Magic Without Entanglement: Exact Revivals and Their Fisher Information Origin
Rishabh Jha, Karun Gadge
Magic and entanglement are independent quantum resources, yet their exact relation in many-body dynamics has remained elusive. We uncover two structural principles. First, at any s…

Temporal Entanglement Transitions in the Periodically Driven Ising Chain
Karun Gadge, Abhinav Prem, Rishabh Jha
Periodically driven quantum systems can host non-equilibrium phenomena without static analogs, including in their entanglement dynamics. Here, we discover …
