 na-WiSe2025.pdf).</p> <p><strong>Abstract</strong>: Modeling the linear a
 nd nonlinear optical response of complex systems from first principles is 
 one of the most challenging tasks in theoretical materials science. How is
  it possible to predict the outcome of the light-matter interaction for a 
 system of 1023 particles\, only from the basic laws of quantum mechanics a
 nd electrodynamics? In this colloquium\, we will take a journey into class
 ic and innovative approaches in atomistic materials modelling\, discussing
  capability and actual limits of computational physics. In particular\, a 
 novel approach based on the calculation of the dynamical polarization is i
 ntroduced\, which is applied to cutting-edge research topics at the TU Dre
 sden. The presented methods allow both to understand the outcome of experi
 mental investigations as well as to identify the relationships between com
 position\, morphology and the macroscopic material properties. In turn\, t
 his paves the way for computer-supported material design\, inspiring the r
 ealization of real structures with tailored properties.</p> <p><strong>Sho
 rt bio</strong>: Simone Sanna is professor for theoretical physics at the
  Justus Liebig University in Giessen\, where he leads the research group t
 heoretical solid-state spectroscopy. With his team\, he performs quantum m
 echanical simulations to predict the physical properties of complex materi
 al systems on the basis of their microscopic structure. Besides developing
  first-principles computational approaches to model spectroscopic signatur
 es\, AI based models are applied for the interpretation of imaging spectro
 scopy results. Ferroelectric oxides\, optically nonlinear molecular cluste
 rs and on surface molecular synthesis are in the focus of the research.</p
