[vip-all] Talents
by Ulrik Ingerslev Uggerhøj 21 Jun '18

21 Jun '18

Dear all, As a follow-up for the residential meeting at Vejle, before which I only had response from 2 groups, I kindly ask you to - groupwise, if possible - inform me in writing about your planned activities in connection with talent students: "Please also take responsibility for organizing suggestions for host groups for “Talent students” (i.e. students being admitted to the talent program from their second year); such groups may consist of the entire topical group or one or more subgroups." Please include in your (preferably brief) response which (sub-)groups you suggest, 5-10 keywords about the scientific content, and a bit about which competencies you expect the talent students may obtain from your programme (both the 'soft' such as presentation skills, and the 'hard' such as programming in LabVIEW), and a suggestion for the final evaluation, to be done at the end of the 1/2 year (which product?).

Kære alle Sidste år genoplivede vi traditionen med børnejuletræsfest. Vi gentager den hyggelige begivenhed og afholder festen Tirsdag den 9. december 2014 kl. 16.00 i Fysisk Kantine Se den vedhæftede invitation og husk at tilmeldingsfristen er den 28. november. Vi håber at se rigtig mange kolleger, børn og børnebørn til en hyggelig eftermiddag. Med venlig hilsen PS! Personale og studerende ved IFA og ISA Dear all, Last year we reintroduced the "Children's Christmas Party " tradition. We repeat the cosy event and the party will be held Tuesday the 9th of December 2014 at 16.00 in Fysisk Kantine Please see the attached invitation (in Danish only) and remember that the deadline for sign-up is 28th of November. Sign up and pay with Birthe at the Information desk. We hope to see many colleagues, children and grandchildren to an afternoon filled with Danish "hygge". Best regards, PS!

[vip-all] Dansk Fysisk Selskabs Åbningsmøde til Lysets År 22-23 januar
by Helge Knudsen 22 Dec '14

22 Dec '14

Kære kollega, Det er nu muligt at registrere til Dansk Fysisk Selskabs Åbningsmøde til Lysets År. Man kan kun deltage i arrangementet, hvis man har registreret. Bemærk, at posterholdere kommer med for halv pris 300 DKK, da Dansk Fysisk Selskab har ønsket at opmuntre alle, inklusive studerende, til at præsentere en poster. I tilfælde af overtegning vil de, der deltager i hele arrangementet, middag torsdag aften og frokost fredag, som deltagere eller posterholdere få fortrinsret. Gå ikke glip af dette enestående arrangement - der kan registreres via DFS' hjemmeside www.dfs.nbi.dk<http://www.dfs.nbi.dk>, hvor der også er flere oplysninger om arrangementet. Vil du være venlig at gøre dine speciale- og PhD studerende opmærksomme på dette arrangement? Jeg ønsker hermed alle en glædelig jul og et godt nytår.

[vip-all] Efterlysning - search for power supply
by Ruth Laursen 19 Dec '14

19 Dec '14

If you do not put your legs in labs, please ignore this email.... For the rest of you: We are missing a power supply for our electrospray-ion source at Saphira (ion storage ring) - see the photo. It was last seen in the storage room at 1. floor some time ago. If you know where to find it, please write to Lars Andersen (lha(a)phys.au.dk) or Hjalte Kiefer (Hjalte(a)phys.au.dk) Many thanks, Lars ****************************************************

[vip-all] GPC seminar today at 15:15 - Seth Putterman
by Karin Vittrup 17 Dec '14

17 Dec '14

General Physics Colloquium Wed. 17th December 15:15-16:00 Fys. Aud. Title: Unknowns of energy concentrating phenomena Speaker: Seth Putterman, Physics Department UCLA Abstract: The path to equilibrium is not controlled by entropy production. Although entropy increases with every time step, dynamical motion can be dominated by nonlinear physical process which spontaneously concentrate energy density. In sonoluminescence a bubble concentrates the energy of a traveling sound wave by 12 orders of magnitude to create picoseconds flashes of blackbody radiation that originate in a new state of matter. When surfaces are brought into and out of contact they exchange charge: a process call tribo-electrification. This phenomenon can be so strong that the power applied to peel sticky tape is efficiently transduced into a flux of high energy electrons, and x-ray photons that can expose an image in a few seconds. For a ferroelectric crystal, instabilities in the phonon spectrum lead to a spontaneous polarization that for Lithium Niobate reaches 15.million volts per cm. The temperature dependence of this field can be used to build a neutron generator based on the fusion of deuterium nuclei. These phenomena challenge a reductionist approach to the theoretical physics of emergent phenomena. The degree to which the energy density of a continuous system can be concentrated by off-equilibrium motion has not been determined by theory. For sonoluminescence we do not know if the parameter space includes a region where an extra factor of 100 in energy density makes it possible to realize thermonuclear fusion. For triboelectrification we do not have an ab-initio theory of charge transfer. And for ferroelectrics we do not have an ab-initio theory of the limits of spontaneous polarization which can be designed. Wine and cheese will be served at 4 PM
