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.

The following block will focus on mono- and multi-configurational electronic structure methods for the description of excited states. The last block will cover dynamics methodologies. (see description below). The school will end with a comprehensive overview (2 hours) of state-of-the-art applications, limitations, suitabilities, future perspectives and challenges of the different static and dynamical approaches described in the school.

Photochemical reactions have tremendous scientific importance, ranging from photosynthesis to atmospheric reactions, and technologies such as sensors or displays. Due to the intrinsic complexity of photochemical reactions, they remain the least understood type of chemical process. Nonadiabatic dynamics, ultrafast time-scales, quantum effects and conical intersections are known to be important, but a detailed comprehension remains elusive. However, new experimental techniques capable of monitoring photochemical processes in unprecedented detail are appearing. This includes the development of intense-laser techniques, the construction of free-electron lasers such as the XFEL in Europe and the LCLS in the USA, new sources of pulsed electrons, advanced detection techniques, and important advances in theoretical modelling of quantum dynamics. Many of these techniques are developed by research communities not traditionally concerned with photochemistry, but provide an opportunity to shed new light on photochemical dynamics.
The themes for the meeting are:
Electronic and non-adiabatic dynamics
Attosecond processes and X-ray spectroscopy
Vibrational and condensed phase dynamics
Deadline for abstract submission: Dec. 14, 2015
Confirmed speakers include:
Prof. Dan Neumark (Berkeley), Prof. Dwayne Miller (Hamburg), Prof. Fernando Martin (Madrid), Prof. Shaul Mukamel (Irvine), Prof. Albert Stolow (Ottawa), Dr. Yann Mairesse (Bordeaux), Dr. Mike Minitti (SLAC), Prof. Artem Rudenko (Kansas), Prof. Andrew Orr-Ewing (Bristol), Dr. Junko Yano (Lawrence-Berkeley)

The International school on “The Frontiers of Attosecond and Ultrafast X-ray Science” will be held from 19th to 28th March 2017 in Erice, Sicily, Italy.
The primary objective of this new school is to educate the next generation of scientists who will impact the future of attosecond and ultrafast x-ray science. We anticipate that the school will meet on a regular basis every two years and become a foundation for the ultrafast community. Consequently, the main topics of the course are the following: (i) attosecond science and technology, devoted to the generation and application of attosecond pulses to the investigation of electronic dynamics in atoms, molecules, nanostructures and condensed phases; (ii) fundamentals, methods and applications of free electron lasers, synchrotron radiation, ion collisions in atomic and molecular science. Lectures will cover current developments in theory and experiments but are also intended to give the basics of the field.
Please note that, PhD students and post-docs willing to attend the school can apply for scholarships (deadline 30 January 2017). For more details see: http://www.erice-attosecond.it/registration
The school co-organised by XLIC COST Action and sponsored by Politecnico di Milano, Italian Ministry of Education and Scientific Research, Sicilian Regional Parliament, ELI-ALPS and Ettore Majorana Foundation and Centre for Scientific Culture.

Photoinitiated processes are not only important for understanding natural phenomena but they also play an undeniable role in the booming fields of renewable energy, material design and medicine. Excited state processes have traditionally been explained from a static point of view, delivering in some cases a biased, incorrect or even incomplete description of the former. The simulation of the dynamics of such processes is therefore fundamental for the quest to understand the chemical and physical mechanisms.
The purpose of this school is to introduce its participants to state-of-the-art methodologies for the simulation of the dynamics of processes in the excited state, following the evolution in time of photoinitiated reactions, one of the priority topics of this call.
The school will be focused in simulating the dynamics of complex molecules. Electronic ab initio or TD-DFT methods would be sketched for obtaining the electronic wavefunctions or densities, that would be afterwards quantum-mechanically propagated. Moreover, several approaches for the treatment of the nuclei will be also provided, from full quantum dynamics to mixed quantum-classical dynamics.
The course is directed at PhD students, and young researchers, beginners in the field, working in theoretical chemistry and molecular physics.
