论文摘要
自从发现嵌合体状态以来，非零相位滞后参数的存在被证明是嵌合体在非局限耦合相同的库拉莫托相振荡器与成对相互作用的网络中出现的重要属性。在这封信中，我们报告了由于引入了非偶然性相互作用而在非局部耦合相同的库拉莫托网络中没有相位滞后的嵌合体的出现。耦合系统动力学中添加的非线性以简单复合物的形式减轻了嵌合态出现的非零相位滞后参数的必要条件。由成对和非二线相互作用强度及其多稳态的互惠性刺激的嵌合体状态以适当的措施进行了表征，并在参数空间中得到了证明。
Since the discovery of chimera states, the presence of a nonzero phase lag parameter turns out to be an essential attribute for the emergence of chimeras in a nonlocally coupled identical Kuramoto phase oscillators' network with pairwise interactions. In this letter, we report the emergence of chimeras without phase lag in nonlocally coupled identical Kuramoto network owing to the introduction of non-pairwise interactions. The influence of added nonlinearity in the coupled system dynamics in the form of simplicial complexes mitigates the requisite of a nonzero phase lag parameter for the emergence of chimera states. Chimera states stimulated by the reciprocity of the pairwise and non-pairwise interaction strengths and their multistable nature are characterized with appropriate measures and are demonstrated in the parameter spaces.
