Wignerâ€™s (2 n + 1) rule is proven for general total energy functionals, constructed from the expectation value of a linear Hamiltonian and a nonlinear functional of the electron density or of the first order density matrix. Such functionals are common in independent particle models, like...

We report results from simulations of charge and energy dynamics in poly(para-phenylenevinylene) (PPV) and PPV interacting with C60. The simulations were performed by solving the time-dependent SchrÃ¶dinger equation and the lattice equation of motion simultaneously and nonadiabatically. The...

The modulational instability (MI) of ion-acoustic waves (IAWs) in a two-component plasma is investigated in the context of the nonextensive statistics proposed by Tsallis [J. Stat. Phys. 52, 479 (1988)]. Using the reductive perturbation method, the nonlinear SchrÃ¶dinger equation (NLSE) which...
