In my research, I have focussed on the experimentally relevant transport and magnetic properties of correlated electron systems, including diluted magnetic semiconductors, heavy fermion compounds and low-dimensional systems. These materials share in common unexpected properties which can not been explained with conventional approaches.
Computer simulations are an increasingly efficient means to study correlated systems. In my research I have used a variety of computational tools, such as the dynamical mean-field theory and the dynamical cluster approximation in the study of diluted magnetic semiconductors and the density matrix renormalization group method in the area of low-dimensional materials.
In the near future, I plan to extend these investigations to nanoscale quantum dots and heterostructures of magnetic semiconductors, where the confined geometry plays a crucial role, to incorporate orbital degrees of freedom in the modeling of heavy-fermions and cuprates, to calculate transport properties in nano systems and to simulate complex materials quantitatively using parameters extracted from first principles calculations.
