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…
