Tensor network state ansatz for systems of continuously confined fermions

Ors Legeza
Hungarian Academy of Sciences, Hungary


In this contribution, we overview tensor network states techniques that can be used for the treatment of high-dimensional optimization tasks used in many-body quantum physics with long range interactions and ab initio quantum chemistry. We will also discuss the controlled manipulation of the entanglement, which is in fact the key ingredient of such methods, and which provides relevant information about correlations. Recent developments on fermionic orbital optimization, externally corrected coupled cluster density matrix renormalization group (TCCSD-DMRG) will be presented. Finally, new results will be shown for systems of continuously confined fermions in light of Generalized Pauli Principle.
