Abstract
The use of ultrashort coherent light pulses to design and manipulate materials is a hot topic in condensed matter physics because it allows for control over a wide range of material properties as well as the observation of hidden broken-symmetry states. I talk about the role of first principles techniques in understanding ultrafast physical phenomena, with a particular emphasis on the inherent theoretical difficulties associated with the description of out-of-equilibrium systems. Finally, I discuss a novel approach to modeling insulators exposed to ultrafast pulses[1,2] as well as some real-world applications.
