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.

CECAM workshop Seeking synergy between dynamics and statistics for non-equilibrium quantum processes
Jun 6 – Jun 9 all-day

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.

IBER2017
Sep 12 – Sep 14 all-day

The next Joint Iberian Meeting on Atomic and Molecular Physics IBER 2017 will take place in Barcelona, Spain from September 12 to 14, 2017.

IBER is the biannual conference organised jointly by the Atomic and Molecular Physics Specialised Group (GEFAM) of the Spanish Royal Society of Physics and the Portuguese Society of Physics.

The main purpose of this series of IBER conferences is to bring together scientists of Iberian community dedicated to Atomic and Molecular Physics and related areas of to facilitate the interaction and exchange of knowledge between their research groups. Researchers and scientists from all over Europe and the world are invited to attend this conference and share knowledge. The conference will be structured in three days with plenary lectures, invited lectures, oral presentations and a poster session.
