[vip-all] Ultracold Atoms Talk - Sascha Zöllner Tomorrow
by Nikolaj Thomas Zinner 18 May '11

18 May '11

Speaker: Sascha Zöllner, NBI Torsdag 19. maj 2011 15.15 in 1525-323 Title: Impurities in a Two-Dimensional Fermi Gas Abstract: The state of an impurity atom immersed in a quantum gas is a fundamental model of many-body physics. In this talk, I discuss how such a simple model can tell us something about highly imbalanced Fermi gases ? i.e., a Fermi gas of one component with a low concentration of a ?minority? species added. The picture that emerges is that: For weak attraction between impurity and majority atoms, the state is well described by an impurity atom dressed by particle-hole excitations of the Fermi gas (often called a ?polaron?). For stronger attraction, a sharp transition occurs to a simple ?dimer? state of the impurity with one majority atom ? at least in three dimensions. I argue that in lower dimensions, the situation is more subtle, and particle-hole fluctuations play a crucial role. This also has implications for small ensembles of impurities, where quantum statistics come into play. ---------------------------- Nikolaj Thomas Zinner, Ph.D. Department of Physics and Astronomy University of Aarhus Ny Munkegade 120 DK-8000 Aarhus C (+45)8942 3653 phone (+45)8612 0740 fax Office: 1520-534 E-mail: zinner(a)phys.au.dk URL: http://www.phys.au.dk/~zinner

[vip-all] Nyt fra Økonomicenter Science
by Ruth Laursen 18 May '11

18 May '11

Kære alle, Til orientering. Det med beløbsgrænsen for indtastning af rekvisitioner vil jeg drøfte med Sanne, for det gælder ikke alle leverandører at faktureringen flyder løbende. F.eks. er leverancer gennem NFIT ofte flere måneder undervejs I systemet, fordi det er interne posteringer. Vh ruth ***************************** Ruth Laursen Head of Administration Department of Physics and Astronomy Aarhus University Ny Munkegade 120 DK - Aarhus C e-mail: ruth(a)phys.au.dk Phone: +45 8942 3706 Mobile: +45 2338 2335 Office: 1522-212 Kære alle, Som de fleste nok er jer bekendt så vender Lone Taulborg snart tilbage fra sin barsel. Helt præcist tirsdag d. 24/5. I den anledning har vi benyttet lejligheden til at få strømlinet de sidste af arbejdsgangene i ØCS. Som bekendt har den faglige organisationsproces resulteret også i organisatoriske ændringer på de administrative søjler. Det er således besluttet, at regnskabsmedarbejderne på hele AU på sigt skal placeres i et samlet transaktionscenter. Lones stilling har hidtil været delt mellem regnskabsarbejde og projektadministration og vil fremadrettet udelukkende bestå af projektadministration. Regnskabsarbejdet, dvs. fakturaer og rejser for hele IFA (herunder ISA) vil fremover blive varetaget af Elisabeth. Mie, som har været barselsvikar for Lone, vil i overgangsperioden beholde disse opgaver og på kyndig vis få lært Elisabeth op så ingen opgaver falder til jorden og effektiviteten opretholdes. I samme åndedrag er det besluttet, at kun rekvisitioner med en købsfaktura ex. moms på 20.000 kr. eller derover vil blive tastet på ordren. Erfaringen viser, at fakturaerne flyder så fornuftigt, at den månedlige status man får på sine projekter vil være fint retvisende på baggrund af regnskabstal. De ordrer der naturligvis er relevante som ordrer er de større anlæg hvor processen ofte er længere, derfor denne grænse. Fra 1. juli vil vi desuden overgå til, at vi udsender NAT rapporter en gang om måneden. Disse giver det fulde overblik over et givent projekt. En resultatopgørelse; forbrug+budget i en oversigt, ansættelser + de enkelte posteringer. Vi ved fra erfaring at forskerne på de andre institutter er glade for disse oversigter. Oversigterne udsendes ca. medio i måneden og medtager regnskabstal til og med måneden forinden. Dvs. NAT rapporterne for juli vil indeholde tal til og med juni måned. Vi håber, at I vil modtage Lone (og Elisabeth) med venlighed og tålmodighed så de på bedste vis kan sætte sig ind i deres nye arbejdsfunktioner og finde sig til rette med disse. Har I spørgsmål er I naturligvis altid velkomne til at rette henvendelse til os.

[vip-all] SUBATOMIC PHYSICS FOREDRAG i dag kl. 15.15 / SUBATOMIC PHYSICS talk today at 3.15 p.m.

