SZFI SeminarMáté MihályHUN-REN Wigner RCP SZFIStudying strongly correlated 
systems with tensor network methods and partitioning techniquesTuesday, 1 
July 2025, 10:00, KFKI Campus, Bldg. 1, 2nd floor, Conference RoomIn general, 
there is no universally superior method in quantum chemistry that 
simultaneously offers both high accuracy and low computational cost. Tensor 
network methods, where the computational demands are governed by the tensor 
ranks, have become vital tools for addressing strongly correlated, that is, 
multireference problems in quantum chemistry. Hybrid tensor network 
approaches can be developed to capture the correlation in the system [1,2], 
which will be discussed in the context of partitioning techniques and 
perturbation theory [3].[1] Faulstich, Máté, Laestadius, Csirik, Veis,
