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…
Photonic bilayer Chern insulator with corner states
Subhaskar Mandal, Ziyao Wang, Rimi Banerjee +6
Photonic Chern insulators can be implemented in gyromagnetic photonic crystals with broken time-reversal (TR) symmetry. They exhibit gapless chiral edge states (CESs), enabling uni…