>From nuclear reactions to astrophysics Studies of stellar processes using charged-particle and gamma-ray spectroscopy Speaker: Christian Aa. Diget, Department of Physics, University of York, UK Time: Wednesday, May 18 at 15.15-16.00 Location: Building 1520-516 Nuclear processes driving the energy production and nuclear synthesis in stars often cannot be studied directly in the laboratory. This is because the reactions in many cases involve short-lived nuclei, and are furthermore hindered by the Coulomb repulsion of the nuclei, making direct observation of the reactions difficult or even impossible. In this category are the reactions related to the breakout from the Hot-CNO cycle in for example X-ray bursts, a nuclear run-away on the surface of neutron stars. Instead of direct measurements the reactions must be studied indirectly, typically in reaction studies which probe the nuclear structure that determine the astrophysical processes. The Silicon Highly-segmented Array for Reactions and Coulex (SHARC) [1] is a new multipurpose array for charged-particle detection designed to address a diverse set of outstanding nuclear-physics questions, including indirect studies of astrophysical reactions and studies of nuclear structure. The array is used for radioactive-ion-beam studies at the ISAC-II accelerator at TRIUMF, Canada [2] in conjunction with the TIGRESS -ray spectrometer [3]. The first experiments utilising the array have now been completed using a range of different reactions such as transfer of neutrons, a deuteron, or an alpha particle as well as utilizing deep inelastic scattering of radioactive nuclei on a heavy target. Specific examples are the newly performed indirect study of the Hot-CNO breakout reactions 18Ne + alpha ! 21Na +proton reaction and the planned 15O + alpha ! 19Ne + gamma reaction study. [1] C. Aa.

[vip-all] AMO seminar today, 15:15
by Aurélien Dantan 12 May '11

12 May '11

Title: Radioastronomy and the search for complex and prebiotic molecules in the Interstellar Medium Speaker: Cécile Favre, IFA Time: Thursday, May 12, 15.15 to 16.00 Place: Fysisk Auditorium Abstract: Over 150 different molecular species have been detected in the interstellar and circumstellar media, almost all by radioastronomy. Among these, 60 are complex molecules. The interstellar processes that form more or less complex molecules, either within the ices on grains surfaces or in the gas phase, are not those commonly encountered on Earth. The only way to constrain chemical models of molecules formation is through the observation and the analysis of the emission coming from molecular species. I will discuss molecular mm-wave observations that allow the deduction of physical properties of a region (temperature, abundance and dynamics) and how spectral confusion makes difficult the identification of low abundance molecules. Using high angular and spectral resolutions reached with radio interferometers as the Plateau de Bure Interferometer (PdBI) and the Expanded Very Large Array (EVLA), I will discuss some very new results on methyl formate toward Orion-KL, a highly active massive star forming region. Jacob Sherson and Aurélien Dantan Coffee, tea and cake will be served at 15.05 ----------------------------------- Aurelien Dantan Ion Trap Group Department of Physics and Astronomy University of Aarhus Ny Munkegade, bygn. 1520 8000 Aarhus Denmark +4589423602

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

11 May '11

GENERAL PHYSICS COLLOQUIUM _____ Title: Slow antiprotons and the secrets of atomic collisions Speaker: Helge Knudsen, Department of Physics and Astronomy, Aarhus University Time: Wednesday, 11 May, 2011 at 3:15 p.m. Place: Physics Auditorium, 3rd floor, Department of Physics Abstract One of the first successes of quantum theory was the accurate description of the structure of the isolated hydrogen atom. Due to difficulties with the inclusion of the interaction between its two electrons, it took years to reach a similar accuracy for the helium atom. heliumioniantiprotToday, 90 years later, similar progress has not yet been achieved in the case of atomic collisions, where a description of dynamic systems involving several electrons is needed. Even for the "theorists dream system", namely the collision of a slow antiproton on a helium atom leading to the liberation of one electron, for which a large number of advanced theoretical calculations exist, these differ by up to 30%. Since 1986, our group has been investigating such processes at CERN, starting with very fast projectiles, but recently we developed a new scheme for the creation of a DC beam of slow (a few keV) antiprotons at CERN, and we have now obtained benchmark data stretching over many decades of projectile energy for the development of more accurate theoretical calculations. The use of antiprotons instead of other ions is important, since antiprotons, due to their negative charge, do not support the process where electrons are transferred to the slow projectile. This simplifies the already difficult task of the theorists. _____ Coffee/tea and cake will be served at 3 p.m. David Field
