6 AWARDS

Eirik Eik Svanes – Student of the year

Former student at the Department of Physics, Eirik Eik Svanes, was awarded by Ragnar and Winnie Mathisens University College Fund for best graduated engineer student at NTNU.

Turid Worren Reenaas best team builder in 2011

At the 2011 graduation ceremony, the Faculty of Natural Sciences and Technology honors and award one staff member who has drawn attention as a team builder. In 2011 Turid Worren Reenaas was – most deservingly – awarded for her efforts to promote good team spirit.

Prize for younger scientist to PhD Simen Andreas Ådnøy Ellingsen

I. K. Lykkes Pris for Yngre Forskere 2011 (I.K. Lykkes Prize for Younger Scientists 2011) was given to former student at the Department of Physics, Simen Andreas Ådnøy Ellingsen. The ceremony took place at The Royal Norwegian Society for Sciences and Letters, March 11, 2011.

Research Prize to Associate Professor Ragnvald Mathiesen

Associate Professor, Ragnvald Mathiesen, was in January 2011 awarded with a Nordic research price for his research on congelation metals. The award is given by the Jernkontoret, the Swedish Steel Producers Association.

7 HIGHLIGHTS FROM THE ACTIVITY

Arne Brataas appointed as Fellow at the American Physical Society

Professor Arne Brataas at the Department of Physics has been appointed as Fellow at the American Physical Society (APS). The appointment is based on his research on electron spin: "Spin transport and dynamics in magnetic nanostructures and mesoscopic systems".

Alex Hansen head of IUAP

The International Union of Pure and Applied Physics intends to assist in the worldwide development of physics. In 2011 Professor Alex Hansen was appointed head of the Commission on Computational Physics (C20) and elected as the IUPAP Council Vice President.

This method is based upon the path integral formulation of quantum mechanics. Equivalence to standard quantum mechanical theory is verified. Earlier the method has been used to recover induced Casimir interactions due to the quantized electromagnetic field. The van der Waals interaction is a special case of the latter where retardation effects are neglected. Now ab initio Hatree-Fock and density functional theory evaluations of molecular energies can be regarded as a statistical mechanical problem to which van der Waals interactions can be added as a leading perturbation that give contributions to molecular energies from non-local correlations.

When this lattice is commensurate with the underlying crystal lattice the result is an isolator. But if it does not fit into the underlying lattice the separate electron lattice may be free to slide to make a superconductor.

Surface structure and reactivity (Ø. Borck , K. Nigussa, K. L. Nielsen, J. A. Støvneng) Solid Cr2O3 has a range of applications within catalysis and corrosion resistance. Insight into its geometric and electronic surface structure as well as its reactions with relevant atoms such as H, Cl, and S, is obtained with calculations based on gradient corrected density functional theory. Adsorption energies vary significantly with type of Figure 3. Scaling behavior for deviations from critical surface termination.

Heat transport in disordered lattices (K. Olaussen, A. Kværnø, A. Mushtaq) We have used the Langevin equation to analyse heat transport through a one-dimensional lattice with disordered parameters. In the case of linear dynamics this system can be solved by diagonalization, but one finds that the system will essentially never reach a completely stationary state, due to existence of modes with very long relaxation times (much longer than the lifetime of the universe measured in Planck units).
