Quantum versus classical chirps in a Rydberg atom
Tsafrir Armon, Lazar Friedland
The interplay between quantum-mechanical and classical evolutions in a chirped driven Rydberg atom is discussed. It is shown that the system allows two continuing resonant excitati…
Quantum versus classical effects in the chirped-drive discrete nonlinear Schrodinger equation
Tsafrir Armon, Lazar Friedland
A chirped parametrically driven discrete nonlinear Schrodinger equation is discussed. It is shown that the system allows two resonant excitation mechanisms, i.e., successive two-le…
Quantum versus classical dynamics in the optical centrifuge
Tsafrir Armon, Lazar Friedland
The interplay between classical and quantum mechanical evolution in the optical centrifuge (OC) is discussed. The analysis is based on the quantum mechanical formalism starting fro…
Chirped-Frequency Excitation of Gravitationally Bound Ultracold Neutrons
Giovanni Manfredi, Omar Morandi, Lazar Friedland +2
Ultracold neutrons confined in the Earth's gravitational field display quantized energy levels that have been observed for over a decade. In recent resonance spectroscopy experimen…
Two-photon ladder climbing and transition to autoresonance in a chirped oscillator
Ido Barth, Lazar Friedland
The two-photon ladder climbing (successive two-photon Landau-Zener-type transitions) in a chirped quantum nonlinear oscillator and its classical limit (subharmonic autoresonance) a…
Quantum and Classical Chirps in an Anharmonic Oscillator
Yoni Shalibo, Ya'ara Rofe, Ido Barth +4
We measure the state dynamics of a tunable anharmonic quantum system, the Josephson phase circuit, under the excitation of a frequency-chirped drive. At small anharmonicity, the st…
