Quantum memory and scrambling from the perspective of a classical neural network
Dimitrios Maroulakos, Andrzej Wal, Marcin Kowalik +4
Entropic uncertainty relations are universal quantifiers of fundamental uncertainties of quantum measurements and are widely discussed in the quantum metrology literature. Quantum…
Many-Body Structural Effects in Periodically Driven Quantum Batteries
Rohit Kumar Shukla, Cheng Shang
While quantum batteries have been widely studied under static driving, their performance under periodic driving in many-body systems has received only limited attention. In this Le…
Collective dynamics versus entanglement in quantum battery performance
Rohit Kumar Shukla, Sunil K. Mishra, Ujjwal Sen
We investigate charging dynamics in many-body quantum batteries by examining the relationship between instantaneous charging power and the emergence of bipartite, tripartite, and m…
Dynamical onset of quasiprobability negativity in quantum many-body systems
Rohit Kumar Shukla, Amikam Levy
Time-dependent quasiprobability distributions provide a quasiprobabilistic description of sequential measurement statistics generated by quantum dynamics, and can reveal nonclassic…
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…
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…
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…
System versus charger in performance optimization of quantum batteries
Rohit Kumar Shukla, Rajiv Kumar, Ujjwal Sen +1
Quantum batteries provide a platform for investigating energy storage and extraction in quantum many-body systems. Here, we study a charging protocol in which battery and chargoid…
Prethermal Floquet time crystals in chiral multiferroic chains and applications as quantum sensors of AC fields
Rohit Kumar Shukla, Levan Chotorlishvili, Sunil K. Mishra +1
We study the emergence of prethermal Floquet Time Crystal (pFTC) in disordered chiral multiferroic chains. The model is an extension of the usual periodically driven nearest-neighb…
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…
Scrambling in Ising spin systems with periodic transverse magnetic fields
Rohit Kumar Shukla
Scrambling of quantum information in both integrable and nonintegrable Floquet spin systems is studied. Our study employs tripartite mutual information (TMI), with negative TMI ser…
