Abstract
We propose to investigate the effect of system dimensionality and anisotropy on the nonequilibrium dynamics on femtosecod timescale in materials with different interactions. This will be done in correlation with investigations of their functional properties. The materials to be studied include newly discovered telurides on new samples (from Stanford University), vanadates (from Groningen), bismouthates (from Oxford) and most importantly on quasi-one-dimensional nanowires of MoSI, synthesised within the group. The telurides and vanadates display complex charge and orbital ordering behaviour, which has recently been reported by Degiorgi (ETH) and Cox (Stanford) and Palstra (Groningen). The Luttinger liquid properties of the 1D MoSe system have recently been published in PRL by Kim et al. The underlying mechanisms for the observed behaviour are still to be understood, and the amount of data available on these systems is still very limited. The proposed work is tied into a number of currently running research projects of the European 6th framework programme, particularly Comephs (a STREP on Complex mesoscopic phase separation) and Eremon (Marie-Curie research program on 1D dynamics in nanosystems).
Significance for science
As expected the research has significantly advanced our fundamental knowledge of the nonequilibrium phenomena in modern functional materials such as spin and orbital ordered systems, charge ordered systems and high critical temperature superconductors. We confirmed the universality of the relaxation bottleneck formation principle as a consequence of an energy gap due to various types of long range ordering, and the importance of the fast photexcited-carrier energy relaxation to the high frequency optical phonon modes. We also showed the relaxation universality in different families of high critical temperature superconductors, which shows a presence of some kind of ordering high above the critical temperature
Significance for the country
Research is in the area of functional materials which is one of the Slovenian priorities stated in the National Research program. The project is in the area of basic research but the research is directly related to the use of new functional materials which is of direct relevance on their commercial development for real applications. Research contributed to the acquisition of new knowledge at the forefront of materials science and solid state physics research.
