Linear and non-linear responses in pump-probe spectroscopy — •Tanja Dimitrov¹, Heiko Appel¹, and Angel Rubio^{1, 2} — ¹Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany — ²NanoBio Spectroscopy group and ETSF, Universidad del País Vasco, San Sebastián, Spain

In this work, we investigate the time-dependent dipole response of molecular systems for pump probe laser experiments. We compare the response of widely used approximate adiabatic functionals in time-dependent density functional theory to the exact solution of the time-dependent Schrödinger equation for realistic model systems. In particular, we focus on the role of memory effects and the corresponding signature in the optical absorption spectra.
