Quantum criticality on compressed lattices Prof. Dr. Markus Garst Karlsruher Institut für Technologie   At a quantum phase transition, the ground state of a system changes as a function of a non-thermal control parameter. In a solid, the associated quantum critical degrees of freedom generically couple to the crystal lattice. This coupling is potentially able to change […]

Exploring quantum impurities and measurement backaction via tensor-networks

Oded Zilberberg

Technical University Munich + Zoom

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 […]
