Floquet Recurrences in the Double Kicked Top
Avadhut V. Purohit, Udaysinh T. Bhosale
We study exact quantum recurrences in the double kicked top (DKT), a driven spin model that extends the quantum kicked top (QKT) by introducing an additional time-reversal symmetry…
Strong Eigenstate Thermalization from Mean-Ergodic Non-chaotic Dynamics
Avadhut V. Purohit, Harshit Sharma, Udaysinh T. Bhosale
We report an example of a many-body system, derived from the double kicked top (DKT), with non-chaotic yet mean-ergodic dynamics that displays \textit{strong} eigenstate thermaliza…
Higher-order spacings in the superposed spectra of random matrices with comparison to spacing ratios and application to complex systems
Sashmita Rout, Udaysinh T. Bhosale
Higher-order spacing statistics in the superposed spectra of circular random matrices of the same class are studied numerically. We conjecture that for given (or order )…
Quantum Kicked Top: A Paradigmatic Model
Avadhut V. Purohit, Udaysinh T. Bhosale
The quantum kicked top (QKT) is one of the most widely studied models in quantum chaos, providing a minimal yet powerful framework for exploring the relationship between classical…
Exact Solvability Of Entanglement For Arbitrary Initial State in an Infinite-Range Floquet System
Harshit Sharma, Udaysinh T. Bhosale
Sharma and Bhosale [\href{https://journals.aps.org/prb/abstract/10.1103/PhysRevB.109.014412}{Phys. Rev. B \textbf{109}, 014412 (2024)}; \href{https://journals.aps.org/prb/abstract/…
Exact Solvability and Integrability Signatures in a Periodically Driven Infinite-Range Spin Chain: The Case of Floquet interval
Harshit Sharma, Sashmita Rout, Avadhut V. Purohit +1
We study the signatures of quantum integrability (QI) in a spin chain model, having infinite-range Ising interaction and subjected to a periodic pulse of an external magnetic field…
