  The relation of topological insulators and superconductors and the field of
nonlinear dynamics is widely unexplored. To address this subject, we adopt the
linear coupling geometry of the Su-Schrieffer-Heeger model, a paradigmatic
example for a topological insulator, and render it nonlinearly in the context
of superconducting circuits. As a consequence, the system exhibits
topologically-enforced bifurcations as a function of the topological control
parameter, which finally gives rise to chaotic dynamics, separating phases
which exhibit clear topological features.
