Dissipative phase transitions and chaos in two-photon driven quantum optomechanics
Giovanni Bragadin, Filippo Ferrari, Lorenzo Fioroni +4
The paper studies a two‑photon‑driven optomechanical system, showing it can exhibit both first‑ and second‑order dissipative phase transitions, symmetry breaking, and chaotic dynam…
Floquet Dissipative Phase Transitions
Alberto Mercurio, Vincenzo Macrì, Filippo Ferrari +2
Dissipative phase transitions (DPTs) are traditionally characterized through the spectrum of a time-independent Liouvillian superoperator. However, this definition does not apply t…
Density Wave Ordering with Disordered Ultracold Fermions in Optical Cavities
Ãscar Rios Alves, Filippo Ferrari, Lorenzo Fioroni +2
We investigate the interplay between cavity-induced density-wave ordering and controllable disorder in a trapped two-dimensional gas of ultracold fermions. The atoms are dispersive…
Superstrong Dynamics and Directional Emission of a Giant Atom in a Structured Bath
Vincent Jouanny, Léo Peyruchat, Marco Scigliuzzo +8
Quantum emitters coupled to waveguides with nonlinear dispersion show rich quantum dynamics with the promise of implementing non-trivial non-Markovian quantum models. Recent advanc…
AlgoTune: Can Language Models Speed Up General-Purpose Numerical Programs?
Ori Press, Brandon Amos, Haoyu Zhao +21
Despite progress in language model (LM) capabilities, evaluations have thus far focused on models' performance on tasks that humans have previously solved, including in programming…
Chiral cat code: Enhanced error correction induced by higher-order nonlinearities
Adrià Labay-Mora, Alberto Mercurio, Vincenzo Savona +2
We introduce a Schrödinger chiral cat qubit, a novel bosonic quantum code generalizing Kerr cat qubits that exploits higher-order nonlinearities. Compared to a standard Kerr cat,…
