Description
It is nowadays well established that many-body quantum systems
in one and two spatial dimensions exhibit unconventional collective behavior that gives rise to intriguing novel states of matter.
Examples are topological states exhibiting nonabelian statistics
in 2D and spin-charge separated metals and Mott insulators in 1D.
An important focus of current research is to characterize both
equilibrium and non-equilibrium dynamics of such systems. The latter
has become experimentally accessible only during the last decade and constitutes one of the main frontiers of modern theoretical physics.
In recent years it has become clear that entanglement is a useful
concept for characterizing different states of matter as well as non-equilibrium time evolution. In this talk, I will review some
the most important results in the field and I will speculate on how
these results can be used to disentangle these complex quantum systems.
