The department of Physics and Astronomy was formed in January 2010 by merging the former department of Physics and Astronomy with the department of Physics and Materials Science.
The department of Physics and Astronomy has assignments within three main areas; education, research and cooperation with society, carried out within Applied nuclear physics, Astronomy and space physics , High Energy Physics, Ion Physics, Materials Physics, Materials Theory, Molecular and Condensed Matter Physics,
Nuclear Physics, Physics Education Research and Theoretical physics.
You find us at the Ångström laboratory in Uppsala.
Studying red giant stars tells astronomers about the future of the Sun and about how previous generations of stars spread the elements needed for life across the Universe. One of the most famous red giants in the sky is called Mira and lies about 400 light-years from Earth. Sofia Ramstedt is leading an international project to study binary red giant stars with ALMA and Mira is part of that study. The new high-resolution images reveal the close interaction between Mira and its companion. Despite their rather large separation, the two stars have had a strong effect on one another and the new images demonstrate how double stars can influence their environments and leave clues for what will be their future fate.
The image has been selected as ESO’s picture of the week:
Date: 20 December
Time: 18:00 h
Place: Matverkstan (http://www.mat-verkstan.se/matverkstan-pa-ultuna/)
The Christmas Party this year will, as ususal, be a traditional one with glögg, christmas food, drinks and live music.
The participation is free for staff/students. You may bring a guest for a fee of 200 SEK, to be paid to Marja Fahlander for IFA divisions and Britt Högberg for TSL.
Search for charged Higgs boson in ATLAS and development of novel technology for future particle detector systems
Representation schemes parametrize representations of associative algebras on a given vector space. I will review a derived version of this theory, due to Berest, Khachatryan and Ramadoss, and present simple examples, such as the algebra of polynomials in two variables, featuring phenomena that are visible in computer experiments, and only partly understood mathematically. I will explain the relation with instanton partition functions of N=2 supersymmetric gauge theory on R^4xS^1 and with constant term identities. (Based on joint work with Y. Berest, A. Patotski, A. Ramadoss and T. Willwacher)
The conjectured relation between higher spin theories on anti de-Sitter (AdS) spaces and weakly coupled conformal field theories is reviewed. I shall then outline the evidence in favour of a concrete duality of this kind, relating a specific higher spin theory on AdS3 to a family of 2d minimal model CFTs. Finally, I shall explain how this relation fits into the framework of the familiar stringy AdS/CFT correspondence.
