Two-dimensional localized modes in nonlinear systems with linear nonlocality and moiré lattices被引量：1
《Frontiers of physics》2024年第4期265-273,共9页Xiuye Liu Jianhua Zeng 
This work was supported by the National Natural Science Foundation of China(NSFC)(No.12074423);Young Scholar of Chinese Academy of Sciences in Western China(No.XAB2021YN18);China Postdoctoral Science Foundation(No.2023M733722).
Periodic structures structured as photonic crystals and optical lattices are fascinating for nonlinear waves engineering in the optics and ultracold atoms communities.Moiréphotonic and optical lattices—two-dimension...

Quantum simulation of Hofstadter butterfly with synthetic gauge fields on two-dimensional superconducting-qubit lattices
《Frontiers of physics》2023年第6期283-290,共8页Wei Feng Dexi Shao Guo-Qiang Zhang Qi-Ping Su Jun-Xiang Zhang Chui-Ping Yang 
supported by the National Natural Science Foundation of China (Grant Nos.12204139,U20A2076,12204138,12205069,11774076,and U21A20436);the Key-Area Research and Development Program of Guangdong Province (Grant No.2018B030326001).
Motivated by recent realizations of two-dimensional(2D)superconducting-qubit lattices,we propose a protocol to simulate Hofstadter butterfly with synthetic gauge fields in superconducting circuits.Based on the existin...

High-order exceptional points in non-Hermitian Moire lattices被引量：1
《Frontiers of physics》2019年第5期81-87,共7页Yan-Rong Zhang Ze-Zheng Zhang Jia-Qi Yuan Ming Kang Jing Chen 
Y. R. Z., Z. Z. Z., and J. Q. Y. contributed equally to this study. The authors acknowledge support from the National Natural Science Foundation of China (NSFC) under Grant Nos. 11574162, 11674244, and 11874228.
This study proposes an approach to generate high-order exceptional points (EPs) in non-Herniitian systems.A system comprising a homogenous waveguide is considered wlierein the imaginary part of the refractive index is...

Discrete vortices on anisotropic lattices被引量：1
《Frontiers of physics》2015年第4期55-60,共6页Gui-Hua Chen Hong-Cheng Wang Zi-Fa Chen 
We consider the effects of anisotropy on two types of localized states with topological charges equal to 1 in two-dimensional nonlinear lattices, nsing the discrete nonlinear SchrSdinger equation as a paradigm model. ...

Propagation dynamics on the Fermi-Pasta-Ulam lattices被引量：1
《Frontiers of physics》2013年第3期349-355,共7页Zong-Qiang Yuan Zhi-Gang Zheng 
Acknowledgements Project supported by the National Natural Science Foundation of China （Grant No. 11075016）, the Fundamental Research Funds for the Central Universities of China （Grant No. 201001）, and the Research and for the Doctoral Program of Higher Education of China （Grant No. 20100003110007）.
The spatiotemporal propagation of a momentum excitation on the finite Fermi-Pasta-Ulam lattices is investigated. The competition between the solitary wave and phonons gives rise to interesting propagation behaviors. F...
