05 Mar '09

Kære kollegaer, (English version below) Jeg minder om, at Dansk Fysisk Selskab afholder Årsmøde i dagene den 16. til 18. juni på DTU, Lyngby. Denne gang er årsmødet et fællesmøde for de Nordiske Fysiske Selskaber. Du kan finde en reklame - med liste over plenarforedrag - på opslagstavlerne eller på http://dfs.nbi.dk/aarsmoeder/2009/aarsmoede.php BEMÆRK: Dine specialestuderende kan søge friplads og hoteludgift ved DFS og da IFA betaler deres bustransport, kan de få to dage i København med stribevis af interessante fysikforedrag GRATIS (de skal bare være medlem af DFS, og det koster kun 150 kroner om året). Sidste år fik alle, der ansøgte, bevilget friplads og overnatning! NETVÆRK: Dette er en super chance for at møde dine kolleger fra de andre danske og nordiske universiteter og industrien. BIDRAG: Du opfordres til at indsende et bidrag til en af de videnskabelige mundtlige eller poster sessioner. DEADLINE: Tilmelding inden 20. marts, hvis du vil indsende et konferencebidrag (eller hvis dine studerende vil søge friplads). KONFERENCEGEBYR: 150 EURO for DFS medlemmer. BUSTRANSPORT: Med støtte fra IFA: 500 Dkr. Tilmeld dig på listen i receptionen senest 8. juni og betal ved samme lejlighed. MVH Helge Knudsen DFS kasserer ************************************************ Dear colleagues, The annual meeting in the Danish Physical Society is an excellent opportunity to get an overview of the activities in the fields of physics and astronomy in Denmark. The next meeting will be held 16. 18. June 2009 at the Danish Technical University, Copenhagen. <http://dfs.nbi.dk/aarsmoeder/2009/aarsmoede.php> http://dfs.nbi.dk/aarsmoeder/2009/aarsmoede.php This year the meeting will be held together with the Physical Societies of the other Nordic countries, even further broadening the scope. Deadline for registration and abstracts: March 20. Joint bus transport from the University of Aarhus to the conference site (and back) is provided with support from the Department (IFA) for 500 Dkr. You are kindly requested to put your name on the list for transportation which is situated in the reception and to pay the 500 Dkr at the same time - at the latest June 8. Sincerely Helge Knudsen (Board member in the Danish Physical Society) ___________________________________ Helge Knudsen Department of Physics and Astronomy Aarhus University Ny Munkegade 120 DK 8000 Aarhus C Denmark (+45) 8942 3607 ___________________________________

[vip-all] AMO-seminar at 10.15: Internal-state and motional dynamics of trapped Ca+ ions in a Penning trap
by Peter Staanum 02 Mar '09

02 Mar '09

Speaker: Danny Segal, Department of Physics, Imperial College London, UK Title: Internal-state and motional dynamics of trapped Ca+ ions Time: Tuesday, March 3, 10.15 to 11.00 Place: 1525-323 We are undertaking a programme of work aimed at demonstrating the feasibility of using ions held in Penning traps for applications in Quantum Information Processing (QIP). I will discuss two recent experiments we have conducted. (i). A number of applications of ions in Penning traps have involved shuttling ions from one trapping zone to another, separated by distances of centimetres, along the axis of the applied magnetic field. For QIP applications shuttling over small distances in a direction perpendicular to this axis is desirable but this is complicated by the presence of the v×B component of the Lorentz force. With this application in mind, we have designed, built and operated a mm-scale multiple Penning trap structure using printed circuit board. In a preliminary test of shuttling in this structure we have demonstrated the controlled movement of small clouds of ions from one trapping zone to another in ~2.5 ?s, in a direction perpendicular to the magnetic field axis. (ii). The large magnetic field of the Penning trap causes mixing of states with different values of the J quantum number. Transitions that are strictly forbidden in the absence of the magnetic field become partially allowed. Interestingly, the electron shelving technique makes the presence of rather small state admixtures remarkably easy to detect. This effect has a bearing on the fidelity of the readout process in our system. Coffee, tea and "rundstykker"(!) will be served at 10.05 Nicolai Nygaard and Peter F.
