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 …

Stability of Floquet sidebands and quantum coherence in 1D strongly interacting spinless fermions
Karun Gadge, Salvatore R. Manmana
For strongly correlated quantum systems, fundamental questions about the formation and stability of Floquet-Bloch sidebands (FBs) upon periodic driving remain unresolved. Here, we…
