Abstract

Numerical simulations indicate that a stack of intrinsic Josephson junctions, as may be realized in a high temperature superconductor, can exhibit breathing chimera states. Previously, such states had only been reported for systems containing two populations, for which the coupling strength between oscillators in one population differed from that between the two populations. This is the first time that breathing chimera states have been observed in simulations of identical oscillators that are also identically coupled. Moreover, in a mechanical sense, the nature of the coupling in the present system corresponds to a non-trivial inertial coupling, which has not been explored previously.
