Determining the ensemble N-representability of Reduced Density Matrices
Ofelia B. Oña, Gustavo E. Massaccesi, Pablo Capuzzi +5
The N-representability problem for reduced density matrices remains a fundamental challenge in electronic structure theory. Following our previous work that employs a unitary-evolu…
Modeled vortex dynamics on a Bose-Einstein condensate in a rotating lattice
P. Capuzzi, D. M. Jezek
We study the dynamics of vortices in a Bose-Einstein condensate within a rotating four-site lattice which can be effectively described by a multimode model. Such a vortex dynamics…
Determining the N-representability of a reduced density matrix via unitary evolution and stochastic sampling
Gustavo. E. Massaccesi, Ofelia. B. Oña, Pablo Capuzzi +6
The N-representability problem consists in determining whether, for a given p-body matrix, there exists at least one N-body density matrix from which the p-body matrix can be obtai…
Dynamics in multiple-well Bose-Einstein condensates
M. Nigro, P. Capuzzi, H. M. Cataldo +1
We study the dynamics of three-dimensional weakly linked Bose-Einstein condensates using a multimode model with an effective interaction parameter. The system is confined by a ring…
