SUMMARY:TRR 360 Seminar: Discerning and mitigating complex quantum correlations in many-body dynamics Jan Budich
DESCRIPTION:Discerning and mitigating complex quantum correlations in many-body dynamics \nJan BudichTU Dresden \nThe proliferation of complex quantum correlations in many-body dynamics poses a formidable challenge both to quantum information science at a fundamental level and to classical variational approaches such as tensor network methods at a practical computational level. In this talk\, after a brief introduction to the broader field\, we discuss two of our recent contributions towards discerning various sources of quantum correlations and mitigating dynamical growth of entanglement. First\, noting that entanglement depends on how a system is partitioned into subsystems (entanglement cut)\, we explore the potential of dynamically adjusting the entanglement cut as a strategy for reducing entanglement growth. Second\, regarding the dynamics of mixed states such as locally perturbed thermal states\, we demonstrate how tools from differential geometry such as parallel transport can be harnessed to tame the temporal growth of quantum correlations in a purified state corresponding to the physical mixed state. \n\n\n\n\n\n\nVenue
