With the advent of nanoscale physics and ultrafast lasers it is now possible to directly probe real-time the correlated motion of electrons and nuclei in excited quantum states. In addition, the intensity and profile of the laser field can be tuned to control and manipulate the opto-electronic properties of a wide range of molecules and materials. All these progresses have opened new fields of research like, e.g., molecular transport, nanoelectronics, atto-physics/chemistry, nonequilibrium phase transitions, ultracold atomic gases, optimal control theory, etc.
Experiments are usually carried on large molecules, biological systems and nanostructures whose peculiar dynamical properties are inevitably linked to their atomistic structure. Thus, an ab-initio, time-dependent and quantum-mechanical approach is required for reliable calculations. The aim of this workshop was to gather together many of the most prominent theoretical and experimental scientists to advance our fundamental understanding of matter under extreme nonequilibrium conditions. Particular emphasis was given to many-body methods like Nonequilibrium Green’s Functions Theory (NEGF) and how to combine NEGF with ab initio methods like Density Functional Theory.

CECAM-HQ-EPFL, Lausanne, Switzerland, 26-28 November 2018
Organizers: Jerome Jackson and Martin Lüders, STFC Daresbury Laboratory, UK
32 speakers and participants took part in the Psi-k, CCP-magnetism and CECAM financed Workshop on the subject of Ab Initio Spin Modelling, which was held at CECAM-HQ, Lausanne, between 26—28 November 2018. The format of the event was designed to foster discussion between groups working on diverse problems in the ab initio treatment of magnetism in solids. Talks of approximately one hour by the invited speakers were interspaced with much lively and enjoyable discussion. The long talks were intended to allow detailed, in depth presentations and this was indeed the outcome. The speakers represented work in quite different methods with electronic structure (e.g., from fully relativistic KKR to perturbation theory based on pseudopotentials/plane waves) – this seemed, if anything, to motivate and promote questions and active involvement by all the participants. Productive discussion also took place during the poster sessions where the quality of the poster presentations was extremely high.
