New Chief Administrator at NORDITA

Nordita welcomes Daniela Fitger who started as Chief Administrator in January. She is responsible for overseeing the daily operations of Nordita, and for providing internal and external coordination, management, and oversight of all administrative activities related to the development and implementation of the mission and goals of Nordita. Daniela has a Master's degree in economics and was previously a project manager at ALMI Företagspartner. She is originally from Ecuador.

Six new NORDITA Fellows arriving in 2011

A total of 403 applications for NORDITA Fellowships were received this year, which is a new record (up from 356 applications the previous year). The applications were evaluated and ranked by the three Nordic Research Committees and by the NORDITA faculty. We would like to take this opportunity to thank committee members for their time and continuing commitment to NORDITA. The recipients of the six fellowships that were awarded are listed below (in alphabetical order) along with their current affiliation and field of research.

Dmitry Bykov - Trinity College Dublim - high-energy theory
Oliver Gressel - Queen Mary, University of London - astrophysics
Oksana Manyuhina - ENS Paris - condensed matter physics
Juha Suorsa - University of Oslo - condensed matter physics
Pierpaolo Vivo - ICTP Trieste - condensed matter physics
Dmytro Volin - Pennsylvania State University - high-energy theory

NORDITA Visiting PhD Student program for Fall 2011

The Visiting PhD Student program launched by NORDITA in 2010 is open for applications for visits during the 2011 Fall term. The program, primarily intended for PhD students in the Nordic and Baltic countries, offers selected students the opportunity to spend time at NORDITA and take advantage of the research environment and ongoing scientific activities at the institute and the AlbaNova University Center in Stockholm. This can, in particular, include collaboration on research projects with NORDITA academic staff and participation in NORDITA Scientific Programs in areas of interest to the students. Visiting PhD fellows may also be interested in taking PhD-level courses offered at Stockholm area universities.

A Visiting PhD Fellowship will be awarded for a period of one to three months, providing accommodation and a contribution towards travel and living expenses in Stockholm. Fellows must be registered PhD students in theoretical physics or a related subject at a university in the Nordic or Baltic countries at the time of the fellowship visit to NORDITA. Applications for the fellowship program can be submitted at and please note that only on-line applications will be considered.

Fellowships are awarded twice a year but starting dates for stays at NORDITA are flexible. Applications for Fall 2011 should be received by June 15, 2011. Please direct enquiries about NORDITA Visiting PhD Fellowships to the Director of NORDITA, Professor Larus Thorlacius (

Licentiate Thesis defence of NORDITA PhD students

NORDITA PhD students Fabio Del Sordo and Simon Candelaresi have successfully defended their licentiate theses, "Generation of Magnetic Fields on Galactic Scales" and "Magnetic Helicity Fluxes and their Effects in Dynamo Theory".

News about the NORDITA apartments

NORDITA has decided to reduce the number of apartments we rent at Gyllenborgsgatan. Only a small number of apartments for long-term visitors will be kept. Starting August 2011, participants in NORDITA Scientific Programs will be housed in a new apartment hotel Biz Apartment, which is located in the nice area of Gärdet. This will result in more flexibility and better service for NORDITA guests.

Current and upcoming Nordita Programs


Applications of network theory: from mechanisms to large-scale structure

from 28 March to 20 April 2011
The main idea is to convene key world-class researchers on complex networks and let them interact freely with the Nordic groups interested in the area. The program will be divided into four thematic areas: biological networks, general network theory, technological networks, and social networks. Many of the intended participants are interested in several of these points. A more intense, 3-day workshop will be arranged during the middle of the program.


Predictability + School on Data Assimilation

from 26 April to 27 May 2011
Predicting the unpredictable is a challenge that is common to various physical systems whose dynamics is governed by the equations of ?uid dynamics. The oldest example is weather prediction. Other examples include climate prediction, space weather forecast, and solar cycle forecast. The mathematics developed for these applications is extremely interesting and deserves more detailed understanding, so that these techniques can be used also in other areas where the application of this technique is less well developed.

String Phenomenology

from 30 May to 25 June 2011
The program will try to cover what string theory has to say about physics beyond the Standard Models of both particle physics and cosmology. Topics may include but are not limited to: string effective actions, string instantons, stringy supersymmetry breaking, intersecting D-branes, generalized ?ux compacti?cations, in?ation in string theory, string-inspired MSSM-like models and dark matter in those models.

Upcoming Conferences and Schools

Nordic Conference on Nuclear Physics 2011

from June 13 to 17 2011
An international conference covering theoretical and experimental nuclear and hadron physics that is held every four years, circulating among the Nordic countries. This year's event will be at the AlbaNova Center in Stockholm where NORDITA is located. NORDITA will provide travel support for a limited number of PhD students at Nordic universities to attend the conference.

Strings 2011

from June 27 to July 2 2011
The annual international conference on string theory will be in Uppsala, Sweden this year. Faculty members Paolo DiVecchia, Larus Thorlacius, and Konstantin Zarembo are on the National Organizing Committee and NORDITA is one of the conference sponsors.

Summer School in Random Geometry

from August 8 to 12 2011
The purpose of the school is to introduce PhD students and young researchers to a selection of topics in Random Geometry through lecture series by experts. Topics to be covered include percolation theory, statistical mechanics, random matrices, stochastic Loewner evolution and random graphs. The school is partially supported by the NordForsk network "Random Geometry" where NORDITA is a participating institute.

Nordita Board meeting

The next Nordita Board meeting will take place on the 27th of May 2011.
