“…Thus, trapped ions are an ideal platform for simulating quantum oscillator models. This extends recent work on nonlinear dynamics with trapped ions into the quantum regime [23][24][25][26][27][28][29][30].…”

Quantum Synchronization of Quantum van der Pol Oscillators with Trapped Ions

The van der Pol oscillator is the prototypical self-sustained oscillator and has been used to model nonlinear behavior in biological and other classical processes. We investigate how quantum fluctuations affect phase locking of one or many van der Pol oscillators. We find that phase locking is much more robust in the quantum model than in the equivalent classical model. Trapped-ion experiments are ideally suited to simulate van der Pol oscillators in the quantum regime via sideband heating and cooling of motional modes. We provide realistic experimental parameters for 171Yb+ achievable with current technology.

“…As is well known, in an optical laser, Q-switching can be used to modulate the quality factor of a laser, to obtain optical pulses with high peak power and repetition rate [36][37][38][39][40]. For mechanical analogs, pulsed phonon lasing has been realized in trapped ions [41]. Q-switching and pulsed phonon transfer in a levitated nanoparticle, as in trapped ionic systems, requires a feasible method for coupling two motional modes [41].…”

We theoretically investigate the active Q-switching of an optical tweezer phonon laser [R. M. Pettit et al., Nature Photonics 13, 402 (2019)] operating in a coupled-mode configuration. One of the modes is lasing and outcouples to the second mode. The coupling is induced via asymmetric modulation of the trap potential in the transverse plane of the trapped nanoparticle. We show that a time-modulated coherent coupling between two transverse modes of oscillation of an optically levitated nanoparticle holds the key to coherent pulsed phonon transfer between them. Our analytical and numerical results on the position dynamics, phonon dynamics as well as second order coherence confirms pulsed phonon lasing transfer between the transverse modes. Our work on Q-switched operation of the optical tweezer phonon laser enhances understanding of the analogies between optical and mechanical lasers, and is relevant to levitated phonon transport, acoustic imaging, sensing and information processing technologies.

“…[2] In contrast, if they are driven away from the equilibrium positions to the nonlinear regime, the ions will suffer from motional heating and thereby be instable due to experiencing high-order multipole potentials, such as hexapole and octopole potentials. [1] However, if controllable, the nonlinearity of the trapped ion can be useful, for example, to achieve trapped-ion phononic lasing [3][4][5] and to work for resonance detection in trapped-ion mass spectrometry. [6,7] Moreover, a single trapped ion behaves like a Duffing oscillator when driven to the nonlinear regime, [8] which may be used for ultraprecision measurement beyond the quantum standard limit.…”

Stochastic resonance is a counterintuitive phenomenon amplifying the weak periodic signal by application of external noise. We demonstrate the enhancement of a weak periodic signal by stochastic resonance in a trapped-ion oscillator when the oscillator is excited to the nonlinear regime and subject to an appropriate noise. Under the full control of the radio-frequency drive voltage, this amplification originates from the nonlinearity due to asymmetry of the trapping potential, which can be described by a forced Duffing oscillator model. Our scheme and results provide an interesting possibility to make use of controllable nonlinearity in the trapped ion, and pave the way toward a practical atomic sensor for sensitively detecting weak periodic signals from real noisy environment.
