Quantum Critical Behavior of Two Coupled Bose-Einstein Condensates
Feng Pan, J. P. Draayer
The quantum critical behavior of the Bose-Hubbard model for a description of two coupled Bose-Einstein condensates is studied within the framework of an algebraic theory. Energy le…
Extremal Entanglement For Triqubit Pure States
Feng Pan, Dan Liu, Guoying Lu +1
A complete analysis of entangled triqubit pure states is carried out based on a new simple entanglement measure. An analysis of all possible extremally entangled pure triqubit stat…
Staggering behavior of 0^+ state energies in the Sp(4) pairing model
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
We explore, within the framework of an algebraic sp(4) shell model, discrete approximations to various derivatives of the energies of the lowest isovector-paired 0^+ states of atom…
Energy Systematics of Low-lying Collective States within the Framework of the Interacting Vector Boson Model
H. G. Ganev, V. P. Garistov, A. I. Georgieva +1
In a new application of the algebraic Interacting Vector Boson Model (IVBM), we exploit the reduction of its Sp(12,R) dynamical symmetry group to Sp(4,R) x SO(3), which defines bas…
A simple entanglement measure for multipartite pure states
Feng Pan, Dan Liu, Guoying Lu +1
A simple entanglement measure for multipartite pure states is formulated based on the partial entropy of a series of reduced density matrices. Use of the proposed new measure to di…
Extended Pairing Model for Heavy Nuclei
V. G. Gueorguiev, Feng Pan, J. P. Draayer
We study binding energies in three isotopic chains (Sn, Yb, and Pb) using the extended pairing model with Nilsson single-particle energies. The…
