嵌合态是空间相干和非相干动力学共存的一种状态,在过去的十年中得到了广泛的研究。本文报道了一维非局域耦合量子选择子环中的一种特殊的嵌合态--2-频率嵌合态。在二频嵌合态中,存在两种相干畴,不同相干畴中的振子具有不同的平均相速度。给出了二频嵌合态的稳定性图,并研究了二频嵌合态与普通二簇嵌合态之间的过渡。
Chimera states, which consist of coexisting domains of spatially coherent and incoherent dynamics, have been intensively investigated in the past decade. In this work, we report a special chimera state, 2-frequency chimera state, in one-dimensional ring of nonlocally coupled Brusselators. In a 2-frequency chimera state, there exist two types of coherent domains and oscillators in different types of coherent domains have different mean phase velocities. We present the stability diagram of 2-frequency chimera state and study the transition between the 2-frequency chimera state and an ordinary 2-cluster chimera state.
