Excitations in time-dependent density-functional theory.

Physical review letters

Appel H, Gross EK, Burke K.
PMID: 12570418
Phys Rev Lett. 2003 Jan 31;90(4):043005. doi: 10.1103/PhysRevLett.90.043005. Epub 2003 Jan 31.

An approximate solution to the time-dependent density-functional theory response equations for finite systems is developed, yielding corrections to the single-pole approximation. These explain why allowed Kohn-Sham transition frequencies and oscillator strengths are usually good approximations to the true values,...

Dynamical properties of chemical systems near Hopf bifurcation points.

Chaos (Woodbury, N.Y.)

Ipsen M, Schreiber I.
PMID: 12779429
Chaos. 2000 Dec;10(4):791-802. doi: 10.1063/1.1311980.

In this paper, we numerically investigate local properties of dynamical systems close to a Hopf bifurcation instability. We focus on chemical systems and present an approach based on the theory of normal forms for determining numerical estimates of the...

Systematic derivation of amplitude equations and normal forms for dynamical systems.

Chaos (Woodbury, N.Y.)

Ipsen M, Hynne F, Sorensen PG.
PMID: 12779791
Chaos. 1998 Dec;8(4):834-852. doi: 10.1063/1.166370.

We present a systematic approach to deriving normal forms and related amplitude equations for flows and discrete dynamics on the center manifold of a dynamical system at local bifurcations and unfoldings of these. We derive a general, explicit recurrence...
