Characteristic, dynamic, and near saturation regions of Out-of-time-order correlation in Floquet Ising models
Rohit Kumar Shukla, Sunil Kumar Mishra
We study characteristic, dynamic, and saturation regimes of the out-of-time-order correlation (OTOC) in the constant field Floquet system with and without longitudinal field. In th…
Out-of-time-order correlators of nonlocal block-spin and random observables in integrable and nonintegrable spin chains
Rohit Kumar Shukla, Arul Lakshminarayan, Sunil Kumar Mishra
Out-of-time-order correlators (OTOC) in the Ising Floquet system, that can be both integrable and nonintegrable is studied. Instead of localized spin observables, we study contiguo…
Directional scrambling of quantum information in helical multiferroics
M. Sekania, M. Melz, N. Sedlmayr +2
Local excitations as carriers of quantum information spread out in the system in ways governed by the underlying interaction and symmetry. Understanding this phenomenon, also calle…
Quantum teleportation by utilizing helical spin chains for sharing entanglement
Harshit Verma, Levan Chotorlishvili, Jamal Berakdar +1
We develop a new protocol for sharing entanglement (one ebit) between two parties using the natural dynamics of helical multiferroic spin chains. We introduce a novel kicking schem…
Out-of-time-order correlation and detection of phase structure in Floquet transverse Ising spin system
Rohit Kumar Shukla, Gautam Kamalakar Naik, Sunil Kumar Mishra
We study the out-of-time-order correlation (OTOC) of the Floquet transverse Ising model and use it to verify the phase diagram of the system. First, we present the exact analytical…
Analytical solutions of inhomogeneous transverse field Ising models
Abhijit P. Chaudhari, Rajeev Singh, Sunil K. Mishra
The inhomogeneous transverse field Ising models mainly impurity based and the joint chain are analysed analytically using Jordan-Wigner transformations. The effects of inhomogeneit…
