Husimi-Wigner representation of chaotic eigenstates
Fabricio Toscano, Anatole Kenfack, Andre R. R. Carvalho +2
Just as a coherent state may be considered as a quantum point, its restriction to a factor space of the full Hilbert space can be interpreted as a quantum plane. The overlap of suc…
Bifurcations and sudden current change in ensembles of classically chaotic ratchets
Anatole Kenfack, Sean Sweetnam, Arjendu K. Pattanayak
In \prl 84, 258 (2000), Mateos conjectured that current reversal in a classical deterministic ratchet is associated with bifurcations from chaotic to periodic regimes. This is base…
Bifurcation and Chaos in Coupled Periodically Forced Non-identical Duffing Oscillators
U. E. Vincent, A. Kenfack
We study the bifurcations and the chaotic behaviour of a periodically forced double-well Duffing oscillator coupled to a single-well Duffing oscillator. Using the amplitude and the…
Bifurcation and Chaos in Coupled Ratchets exhibiting Synchronized Dynamics
U. E. Vincent, A. Kenfack, A. N. Njah +1
The bifurcation and chaotic behaviour of unidirectionally coupled deterministic ratchets is studied as a function of the driving force amplitude () and frequency (). A classi…
