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…
Dynamics of Majorana zero modes across hybrid Kitaev chain
Rajiv Kumar, Rohit Kumar Shukla, Levan Chotorlishvili +1
The Kitaev chain has been extensively explored in the context of uniform couplings, with studies focusing either on purely nearest-neighbor interactions or on systems dominated by…
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…
Out-of-time-order correlation in the quantum Ising Floquet spin system and magnonic crystals
Rohit Kumar Shukla
In recent times out-of-time-order correlators (OTOC) have been established as a tool to understand butterfly effects, quantum information scrambling, and many-body localization. Th…
