Driven-dissipative topological phases in parametric resonator arrays
Álvaro Gómez-León, Tomás Ramos, Alejandro González-Tudela +1
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and expone…

Decimation technique for open quantum systems: a case study with driven-dissipative bosonic chains
Álvaro Gómez-León, Tomás Ramos, Diego Porras +1
The unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics, which can be radically different from closed-system scenario…
