Verschränkungsstrukturen in multidimensionalen diskreten Quantum Walk Modellen
… Mittelwerte kann direkt mit den Elementen der Dichtematrix bzw. der reduzierten Dichtematrix in Zusammenhang gebracht werden. Durch kombinierte Betrachtung unterschiedlicher Erwartungswerte lassen sich auch komplizierte Verschränkungsstrukturen verstehen.

Applications of the density matrix renormalization group to mesoscopic phenomena
In this thesis, I analyze properties of mesoscopic systems that exhibit strong quantum correlations. To this purpose, I adapt and use the density-matrix renormalization group (DMRG), a numerical method that has been developed specifically for analyzing such systems. The following systems are …

The adaptive time-dependent density matrix renormalization group method : development and applications
In this work we develop a new numerical method, the adaptive time-dependent density-matrix renormalization-group (adaptive t-DMRG), which turns out to be very well suited to investigate time-dependent phenomena in one-dimensional strongly correlated systems. The method is based on the original …
