Towards a fully size-consistent method of increments
E. Fertitta, D. Koch, B. Paulus +2
The method of increments (MoI) allows one to successfully calculate cohesive energies of bulk materials with high accuracy, but it encounters difficulties when calculating whole di…
On the calculation of complete dissociation curves of closed-shell pseudo-onedimensional systems through the multireference method of increments
Edoardo Fertitta, Beate Paulus, Gergely Barcza +1
The Method of Increments (MoI) has been employed using a multireference approach to calculate the dissociation curve of beryllium ring-shaped clusters Be of different sizes. Be…
Phase Separation of Superfluids in the Chain of Four-Component Ultracold Atoms
G. Barcza, E. Szirmai, J. Sólyom +1
We investigate the competition of various exotic superfluid states in a chain of spin-polarized ultracold fermionic atoms with hyperfine spin and s-wave contact interacti…
Investigation of metal-insulator like transition through the ab initio density matrix renormalization group approach
E. Fertitta, B. Paulus, G. Barcza +1
We have studied the Metal-Insulator like Transition (MIT) in lithium and beryllium ring-shaped clusters through ab initio Density Matrix Renormalization Group (DMRG) method. Perfor…
Entanglement patterns and generalized correlation functions in quantum many body systems
G. Barcza, R. M. Noack, J. Sólyom +1
We introduce transition operators that in a given basis of the single-site states of a many-body system have a single non-vanishing matrix element and introduce their correlation f…
Emergence of Quintet Superfluidity in the Chain of Partially Polarized Spin-3/2 Ultracold Atom
G. Barcza, E. Szirmai, Ö. Legeza +1
The system of ultracold atoms with hyperfine spin might be unstable against the formation of quintet pairs if the interaction is attractive in the quintet channel. We have…
