text: The transverse dynamic spin susceptibility is a correlation function that
yields exact information about spin excitations in systems with a collinear magnetic
ground state, including collective spin-wave modes. In an ab initio context, it
may be calculated within many-body perturbation theory or time-dependent density-functional
theory, but the quantitative accuracy is currently limited by the available functionals
for exchange and correlation in dynamically evolving systems. To circumvent this
limitation, the spin susceptibility is here alternatively formulated as the solution
of an initial-value problem. In this way, the challenge of accurately describing
exchange and correlation in many-electron systems is shifted to the stationary
initial state, which is much better understood. The proposed scheme further requires
the choice of an auxiliary basis set, which determines the speed of convergence
but always allows systematic convergence in practical implementations.
