Asymptotic Metrological Scaling and Concentration in Chaotic Floquet Dynamics
Astrid J. M. Bergman, Yunxiang Liao, Jing Yang
We study quantum sensing with Floquet chaotic dynamics generated by Haar random unitary gates. The metrological resources consist of three ingredients: A given initial state, a set…

Exact Quantum Dynamics, Shortcuts to Adiabaticity, and Quantum Quenches in Strongly-Correlated Many-Body Systems: The Time-Dependent Jastrow Ansatz
Jing Yang, Adolfo del Campo
The description of strongly correlated quantum many-body systems far from equilibrium presents a fundamental challenge due to the vast amount of information it requires. We introdu…
