Insight of the Green's function as a defect state in a boundary value problem
Jose D. H. Rivero, Li Ge
A new perspective of the Green's function in a boundary value problem as the only eigenstate in an auxiliary formulation is introduced. In this treatment, the Green's function can…
Origin of robust exceptional points: a restricted bulk zero mode
Jose D. H. Rivero, Li Ge
Recently a type of robust exceptional points was found that is insensitive to the coupling disorder in the bulk. Here we show that a disparity emerges when the number of coupled ca…
Stable Switching among High-Order Modes in Polariton Condensates
Yongbao Sun, Yoseob Yoon, Saeed Khan +6
We report multistate optical switching among high-order bouncing-ball modes ("ripples") and whispering-gallerying modes ("petals") of exciton-polariton condensates in a laser-gener…
Pattern Formation and Strong Nonlinear Interactions in Exciton-Polariton Condensates
Li Ge, Ani Nersisyan, Baris Oztop +1
Exciton-polaritons generated by light-induced potentials can spontaneously condense into macroscopic quantum states that display nontrivial spatial and temporal density modulation.…
