Breakdown of Measurement-Induced Phase Transitions Under Information Loss
Alessio Paviglianiti, Giovanni Di Fresco, Alessandro Silva +3
The dynamics of a quantum-many body system subject to measurements is naturally described by an ensemble of quantum trajectories, which can feature measurement-induced phase transi…
Effects of correlated noise on the excitation of robust breathers in an ac-driven, lossy sine-Gordon system
Giovanni Di Fresco, Duilio De Santis, Claudio Guarcello +3
Thermal noise and harmonic forcing have recently been shown to cooperatively excite sine-Gordon breathers robust to dissipation. Such a phenomenon has been found assuming a Gaussia…
Entanglement growth in the dark intervals of a locally monitored free-fermion chain
Giovanni Di Fresco, Youenn Le Gal, Davide Valenti +3
We consider a free fermionic chain with monitoring of the particle density on a single site of the chain and study the entanglement dynamics of quantum jump trajectories. We show t…
Quantum optics with giant atoms in a structured photonic bath
L. Leonforte, X. Sun, D. Valenti +4
We present a general framework to tackle quantum optics problems with giant atoms, i.e. quantum emitters each coupled {\it non-locally} to a structured photonic bath (typically a l…
