“…Chimeras were studied in multilayer networks of phase oscillators, 7,[11][12][13]16,19 Hindmarsh-Rose, 7,9,10,14,18 and FitzHugh-Nagumo 27 model neurons, as well as chaotic time-discrete maps. 8,15,17 It was shown that couplings between network layers can suppress or induce [7][8][9][10][11][14][15][16][17] chimera states in individual layers and that chimeras can be identical, almost identical, or distinct across different layers. 7,8,[11][12][13][14][15][16]18 Coupling delays [8][9][10] as well as parameter mismatches or structural differences across layers 7,9,11,[15][16][17] were found to play an important role in this multilayer setting.…”
