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…
