Bilobran-Angelo entropic distance in coherently and incoherently-driven high-harmonic generation — •Arlans Juan Smokovicz de Lara, Ulf Saalmann, and Jan-Michael Rost — Max-Planck-Institute für Physik komplexer Systeme

Since its discovery, high harmonic generation (HHG), as a process non-linear in the number of photons, has been realized with intense classical light. Recently, progress has been made towards a quantum mechanical description of the harmonic modes, enabling the creation of non-classical intense light pulses [1], which promises new quantum effects in the interaction with matter. In particular, thanks to said quantum description of the modes, we can now treat interesting quantum mechanical properties, for instance the realism of measurements in the context of the Bilobran-Angelo entropic distance [2]. We will present first results of said quantity in the contexts of coherently-driven [3] and incoherently-driven [4] in HHG in pristine graphene.
