are induced by on-site gain and loss. The disclination states are inherently…
Dirac mass induced by optical gain and loss
Letian Yu, Haoran Xue, Ruixiang Guo +5
Mass is commonly regarded as an intrinsic property of matter, but modern physics reveals particle masses to have complex origins, such as the Higgs mechanism in high-energy physics…
