Quantum information and many body theory
The complexity of quantum many-body systems in general grows exponentially with the number of their parts. This complexity is on the one hand responsible for many interesting physical phenomena, but on the other hand also makes the study of such systems quite challenging. Quantum information theory is a relatively novel approach to analyze these systems and, in particular, to understand the correlations present in them. It also establishes connections to statistical mechanics and thermodynamics, as well as to applications.
Among the topics studied within this research direction are:
- quantum networks
- quantum thermodynamics
- quantum relative entropy
- quantum gases and field theory
