Transition to super-diffusive transport in turbulent plasmas
Matteo Stanzani, Filippo Arlotti, Guido Ciraolo +2
We investigate the motion of charged particles in a turbulent electrostatic potential using guiding-center theory. By increasing the Larmor radius, the dynamics exhibit close-to-ba…
Nonlinear dynamics of molecular superrotors
Cristel Chandre, J. Pablo Salas
We consider a diatomic molecule driven by a linearly polarized laser pulse with a polarization axis rotating with a constant acceleration. This setup is referred to as optical cent…
Hamiltonian formulation and symplectic split-operator schemes for time-dependent density-functional-theory equations of electron dynamics in molecules
Francois Mauger, Cristel Chandre, Mette B. Gaarde +2
We revisit Kohn-Sham time-dependent density-functional theory (TDDFT) equations and show that they derive from a canonical Hamiltonian formalism. We use this geometric description…
Four-field Hamiltonian fluid closures of the one-dimensional Vlasov-Poisson equation
Cristel Chandre, Bradley A Shadwick
We consider a reduced dynamics for the first four fluid moments of the onedimensional Vlasov-Poisson equation, namely, the fluid density, fluid velocity, pressure and heat flux. Th…
Classical Nambu brackets in higher dimensions
Cristel Chandre, Atsushi Horikoshi
We consider n-linear Nambu brackets in dimension N higher than n. Starting from a Hamiltonian system with a Poisson bracket and K Casimir invariants defined in the phase space of d…
Numerical computation of critical surfaces for the breakup of invariant tori in Hamiltonian systems
Adrian P. Bustamante, Cristel Chandre
We compute the critical surface for the existence of invariant tori of a family of Hamiltonian systems with two and three degrees of freedom. We use and compare two methods to comp…
