Adiabatic Ramsey Interferometry for Measuring Weak Nonlinearities with Super-Heisenberg Precision
Venelin P. Pavlov, Bogomila S. Nikolova, Peter A. Ivanov
We propose an adiabatic Ramsey interferometry technique for detecting weak nonlinearities with trapped ions. The method relies on using the quantum Rabi model as a probe, which is…

Probing the ergodicity breaking transition via violations of random matrix theoretic predictions for local observables
Venelin P. Pavlov, Peter A. Ivanov, Diego Porras +1
Quantum many-body systems can exhibit distinct regimes where dynamics is either ergodic, dynamically exploring an extensive region of available state-space, or non-ergodic, where t…

Analytical determination of multi-time correlation functions in quantum chaotic systems
Yoana R. Chorbadzhiyska, Peter A. Ivanov, Charlie Nation
The time-dependence of multi-point observable correlation functions are essential quantities in analysis and simulation of quantum dynamics. Open quantum systems approaches utilize…
