[vip-all] General Physics Colloquium today at 3 pm
by Trine B.Mortensen 15 Jun '11

15 Jun '11

GENERAL PHYSICS COLLOQUIUM _____ Title: Attosecond science: shining new light on old questions in quantum mechanics Speaker: Ursula Keller, ETH Zürich, Physics Department, Zürich, Switzerland Time: Wednesday, 15 June, 2011 at 3:15 p.m. Place: Physics Auditorium, 3rd floor, Department of Physics Abstract Continued progress in novel light sources enables improved understanding of how matter functions, and how energy and charge are transported on an atomic scale. This research is necessary to further develop key basic physical understanding required to address important challenges such as alternative energy sources and improving health. Theoretical models often fail to describe the dynamics due to numerical limitations, and we need to develop better approximate models for the ultrafast dynamics on an atomic scale, where quantum mechanics becomes essential. Novel time-resolved attosecond streaking techniques such as energy streaking and the attoclock are currently being applied in an attempt to answer a very fundamental question in quantum mechanics: how fast can light remove a bound electron from an atom or a solid? For example two different techniques addressed two different fundamental processes: strong laser field ionization, where a the strong laser field bends the binding potential to emit an electron by tunnelling (tunnel ionization) and the photoelectric effect, where a single light quanta (a photon) is absorbed to emit an electron (photoemission). In the first case, an instantaneous tunnelling delay time in helium was measured within the experimental accuracy of around 10 as, and in the latter case, a relative delay in photoemission of about 20 as between electrons originating from different bound states in neon was measured - from a semi-classical point of view a somewhat puzzling outcome! Strong laser field ionization involves the absorption of many photons, and furthermore the electron emitted into the continuum (i.e. an unbound state) initially experiences a spatial separation from the ion of more than ten atomic units. For photoemission, in contrast, only one photon is absorbed without any initial lateral displacement. Why does photoemission, in contrast to tunnel ionization, have a measurable emission delay, we may wonder? As we know, quantum mechanics may give unexpected results as viewed from a classical perspective. Future results should hopefully help to resolve this potential controversy and give us a better physical picture to understand attosecond quantum mechanics. _____ Coffee/tea and cake will be served at 3 p.m. David Field

[vip-all] Party on 17 June - street closure and practical information
by Ruth Laursen 14 Jun '11

14 Jun '11

Dear colleagues As you are no doubt aware, AU is holding a party on Friday 17 June, and a certain amount of preparation is required. This can have an influence on your work environment on 17 June and the preceding few days. * Certain parking spaces will be used for delivery and storage, and these will therefore be blocked off from Wednesday 15 June. Bartholins Allé - from the Lakeside Lecture Theatres and northwards - form part of the contingency plan as a road for ambulances, and must therefore not be used for parking on 17 June. The closure area will be marked a few days before blocking off the parking spaces. * All roads into the University Park will be closed to traffic on Friday 17 June from 13.00. All road closures will be manned by marshals who will ensure that people on official business at the university can naturally drive in and out again. * Sound testing will be carried out in the University Park from 13.00 on the day of the party. The project management for the party has held discussions with those responsible for activities such as examinations and conferences that could be particularly inconvenienced by this. * The university's neighbours have been notified of the party and any related noise. This applies to private individuals, businesses, the State and University Library and museums. * This is a private party for staff and students at AU, and all entrances will therefore be manned by marshals who can request to see your ID card or key card. A summary of night and city bus services and alternative car parks is available at Celebration of Tomorrow's AU <http://medarbejdere.au.dk/en/tomorrowsau/celebration-of-tomorrows-aarhus-un…> . A map of the area (in Danish only) shows the road closures, bus stops and taxi stands, as well as the drop-off and pick-up points for bus transport for colleagues who work outside the Aarhus Campus. We hope you have a really great party.

Kære kolleger Fredag den 17. juni er der som bekendt fest, og det kræver nogle forberedelser. Disse forberedelser kan få indflydelse på din arbejdsdag den 17. juni og i dagene op til. * Visse parkeringspladser skal bruges til leverancer og depoter, og spærres derfor af fra onsdag den 15. juni. Bartholins Allé fra Søauditorierne og nordpå indgår i beredskabsplanen som ambulancevej og må derfor ikke benyttes til parkering 17. juni. Der sættes en markering op om afspærring et par dage før parkeringspladserne inddrages. * Alle veje ind til Universitetsparken spærres af for bilkørsel fredag 17. juni fra kl. 13. Ved alle vejspærringer er der vagter, som sørger for, at personer med et nødvendigt ærinde på universitetet naturligvis kommer ind og ud igen. * Der er lydprøver i Universitetsparken fra kl. 13 på festdagen. Fest-projektledelsen har været i dialog med de ansvarlige for f.eks. eksamener og konferencer, som i særlig grad måtte blive generet af dette. * Naboer til universitetet er orienteret om fest og støj. Det gælder både private, erhverv, Statsbiblioteket og museer. * Festen er en lukket fest for medarbejdere og studerende på AU, og derfor vil der ved alle indgange være vagter, som kan bede om at se dit medarbejderkort/nøglekort.

[vip-all] Seminar today at 14.30 - Alberto Imparato
by Trine B.Mortensen 07 Jun '11

07 Jun '11

Title: Discrete Breathers in Model Proteins Speaker: Alberto Imparato Time: 7 June 2011 at 14.30 Place: Room 1520-616 Abstract I will present the results of our last paper S.Luccioli, A.Imparato, S.Lepri, F.Piazza, A.Torcini Discrete Breathers in a Realistic Coarse-Grained Model of Proteins to appear in Phys. Biol. We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of nonlinear origin (discrete breathers) emerge naturally as continuations of a subset of high-frequency normal modes residing at specific sites dictated by the native fold. In the case of the small $\beta$-barrel structure that we consider, localization occurs on the turns connecting the strands. At high energies, discrete breathers stabilize the structure by concentrating energy on few sites, while their collapse marks the onset of large-amplitude fluctuations of the protein. Furthermore, we show how breathers develop as energy-accumulating centres following perturbations even at distant locations, thus mediating efficient and irreversible energy transfers. Remarkably, due to the presence of angular potentials, the breather induces a local static distortion of the native fold. Altogether, the combination of these two nonlinear effects may provide a ready means for remotely controlling local conformational changes in proteins. Alberto Imparato

[vip-all] Cykelkælder klar til ansatte ved IFA
by Ruth Laursen 01 Jun '11

01 Jun '11

Kære alle Nu er cykelkælderen genetableret i et mindre omfang. Det betyder at vi kun kan have parkerede cykler fra ansatte ved IFA. Alle parkerede cykler skal derfor fremover være forsynet med en label, der placeres på saddelpinden af cyklen. ID labels til dette kan fås ved henvendelse til Birthe i Informationen. Parkerede cykler uden ID vil blive stillet op på parkeringspladsen.
