Flow topology classification of limit cycles
Thomas Mutschler, Greta Villa, Oded Zilberberg
Recent topological tools offer a powerful way to classify how phases of nonlinear bosonic resonators are organized. Yet, they remain incomplete. In particular, self-sustained oscil…
Manifestations of flow topology in a quantum driven-dissipative system
Kilian Seibold, Greta Villa, Javier del Pino +1
In driven-dissipative bosonic systems, the interplay between coherent driving, inter-particle interactions and dissipation leads to a rich variety of non-equilibrium stationary sta…
Mean-chiral displacement in coherently driven photonic lattices and its application to synthetic frequency dimensions
Greta Villa, Iacopo Carusotto, Tomoki Ozawa
Characterizing topologically nontrivial photonic lattices by measuring their topological invariants is crucial in topological photonics. In conservative one-dimensional systems, a…
Topological classification of driven-dissipative nonlinear systems
Greta Villa, Javier del Pino, Vincent Dumont +4
In topology, one averages over local geometrical details to reveal robust global features. This approach proves crucial for understanding quantized bulk transport and exotic bounda…
