Exploring quantum impurities and measurement backaction via tensor-networks

Oded Zilberberg

Universität Konstanz

Tensor networks allow us to compress and efficiently represent one-dimensional many-body states. This relies on truncating small correlations and entanglement along the system’s length. At the same time, the representation provides easy access to these correlations. My talk will be divided into three parts: (i) I will introduce a mesoscopic coupled quantum-dots system, map it onto a Wilson chain, and show how to study Kondo physics via the tensor network correlations as order parameters, (ii) I will introduce how the tensor network description of a mixed state provides an easy-to-read entanglement measure for open systems, and (iii) show how the entanglement measure allows us to better understand measurement-induced transitions (MITs).
