16. Collective behavior of disordered magnetic systems
Abstract : Magnetic properties of disordered and frustrated magnets have been experimentally investigated. The magnetic systems in focus in this work are spin-glasses and frozen ferrofluids (suspensions of nano-sized magnetic particles). READ MORE

17. Correlations in Frustrated Magnets : Classical and Quantum Aspects
Abstract : In this thesis, we study three different aspects of the physics of frustrated magnets. First, we study the interplay of thermal and quantum fluctuations in the transverse field frustrated Ising model on the triangular lattice. READ MORE

18. Dynamics of complex magnetic systems
Abstract : Dynamic magnetic properties of disordered and frustrated magnetic systems have beenexperimentally investigated utilising SQUID (Superconducting Quantum Interference Device)magnetometry. The studied systems are spin glasses, reentrant ferromagnets, reentrantantiferromagnets and diluted Ising antiferromagnets. READ MORE

19. Integrative modeling of intratumoral heterogeneity, plasticity and regulation in nervous system cancers
Abstract : The adult brain tumor glioblastoma (GBM) is characterized by short survival and a lack of efficient treatments. Median survival is 15 months from time of diagnosis and the 5-year survival rate is only 7 %. READ MORE

20. Stochastic Resonance and Noise-Assisted Signal Transfer : On Coupling Effects of Stochastic Resonators and Spectral Optimization of Fluctuations in Random Network Switches
Abstract : Recent research shows that noise or random fluctuations must not always be destructive in Nature by degrading system performance. On the contrary, in nonlinear systems they can synchronize systems or enhance the quality of signal transmission. The latter possibility is reported in the thesis. READ MORE
