Expert WG2 Meeting on Large Interstellar Molecules @ Lorentz Center
May 10 – May 13 all-day

The 3rd meeting organized in the framework of Working Group 2 of COST Action CM1204 (XUV/X-ray light and fast ions for ultrafast chemistry) will take place in Leiden (Netherlands) from May 11 to 13, 2015. It will be an expert meeting centered on Large Interstellar Molecules: “Energetic Processing of Large Interstellar Molecules”.

Three key questions will be addressed during the workshop:

  • Which experimental techniques do we need to develop to probe correlated electronic-vibrational dynamics in photo-activated molecules?
  • What is the functional role of non-equilibrium vibrational motion for energy and charge transport as well as energy storage in biomolecules? How are these specific molecular motions “selected”?
  • Do we have an appropriate theoretical framework to describe and understand these phenomena? Is the predictive power of the current theories enough to accurately predict dynamics and functionality?

FINANCIAL SUPPORT:
The participation of a limited number of XLIC participants and speakers will be supported with the Action budget. Participants entitled for reimbursement should have been informally notified about their status.

By the end of March, all participants will receive an official invitation to the meeting confirming their eligibility status and highligting some of the COST rules for reimbursement which should be carefully examined before incurring any expense in:

Since the budget allocated for the meeting is limited, it is highly reccomended keeping the claims for meals and accomodation at the actual level of expensiture during the meeting. Nevertheless. in compliance with COST rules, this subsistence expenses will be reimbursed on the basis of flat rates (no need to show invoices). The applicable flat rates for this meeting, as approved by XLIC Management Committee, are 100 EUR for accommodation and 0 EUR for meals.

For travel expenses actual costs can be claimed on the basis of the receipts provided. (Any restriction applying to travel expenses will be notified to each participant entitled for reimbursement)

IMPORTANT: Participants selected for reimbursement are kindly asked to keep their expenses as low as possible to ensure a wide distribution of the Action budget.

The submission of claims shall be done after the meeting, but, for any non-regular expense or doubt you may have, please, better ask in advance (info@xlic.eu). E.g. fligths departure/arrivals from/to places other than where the eligible participant is working/residing, extra meals, nights, taxi expenses, etc. shall not be reimbursed if permission is not requested before the meeting.

CECAM School: Quantum and Mixed Quantum Classical Dynamics in photochemistry @ CECAM HQ
May 14 – May 18 all-day
CECAM School: Quantum and Mixed Quantum Classical Dynamics in photochemistry @ CECAM HQ | Lausanne | Vaud | Switzerland

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.

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.
