PRIN: PROGETTI DI RICERCA DI RILEVANTE INTERESSE NAZIONALE - Bando 2015 Prot. 2015CL3APH
The ambition of project NEWLI is to obtain significant advances in the study of transient and excited states induced in condensed matter by the absorption of light, exploiting new opportunities in photon and electron based spectroscopy; the focus is on metal and metal oxide nanostructures. The description of light absorption is often limited to a description of ground and final states in the one electron approximation. Instead, a many body description and a physical/chemical understanding of the intermediate states is expected to be of considerable fundamental and applicative importance: rather than knowing simply the outcome of light absorption we seek to understand *how* and *why* it occurred. This is the time to exploit the new experimental tools which are now available: free electron lasers emitting brilliant fs pulses of EUV/X-ray radiation, improved and full use of the time structure of synchrotron radiation sources, continuing developments in optical spectroscopy with time resolution and electron coincidence methods. In parallel, a combination of non-equilibrium Green's functions theory and ab-initio methods based on Density Functional Theory promise to allow simulation and prediction of processes and experiments. The project is organized in four science driven workpackages which correspond to stimulating scientific themes: i) plasmon dynamics, ii) core - hole dynamics, iii) energy and charge transfer in metal / metal oxide nanostructures and iv) non - linear and fs time-scale photon - matter interactions. The proponents are based at Universities, at CNR research institutes and/or major large scale photon science facilities. These groups have all previously successfully collaborated and have a strong track record in training of students and performing advanced experiments and/or theoretical simulations.

Abstract
The ambition of project NEWLI is to obtain significant advances in the study of transient and excited states induced in condensed matter by the absorption of light, exploiting new opportunities in photon and electron based spectroscopy; the focus is on metal and metal oxide nanostructures. The description of light absorption is often limited to a description of ground and final states in the one electron approximation. Instead, a many body description and a physical/chemical understanding of the intermediate states is expected to be of considerable fundamental and applicative importance: rather than knowing simply the outcome of light absorption we seek to understand *how* and *why* it occurred. This is the time to exploit the new experimental tools which are now available: free electron lasers emitting brilliant fs pulses of EUV/X-ray radiation, improved and full use of the time structure of synchrotron radiation sources, continuing developments in optical spectroscopy with time resolution and electron coincidence methods. In parallel, a combination of non-equilibrium Green's functions theory and ab-initio methods based on Density Functional Theory promise to allow simulation and prediction of processes and experiments. The project is organized in four science driven workpackages which correspond to stimulating scientific themes: i) plasmon dynamics, ii) core - hole dynamics, iii) energy and charge transfer in metal / metal oxide nanostructures and iv) non - linear and fs time-scale photon - matter interactions. The proponents are based at Universities, at CNR research institutes and/or major large scale photon science facilities. These groups have all previously successfully collaborated and have a strong track record in training of students and performing advanced experiments and/or theoretical simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
