Edge of Stability in Nonlinear Photonic Reservoirs: Universal Design Principle for Exciton-Polariton Computing
Xingran Xu, Yong-Jia Chong, Zhi-Hao Sun
Reservoir computing has emerged as a powerful paradigm for harnessing the intrinsic dynamics of physical systems to perform complex information processing. Here, we theoretically a…
Self-Decelerating Bright Exciton-Polariton Solitons in Bound-State-in-Continuum Microcavities
Xingran Xu, Chunyu Jia
We theoretically investigate the formation and dynamics of bright exciton-polariton solitons within systems engineered to support Bound States in the Continuum. By employing a driv…
Dynamic protected states in the non-Hermitian system
Lei Chen, Zhen-Xia Niu, Xingran Xu
The non-Hermitian skin effect and nonreciprocal behavior are sensitive to the boundary conditions, which are unique features of non-Hermitian systems. The eigenenergies will become…
Exciton polariton critical non-Hermitian skin effect with spin-momentum-locked gains
Xingran Xu, Lingyu Tian, Zhiyuan An +2
The critical skin effect, an intriguing phenomenon in non-Hermitian systems, displays sensitivity to system size and manifests distinct dynamical behaviors. In this work, we propos…
Spin-polarized antichiral exciton-polariton edge states
Ruiqi Bao, S. Mandal, Huawen Xu +3
We consider theoretically a system of exciton-polariton micropillars arranged in a honeycomb lattice. The naturally present TE-TM splitting and an alternating Zeeman splitting, whe…
Plasma absorption levelling by phase coherence in meta-surface stacked structure
Xing-Yu Xu, Zhong-Zhu Liang, Li Qin +1
In this paper, we propose a MIM (metallic metasurface-insulator-metal) stacked structure to realize perfect absorption in mid- and far- infrared bandwidth. A large number of metall…
Non-reciprocal Exciton-Polariton Ring Lattices

Recent experiments have shown the transfer of orbital angular momentum (OAM) from a non-resonant laser onto an exciton-polariton condensate, despite earlier views that the phase in…
Non-Hermitian topological exciton-polariton corner modes
Xingran Xu, Ruiqi Bao, Timothy C. H. Liew
We theoretically study two-dimensional exciton-polariton lattices and predict that non-Hermitian topological corner modes can be formed under non-resonant pumping. As a generalizat…
Time crystal and chaos in the hybrid atom-optomechanics system
Xingran Xu, Tanjung Krisnanda, Timothy C. H. Liew
We consider atoms in two different periodic potentials induced by different lasers, one of which is coupled to a mechanical membrane via radiation pressure force. The atoms are int…
Interaction induced bi-skin effect in an exciton-polariton system
Xingran Xu, Huawen Xu, S. Mandal +3
The non-Hermitian skin effect can be realized through asymmetric hopping between forward and backward directions, where all the modes of the system are localized at one edge of a f…
The non-Hermitian geometrical property of 1D Lieb lattice under Majorana's stellar representation
Xingran Xu, Haodi Liu, Zhidong Zhang +1
The topological properties of non-Hermitian Hamiltonian is a hot topic, and the theoretical studies along this research line are usually based on the two-level non-Hermitian Hamilt…
