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…
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 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…
Study of double kicked top: a classical and quantum perspective
Avadhut V. Purohit, Udaysinh T. Bhosale
We study the double kicked top (DKT), which is an extension of the standard quantum kicked top (QKT) model. The model allows us to study the transition from time-reversal symmetric…
