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 XLIC WG1&WG2 Expert Meeting “From Ultrafast to Ultraslow Dynamics in Molecules and Clusters” will be held in the Weizmann Institute of Science Israel , from 23th to 25th January 2017.The Meeting is jointly organized by the Local organizing committee, the team of the conference unit of the Weizmann Institute and COST CM1204 Action (XLIC).
The workshop participation is open to everybody.
Scope and Program of the Meeting
Dynamical processes in molecular and cluster systems play an important role in different disciplines of research including atmospheric and interstellar chemistry, biology, nano-science and more. It is appealing to classify different types of dynamics according to their time scale – from attosecond electronic dynamics, femtosecond and picosecond ro-vibrational motion up to typical nanosecond times of spontaneous radiative processes. However, even in small clusters and biomolecules, coupling of many degree’s of freedom can lead to ultra-slow dynamics extending up to millisecond times.
In recent years, experimental techniques for studying these different dynamics have considerably advanced – from the development of ultrafast light sources, including high-order harmonic generation and free electron laser X-ray facilities, as well as highly controlled ion traps and ion storage rings that allow following a slow evolving time evolution of isolated molecular and cluster ions. On the theoretical side, quantum mechanical calculations provide insight regarding short time scales, while statistical models can describe long time dynamics on the ensemble level.
These communities have developed in parallel and often with little interaction with each-other. The goal of this workshop will be to bridge the gap between the different communities towards a full understanding of molecular and cluster dynamics. For example, it will be valuable to understand the role of initial ultrafast electronic and vibrational rearrangement of an isolated system on its slow decay by statistical fragmentation. Does ultrafast dynamics leading to internal conversion influence delayed recurrent fluorescence events? What is the importance of the coherent vibrational motion for long term processes and spectroscopic probes of isolated interstellar environments or biomolecular systems?
We aim at achieving this goal by bringing together leading experts from the different fields: including atto-second science, femto-chemistry, action spectroscopy, ion storage devices, time-dependent quantum mechanics and statistical physics – in order to promote a common language and shared goals. In particular, participants will be asked to highlight the scientific goals and challenges of each field to promote collaborative efforts. We hope that this conference will generate long term collaborations that will advance our understanding of molecular and cluster science across the different time scales.

The CECAM workshop Seeking synergy between dynamics and statistics for non-equilibrium quantum processes will be held in Paris in June 6th-9th.
One of the major difficulties in achieving an accurate theoretical descriptions of non-equilibrium processes in quantum mechanical systems is framed by the desire to provide a representation of the system of interest that is as realistic as possible, in a manner that is computationally tractable. The coupling of electronic and nuclear motion involving excited states, the quantum nature of the nuclear degrees of freedom, and the application of time-dependent driving forces, are just few examples of the effects that must be addressed in order to simulate these processes. Each of these effects poses unique challenges to theoretical progress. A number of exact and approximate quantum dynamics techniques are being developed and refined in order to provide algorithms that respond to the demand for a balance between computational efficiency and physical accuracy. Currently available techniques are typically based upon two different, but equivalent, formulations of many-body quantum mechanics, the wave function approach or the density matrix picture.
The proposed workshop aims to bring together the two principal molecular quantum dynamics communities (wave-function methods and density matrix approaches). The scope is threefold, (i) to identify and explore common goals and obstacles, (ii) help in fostering new ideas to connect these approaches, and bridge the apparent gap between approximate dynamical and statistical descriptions, (iii) identify possible routes to extend dynamics approaches to the domain of statistics.
At the workshop, experts are asked to uncover the fundamental details of the methods in pedagogical lectures. These lectures will be followed by extensive discussions, during which contributed speakers and participants are welcome to put forth some of their doubts and problems in the relation between dynamics and statistics.

Although computer simulation of the electronic structure and properties of solids began decades ago, only recently the solid state methodologies have become sufficiently reliable that their application has resulted in an increasingly important impact on solid state chemistry and physics. , While a large number of course and tutorials already exists, they are mainly focused on audiences with strong background on solid state physics, and usually devoted to some particular electronic structure code. Far more unusual are the courses designed to teach the solid-state techniques to chemists, thus contributing to eliminate the cultural barriers that still exist between both groups. This school is primarily targeted to PhD students and post docs who are interested or are starting to learning about the application theory methods and techniques to the study of the physics and chemistry of the solid state.
The level of this tutorial corresponds to master or doctorate students in areas of physics and chemistry. After two initial days where the fundamentals of theory of the treatment of the electronic structure of solids will be presented to the students, the remaining of the tutorial will be devoted to the examination of specific and hot areas like characterization of chemical bonding in solids and relationship to macroscopic properties, structure and reactivity at solid surfaces, including layered systems and highly correlated oxides, and magnetic properties. The afternoons will be dedicated to practical hand-on tutorials. Several computational codes are actively being developed, capable of simulating molecules, pure and defective crystals, surface and transport properties, and reactive processes in the bulk and interfaces. Getting familiar with the different codes and their possibilities requires an adequate training that merges theory and practice in substantial amounts.
