Magic Without Entanglement: Exact Revivals and Their Fisher Information Origin
Rishabh Jha, Karun Gadge
The paper explores the relationship between quantum magic and entanglement, showing how stabilizer Rényi entropy curvature relates to quantum Fisher information and constructing mo…
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 …
A comparative study of perturbative and nonequilibrium Green's function approaches for Floquet sidebands in periodically driven quantum systems
Karun Gadge, Marco Merboldt, Michael Schüler +6
We compare two complementary theoretical approaches to compute and interpret Floquet sidebands in periodically driven quantum materials: a first-order perturbative approach (first-…
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…
Observation of Floquet states in graphene
Marco Merboldt, Michael Schüler, David Schmitt +11
Recent advances in the field of condensed-matter physics have unlocked the potential to realize and control emergent material phases that do not exist in thermal equilibrium. One o…
