The focus of the research program was in the interdisciplinary research of new materials that exhibit macroscopic manifestation of quantum phenomena, like superconductivity at high temperatures, occurrence of ferromagnetism in organics, etc. The understanding of interactions between individual excitations leading to these collective phenomena represents one of the most challenging problems in modern condensed matter physics. Among the materials that were investigated are high-temperature superconducting cuprates and similar quasi one and two dimensional inorganic compounds exhibiting charge density wave ground state, organic ferromagnets, where magnetism originates from p-orbitals, spin-Peirls systems based on fullerenes, quasi one dimensional organic systems, fullerene nanotubes and two dimensional calcogenide superconductors. Among the achievements of the research group several can be singled out: a) Studies of nonequilibrium carrier dynamics in strongly correlated electron systems. By systematic studying of femtosecond dynamics of photoexcited quasiparticles in cuprates and further theoretical modeling we were able to determine the processes governing the recovery dynamics of photoexcited superconductors back to equilibrium. Since the recovery dynamics was found to be governed by the magnitude, anisotropy and temperature dependence of the energy gap at the Fermi energy, the technique was found to be suitable for studying many different materials, including low dimensional charge density wave compounds. Our research has been reported in several publications, 5 of them were published in Physical Review Letters. b) Revealing the nature of magnetism in fullerenes. In 1991 organic compound TDAE-C60 has been synthesized, showing rather unusual physical properties. Among others, TDAE-C60 was found to be ferromagnetic below 16 K, the highest transition temperature in the ferromagnetic state reported in organics. Since the impact of having organic ferromagnets at higher temperatures would be tremendous to the industry, many groups around the world focused their research in synthesis and research of new organic ferromagnets. The main success of our group was in synthesis of several new organic ferromagnetic compounds (thus far still no other group has that succeeded in that), among which we still have a compound with a record critical temperature. Based on the success in synthesis of new materials and having single crystals of TDAE-C60 we were able to reveal the nature of ferromagnetism in fullerenes, which derives from close relation between the orientational order of molecules (structure) and magnetic interaction between molecular spins. These results are fundamental and are important not only for the understanding of molecular ferromagnetism, but also from the point of view of quantum computing. The research has been published in series of papers, among them 5 papers in Physical Review Letters and Nature. The work has also been in focus of Physics World magazine. c) Discovery of new chalcogenide based nanotubes. Carbon nanotubes are, due to their extremely interesting functional properties and high potential for applications, gaining more and more scientific attention recently. However, one of the main problems - how to obtain large amounts of ultra pure material - remains unsolved thus far. This is one of the most important reasons for the discovery of molybdenum sulphide nanotubes being so important. Namely, the method used to synthesize molybdenum sulphide nanotubes was found to have both. The first reports on synthesis and physical properties of Molybdenum Sulphide nanotubes were reported in Science, Physical Review Letters and Advanced Materials.
