Energy exchange between coupled mechanical oscillators: linear regimes
(IOP Publishing, 2018-09)
Nonlinear mechanisms are frequently invoked to explain unexpected observations during processes of energy exchange in mechanical systems. However, whether the same phenomena could be observed in a purely linear system is ...
Time evolution of an atomic system in the presence of a time dependent electric field
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Coherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
(2000-08-01)
The atomic tunneling between two tunnel-coupled Bose-Einstein condensates (BECs) in a double-well time-dependent trap was studied. For the slowly varying trap, synchronization of oscillations of the trap with oscillations ...

Carbon monoxide oxidation over platinum: Stable, oscillatory and quasi-chaotic regimes
(1998-08-15)
We model the heterogeneously catalyzed oxidation of CO over a Pt surface. A phase diagram analysis is used to probe the several steady state regimes and their stability. We incorporate an experimentally observed 'slow' ...
Instabilities of spin torque driven auto-oscillations of a ferromagnetic disk magnetized in plane
(Amer Physical Soc., 2016)
The stability of the magnetization auto-oscillations of the ferromagnetic free layer of a cylindrical nanopillar structure is studied theoretically using a classical Hamiltonian formalism for weakly interacting nonlinear ...

Determination of the critical coupling for oscillators in a ring
(American Institute of Physics (AIP), 2009-09-01)
We study a model of coupled oscillators with bidirectional first nearest neighbors coupling with periodic boundary conditions. We show that a stable phase-locked solution is decided by the oscillators at the borders between ...
Nonlinearity-induced synchronization enhancement in micromechanical oscillators
(American Physical Society, 2015-01)
An autonomous oscillator synchronizes to an external harmonic force only when the forcing frequency lies within a certain interval - known as the synchronization range - around the oscillator's natural frequency. Under ...
