Long-Range Order in Coupled -dimensional Kuramoto Oscillators
Zhongpu Qiu, Tianyi Wu, Linkai Zhang +4
We show that the long-range order (LRO) strikingly emerges in systems of locally coupled -dimensional vector Kuramoto oscillators on low-dimensional lattices (), but only…
Multimodal Terahertz Spectroscopy of the Pairing Symmetry and Normal-State Pseudogap in (La,Pr)NiO Films
Shuxiang Xu, Guangdi Zhou, Hao Wang +11
The discovery of ambient-pressure superconductivity in compressively strained (La,Pr)NiO thin films has intensified efforts to identify the pairing mechanism. However,…
Anomalous terahertz nonlinearity in disordered s-wave superconductor close to the superconductor-insulator transition
Hao Wang, Jiayu Yuan, Hongkai Shi +13
Detection of the Higgs mode in superconductors using nonlinear terahertz spectroscopy is a key area of interest in condensed matter physics. We investigate the influence of disorde…
Criticality and Universality of Generalized Kuramoto Model
Zhongpu Qiu, Tianyi Wu, Sheng Fang +2
We explore synchronization transitions in even--dimensional generalized Kuramoto oscillators on both complete graphs and -dimensional lattices. In the globally coupled system…
Selective excitation of collective modes in multiband superconductor MgB2
Jiayu Yuan, Liyu Shi, Tiequan Xu +7
Recent developments in nonequilibrium and nonlinear terahertz (THz) spectroscopies have significantly advanced our understanding of collective excitations in superconductors. Howev…
