SZFI SeminarRoósz GergőRMKIReal space correlations and entanglement in the 2D
Hubbard modelTuesday, 27 May 2025, 10:00, KFKI Campus, Bldg. 1, 2nd floor,
Conference RoomUsing a diagrammatic extension of the Dynamical Meanfield
Theory (DMFT), the parquet dynamical vertex approximation method, we
calculate all two-site correlation functions of the Hubbard model,
reconstruct the two-site reduced density matrix, and characterize the
correlations and entanglement using the mutual information and the fermionic
entanglement negativity. We also obtain the maximal correlation functions of
the model between two sites. As a benchmark, we compare some of the
quantities with quantum Monte-Carlo at half filling. We analyse the
correlations as a function of distance, filling, interaction strength, and
temperature. Minden érdeklődőt szívesen látunk! - Everyone is welcome to
attend.Attila Nagysem-admin AT szfki.hu
