A Solvable Model of Quantum Darwinism-Encoding Transitions
Benoît Ferté, Xiangyu Cao
We propose a solvable model of Quantum Darwinism to encoding transitions -- abrupt changes in how quantum information spreads in a many-body system under unitary dynamics. We consi…

Surprises in the Deep Hilbert Space of all-to-all systems: From super-exponential scrambling to slow entanglement growth
Zihao Qi, Thomas Scaffidi, Xiangyu Cao
The quantum dynamics of spin systems with uniform all-to-all interaction are often studied in the totally symmetric space (TSS) of maximal total spin. However the TSS states are at…

On the analytical continuation of lattice Liouville theory
Xiangyu Cao, Raoul Santachiara, Romain Usciati
The path integral of Liouville theory is well understood only when the central charge . Here, we study the analytical continuation the lattice Liouville path int…
