Driven-dissipative topological phases in parametric resonator arrays
Driven-dissipative topological phases in parametric resonator arrays
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and exponential gain with the number of sites, and one of them featuring squeezing. We also find a topologically trivial phase with zero-energy modes which produces amplification …
