[vip-all] Vi får nye kontoplaner på mandag
by Ruth Laursen 19 May '09

19 May '09

Kære alle På mandag overgår hele Universitetet til ny kontoplan, som I skal bruge herefter. De nye kontoplaner for IFA og ISA bliver lagt på vores hjemmeside allerførst i næste uge. Jeg sender mail, når de er klar.

[vip-all] LECTURES ON ENERGY - TODAY

LECTURES ON ENERGY - TODAY!!!! Title: Towards a carbon free energy supply - scenarios for the future Danish Energy System Speaker: Anders Bavnhøj Hansen Energinet.dk Time: Tuesday, 19 May at 3:15 p.m. Place: Physics Auditorium Abstract A long-term vision for a fossil free Danish energy system is frequently discussed on the political scene. This presentation deals with long term scenarios for a Danish energy system, based on renewable energy sources. In the North European region there is a very large potential for offshore wind power. Furthermore on the long timeframe, power production from photovoltage and even wavepower might be available on a big scale. A very high penetration of this kind of fluctuating power sources will be a major challenge for the power system. Some of the future elements in dealing with this challenge will be presented. The power system has to be highly integrated with the heating, gas and transportation sector to obtain the necessary flexibility to integrate these high amounts of fluctuating power sources. An integrated production of biofuels, power, heat and gas from biomass could as well be elements in an integrated energy system and will be discussed. Electric vehicles might be used for balancing short-term fluctuations. Other elements could be international integration of the power system in an offshore power grid and a gas system handling renewable gasses like biogas, hydrogen produced from wind power and other potential gasses of renewable origin. Coffee/tea and cake will be served at 3 p.m. ----------------------------------------------------------------- Prof. Ivan Stensgaard, Head of Department, Department of Physics and Astronomy, University of Aarhus, 8000 Aarhus C, Denmark, Telph: +45 8942 3715, Mobile: +45 2338 2322

[vip-all] Ferieskema 2009-2010!
by Lone Taulborg 14 May '09

14 May '09

Kære alle, Deadline for aflevering af ferieskema 2009/2010 er nu for længst overskredet, og jeg kan se på min liste, at der stadig er mange, som ikke har afleveret det nye ferieskema. Hvis der skulle være nogle, som IKKE ønsker at blive tastet for standardferie, bedes ferieskemaet afleveret til undertegnede SENEST onsdag d. 22. maj 2009! Med venlig hilsen Lone Taulborg

[vip-all] reminder: Statistical Physics seminar today
by Kate Andersen 14 May '09

14 May '09

Title: Escaping Cooperatively With Low Energies Speaker: Prof. Lutz Schimansky-Geier, Institut für Physik, Humboldt-Universität zu Berlin Time: Thursday, 14th May at 11:15 Coffee/tea and cake will be served at 11:05 Place: Room 1525-323 Abstract: We present the noise free escape of a chain of interacting units from a metastable state over a cubic potential barrier. The underlying dynamics is conservative and purely deterministic. Nonlinearity and harmonic interaction conspire such that the initially uniform lattice state becomes unstable leading to energy redistribution with strong localization. As a result a spontaneously emerging localized mode grows into the critical nucleus. By surpassing this transition state, the nonlinear chain manages a self-organized, deterministic barrier crossing. Most strikingly the noise-free, collective nonlinear escape events proceed by far faster than the transitions assisted by thermal noise. Particularly when the ratio between the average energy supplied per unit in the chain and the potential barrier energy assumes small values this enhancement of the rate of escape is of great avail.

[vip-all] AMO seminar today
by Nicolai Nygaard 14 May '09

14 May '09

Speaker: Christian P. J. Martiny (IFA) Title: Theoretical studies of strong-field ionization of atoms and molecules by few-cycle elliptically polarized laser pulses. Time: Today, 15.15 Place: Fysisk Auditorium Abstract: During the last few years, strong-field physics with laser pulses containing only a few optical cycles has emerged as an important field within atomic, molecular and optical physics. This development is paved by the experimental and theoretical progress within the field, which has resulted in a number of different applications, e.g., molecular imaging and sub-femtosecond temporal resolution of atomic and molecular processes. Strong-field ionization stands out as a process of special relevance, since it is the initial step in a number of other strong-field processes. Thus, it is important to obtain a detailed understanding of the ionization process. In this talk, I will show some theoretical results regarding strong- field ionization of atoms and molecules by few-cycle elliptically polarized laser pulses. In particular, I will describe a theoretical investigation of the recent experiment [P. Eckle et.al. Science 322, 1525 (2008)]. Peter Staanum and Nicolai Nygaard

[vip-all] Godkendelse af fakturaer i workflow: frist 15.5
by Ruth Laursen 11 May '09

11 May '09

Kære alle Vi skal senere i denne måned overgå til en ny kontoplan, og fra den 18.5 kan der ikke godkendes og klarmeldes flere fakturaer i workflow på gammel kontoplan. Derfor vil jeg bede jer om at godkende alle fakturaer STRAKS i får dem i denne uge, fordi: 15/5-2009 er sidste frist for godkendelse af købsdokumenter i eProcurement på gammel kontostreng. Husk, at hvis I har fridage m.v. skal I udpege en stedfortræder, således at vi ikke får hængepartier med fakturaer, der forbliver i cyberspace.

[vip-all] Cykler på parkeringspladsen ved køletårnene
by Ruth Laursen 11 May '09

11 May '09

Kære alle Portnerne har for en måneds tid siden fjernet alle ikke brugte cykler fra parkeringskælderen. De er placeret på parkeringspladsen mellem Fysik og Kemi ved køletårnene. De vil blive fjernet helt i løbet f en uges tid, så tjek lige efter om det skulle være en af jeres cykler.
