Abstract: Measurement-induced phases exhibit unconventional dynamics as emergent collective phenomena, yet their behavior in tailored interacting systems – crucial for quantum technologies – remains less understood. We develop a systematic toolbox to analyze monitored dynamics in… read more here.

Abstract: We investigate energy diffusion in long-range interacting spin systems, where the interaction decays algebraically as V(r)∝r^{-α} with the distance r between the sites. We consider prototypical spin systems, the transverse Ising model, and the XYZ… read more here.

DOI: 10.1103/physrevlett.121.240403
Abstract: Slow quenches of the magnetic field across the paramagnetic-ferromagnetic phase transition of spin systems produce heat. In systems with short-range interactions the heat exhibits universal power-law scaling as a function of the quench rate, known… read more here.

DOI: 10.1103/physrevlett.128.010604
Abstract: The competition between scrambling unitary evolution and projective measurements leads to a phase transition in the dynamics of quantum entanglement. Here, we demonstrate that the nature of this transition is fundamentally altered by the presence… read more here.
