Quantum synchronization has been a central topic in quantum nonlinear dynamics. Despite
the rapid development in this field, very few have studied how to efficiently boost …

We develop a general theoretical framework of semiclassical phase reduction for analyzing
synchronization of quantum limit-cycle oscillators. The dynamics of quantum dissipative …

Optimal entrainment of a quantum nonlinear oscillator to a periodically modulated weak
harmonic drive is studied in the semiclassical regime. By using the semiclassical phase …

Driven classical self-sustained oscillators have been studied extensively in the context of
synchronization. Using the master equation, this work considers the classically driven …

Large clouds of atoms in a magneto-optical trap (MOT) are known to exhibit spatiotemporal
instabilities when the frequency of the trap** lasers comes close to the atomic resonance …

Figure 1: Roulet and Bruder analyzed phase-space plots for two-level (left) and three-level
(right) systems driven by an external, oscillating field. A stable limit cycle—indicated in the …

Synchronization in pulse-coupled oscillators has been broadly studied under different
perspectives. We present a game with simple rules to describe synchronization in such …

Some nonlinear radiations such as superfluorescence can be understood as cooperative
effects between atoms. We regard cooperative radiations as a manifested effect secondary …

This paper presents a novel method for achieving parametric excitation in an optical
polarization-modulated magneto-optical trap for a two-level atom. The proposed method has …

In this Thesis, we study the fundamental aspects of self-oscillating atomic clouds in a large,
balanced Magneto-Optical Trap (MOT). These instabilities bear analogies with astrophysical …
