(Non-)Traversable Quantum Phase Transitions
Federico Balducci, Paul M. Schindler, Andrea Solfanelli +1
Quantum phase transitions manifest as an abrupt change in the ground state of a many-body system; yet it is an open question whether this sudden change necessarily precludes a cont…
Robust spin-squeezing with random interaction graphs: the lesson from universality
Andrea Solfanelli, Augusto Smerzi, Peter Zoller +1
We establish the conditions under which scalable spin squeezing can be achieved in interacting spin ensembles embedded in arbitrary, inhomogeneous graph geometries. We identify two…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Universality and weak-ergodicity breaking in quantum quenches
Guido Giachetti, Andrea Solfanelli, Nicolò Defenu
Understanding equilibration and universality after sudden quantum quenches remains a central challenge in isolated many-body systems. Persistent oscillations and anomalous scaling…
The long-range origin of the black hole entropy
Andrea Solfanelli, Francesco Petocchi, Nicolò Defenu
The Sachdev-Ye-Kitaev (SYK) model, has emerged as a powerful tool for exploring the quantum nature of black holes, particularly their residual entropy at zero temperature. In this…
