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…
Dynamical Phase Transitions Across Slow and Fast Regimes in a Two-Tone Driven Duffing Resonator
Soumya S. Kumar, Javier del Pino, Letizia Catalini +2
The response of nonlinear resonators to multifrequency driving reveals rich dynamics beyond conventional single-tone theory. We study a Duffing resonator under bichromatic excitati…
Racetrack computing with a topological boundary ratchet
Parisa Omidvar, Markus Bestler, Sima Zahedi Fard +2
Multistable order parameters provide a natural means of encoding non-volatile information in spatial domains, a concept that forms the foundation of magnetic memory devices. Howeve…
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…
Time-resolved spectroscopy of noise-driven collective states of light
Diego Piciocchi, Ina Heckelmann, Alexander Dikopoltsev +6
We study a collective liquid state of light in a fast-gain laser. Controlled temporal noise on the cavity modulation creates a fluctuating linear potential along the synthetic freq…
Quantized nonlinear kink movement through topological boundary state instabilities
Markus Bestler, Oded Zilberberg
Thouless pumping is a paradigmatic example of topologically protected, directed transport in linear systems. Recent extensions to nonlinear pumps often overlook the need to reasses…
