the International Science at FELs 2014 @ Paul Scherrer Institute
Sep 14 – Sep 17 all-day

The International Science at FELs 2014 conference, organised under the auspices of the “Collaboration of European FEL and SPS Facilities”,  will take place at the Paul Scherrer Institute in Villigen, Switzerland, from the 15th to the 17th of September 2014. The conference highlights recent science achievements and new developments in the expanding field of free electron lasers. It covers applications in condensed matter research, biology, chemistry, matter under extreme conditions, atomic and molecular systems as well as theory.

Dedicated introductory lectures for students are offered at the start of the conference. To encourage student participation, student grants have been provided by several sponsors (student support application deadline is on the 30th of June 2014).

Spectroscopy Lectures :: theory and codes @ CECAM-HQ-EPFL
Jun 18 – Jun 19 all-day

The CECAM School on: “Theoretical Spectroscopy Lectures: theory and codes” reaches the 6th edition and takes place from 18th to 22th of May, 2015 at the CECAM-HQ-EPFL, Lausanne, Switzerland.

Electronic excitations are probed by experimental techniques such as optical absorption, EELS and photo-emission (direct or inverse). From the theory point of view, excitations and excited state properties are out of the reach of density-functional theory (DFT), which is a ground-state theory. In the last twenty years other ab-initio theories and frameworks, which are able to describe electronic excitations and spectroscopy, have become more and more used: time-dependent density-functional theory (TDDFT) and many-body perturbation theory (MBPT) or Green’s function theory (GW approximation and Bethe-Salpeter equation BSE). In fact, computational solutions and codes have been developed in order to implement these theories and to provide tools to calculate excited state  properties.The present school focuses on these points, covering theoretical, practical, and also numerical aspects of TDDFT and MBPT, and codes implementing them (ABINIT, DP, EXC).

The presentation of the theory will be followed by practical classes and hands-on  tutorials. At the end of the school, students will have sufficient working knowledge to  pursue their projects at their home institution. The participants are expected to have a fair knowledge of DFT prior to the school (see Ref. 1, given in the school’s website) and to be familiar with one plane-wave pseudopotential based software.
Indeed, although at the beginning of the school, we will make sure that the DFT level of all participants is enough in this respect and provide the needed complementary  information and training, the purpose of the school is to go beyond DFT, with hands-on exercices based on plane-wave implementations.

The deadline for application is on 15 April 2015, but giving the limited number of places (around 25) many applications will be considered even before the deadline. Especially student candidates coming from outside EU are encouraged to register soon: an answer to them will be given as soon as possible for VISA and traveling purposes.
