Abstract
The generation and dynamics of self-localized excitations in polyacety lene following a resonant fs pulse after introduction of some nucleati on centres are calculated using the Su-Schrieffer-Heeger model. We obt ain and investigate soliton pairs with an oscillating dipole moment an d localized breathers. Furthermore, the linear photoinduced absorption is calculated and discussed in random phase approximation using the i nstantaneous eigenstates.
