Entangling Power Dynamics: Ergodicity and Mixing
Rahul V, Ranjan Modak, Shaon Sahoo +1
We study quantum dynamics through the lens of entanglement generation and characterize the underlying unitary evolution by the distinct signatures it imprints on the time-dependent…
Entanglement structure for finite system under dual-unitary dynamics
Gaurav Rudra Malik, Rohit Kumar Shukla, Sudhanva Joshi +2
The dynamics of quantum many-body systems in the chaotic regime are of particular interest due to the associated phenomena of information scrambling and entanglement generation wit…
Krylov complexity in ergodically constrained nonintegrable transverse-field Ising model
Gaurav Rudra Malik, Jeet Sharma, Rohit Kumar Shukla +2
The nonintegrable transverse-field Ising model is a common platform for studying ergodic quantum dynamics. In this work, we introduce a simple variant of the model in which this er…
Diagnosing chaos in a periodically driven Ising model with a ramping field via out-of-time-order correlation saturation
Rohit Kumar Shukla, Gaurav Rudra Malik, S. Aravinda +1
The dynamic region of out-of-time-ordered correlators (OTOCs) serves as a powerful indicator of chaos in classical and semiclassical systems, capturing the characteristic exponenti…
Characterizing quantum dynamics using multipartite entanglement generation
Gaurav Rudra Malik, Rohit Kumar Shukla, S. Aravinda +1
Entanglement is a defining feature of many-body quantum systems and is an essential requirement for quantum computing. It is therefore useful to study physical processes which gene…
