Quantum chaos and thermalization in the two-mode Dicke model
Aleksandrina V. Kirkova, Peter A. Ivanov
We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model, which describes the dipolar interaction between an ensemble of spins and two bosonic modes. Th…
Out-of-time-order correlator in the quantum Rabi model
Aleksandrina V. Kirkova, Diego Porras, Peter A. Ivanov
We investigate signatures of chaos and equilibration in the quantum Rabi model, which exhibits a quantum phase transition when the ratio of the atomic level-splitting to bosonic fr…
Adiabatic Sensing Technique for Optimal Temperature Estimation using Trapped Ions
Aleksandrina V. Kirkova, Weibin Li, Peter A. Ivanov
We propose an adiabatic method for optimal phonon temperature estimation using trapped ions which can be operated beyond the Lamb-Dicke regime. The quantum sensing technique relies…
