[vip-all] AMO seminar today
by Nicolai Nygaard 03 Dec '09

03 Dec '09

N.B. We are starting a series of talks where "senior scientists" at IFA give a broad overview of their activities. Today's seminar is the first talk in this series. Speaker: Lars Bojer Madsen (IFA) Title: News from the ultrastrong and ultrafast: Theoretical femto- and attosecond science in Aarhus Time: Today, 15.15 Place: Fysisk Auditorium Abstract: The description of quantum systems driven far from equilibrium presents one of the truly open challenges to theoretical low-energy physics. The situation becomes even more challenging when the driving source, in our case an intense light field, changes on a time scale that is similar to the natural time-scale of the dynamics in the systems under investigation. The reaction of quantum systems to strong external fields continuously presents new puzzles. Numerous examples show that techniques like the time-dependent density functional theory (TDDFT), or the time-dependent multi-configurational Hartree-Fock theory (TDMCHF) face severe problems. Solving the time-dependent Schrödinger equation numerically even for a 2-electron system is presently not possible for strong femtosecond laser pulses. Not even the problem of two-photon double ionization of the helium is solved. In the talk, I will show that it is nevertheless possible to formulate theory with predictive power, and I will show examples of research performed in the “New Light Source” group. I will discuss some of the basic theoretical concepts we use to describe the strong-field driving of atoms, molecules, and surfaces, and I will present a few selected examples: (i) ionization of (oriented) molecules by tunnelling theory and time-dependent Schrödinger equation, (ii) theory for time-resolved attosecond photoelectrons spectroscopy, and (iii) Monte Carlo wavepacket theory for dissociative ionization.

Det er selvfølgelig REKTORS tale, jeg mener (og ikke dekanens).

[vip-all] Tidsændring i julearrangementet: se her
by Ruth Laursen 01 Dec '09

Kære kolleger, Det viser sig at dekanens juletale i år falder sammen med det arrangement, vi havde planlagt, derfor har vi rykket det til kl. 11.00. Så kan de der har lyst, nå begge dele. Vh Ruth TIL IFA OG ISA´s PERSONALE Traditionen tro inviterer instituttet alle medarbejdere til et arrangement, som starter med et møde med foredragsholder Connie Svendsen, <http://www.connie-svendsen.dk/> http://www.connie-svendsen.dk/ som taler om: Det lille ekstra EN PEPTALK OM ARBEJDSGLÆDE Fredag 18. december kl. 11.00 i Fys. Aud. Efter mødet, som varer 60-75 minutter, går vi i kantinen, hvor frokosten er parat. Vi håber at I alle vil slutte op om arrangementet, som vi tror, bliver både underholdende og morsomt. Det er planlagt således at man melder sig til at deltage i både foredrag og frokost. Tilmelding på listen i Informationen er senest: Tirsdag den 15. december 2009. Husk, at der kun er 96 pladser, så vent ikke til sidst! Mange julehilsner Ruth og Brian ************************************* MCj04362770000[1] ******************************************** Ruth Laursen Head of Administration Department of Physics and Astronomy Aarhus University Ny Munkegade 120 DK- 8000 Aarhus C Telephone: 8942 3706 Mobile: 2338 2335 Office: 1522-212 e-mail: <mailto:ruth@phys.au.dk> ruth(a)phys.au.dk
