Diffusion for Hamiltonian Maps with Frequency Modulation
نویسنده
چکیده
The action diiusion of an area preserving map, whose linear frequency is stochas-tically perturbed, is described by a Fokker-Planck equation with a coeecient obtained from the normal form. The local properties are investigated on the standard map and the angle is shown to have a fast relaxation. A comparison is made with the diiusive process determined by a slow periodic modulation of the frequency.

Diffusion in Stochastically and Periodically Modulated Hamiltonian Systems
We consider an area preserving map whose linear frequency is stochastically perturbed. When no low order resonances are present a Fokker-Planck equation for the action diiusion is written and its solution agrees with the simulation of the process. The key point is the description of the map with an interpolating hamiltonian for which the action diiusion coeecient can be analytically computed. W...
متن کاملElectron hopping between localized states: A simulation of the finite-temperature Anderson problem using density functional methods
We present a simulation of the dynamics of electron packets in a-Si at finite temperature by integrating the time dependent Schrödinger equation using a first-principles Hamiltonian in conjunction with thermal simulation of ion dynamics. The mechanism of diffusion of localized states is thermally modulated resonant mixing with extended or localized states adjacent in energy and real space. For ...
متن کاملApplication of the GALI Method to Localization Dynamics in Nonlinear Systems
We investigate localization phenomena and stability properties of quasiperiodic oscillations in N degree of freedom Hamiltonian systems and N coupled symplectic maps. In particular, we study an example of a parametrically driven Hamiltonian lattice with only quartic coupling terms and a system of N coupled standard maps. We explore their dynamics using the Generalized Alignment Index (GALI), wh...

متن کاملOn the $k$-ary Moment Map
The moment map is a mathematical expression of the concept of the conservation associated with the symmetries of a Hamiltonian system. The abstract moment map is defined from G-manifold M to dual Lie algebra of G. We will interested study maps from G-manifold M to spaces that are more general than dual Lie algebra of G. These maps help us to reduce the dimension of a manifold much more.
