“…It was extensively studied in the context of relativistic particle acceleration: in the 40-ies by McMillan [5], Veksler [6] and Bohm and Foldy [7,8], and more recently [9][10][11][12]. Additional applications include a quasiclassical scheme of excitation of atoms [13] and molecules [14], excitation of nonlinear waves [15,16], solitons [17,18], vortices [19,20] and other collective modes [21] in fluids and plasmas, an autoresonant mechanism of transition to chaos in Hamiltonian systems [22,23], etc.…”

We investigate parametric autoresonance: a persisting phase locking which occurs when the driving frequency of a parametrically excited nonlinear oscillator slowly varies with time. In this regime, the resonant excitation is continuous and unarrested by the oscillator nonlinearity. The system has three characteristic time scales, the fastest one corresponding to the natural frequency of the oscillator. We perform averaging over the fastest time scale and analyze the reduced set of equations analytically and numerically. Analytical results are obtained by exploiting the scale separation between the two remaining time scales which enables one to use the adiabatic invariant of the perturbed nonlinear motion.

“…Autoresonant excitation has been observed in a wide variety of environments, including atomic systems [18,19], plasmas [20,21], fluids [22], and semiconductor quantum wells [23]. Some authors also noticed the beneficial effect of a chirped pulse on the magnetization dynamics in a nanoparticle [24][25][26], but lacked the analytical tools provided by the autoresonance theory.…”

The ability to control the magnetization switching in nanoscale devices is a crucial step for the development of fast and reliable techniques to store and process information. Here we show that the switching dynamics can be controlled efficiently using a microwave field with slowly varying frequency (autoresonance). This technique allowed us to reduce the applied field by more than 30% compared to competing approaches, with no need to fine-tune the field parameters. For a linear chain of nanoparticles the effect is even more dramatic, as the dipolar interactions tend to cancel out the effect of the temperature. Simultaneous switching of all the magnetic moments can thus be efficiently triggered on a nanosecond timescale. * Electronic address: manfredi@unistra.fr

“…This permits the simple and unambiguous realization of Trojan wave packets. Furthermore, we demonstrate that these Trojan wave packets are remarkably robust and can be adiabatically transported [15][16][17] to much higher n $ 600, while preserving their circularity and localization, by chirping the frequency of the drive field. Creation of such states moves measurements a step closer to the macroscopic limit facilitating studies of classical-quantum correspondence [18].…”

Nondispersive localized Trojan wave packets with n i $ 305 moving in near-circular Bohr-like orbits are created and transported to localized near-circular Trojan states of higher n, n f $ 600, by driving with a linearly polarized sinusoidal electric field whose period is slowly increased. The protocol is remarkably efficient with over 80% of the initial atoms being transferred to the higher n states, a result confirmed by classical trajectory Monte Carlo simulations.
