A set of nearly good real numbers to specify the ground states associated with a Hamiltonian containing non-commutable terms and the effect of the odd-channel of a pair of different bosons emerging in multi-species systems
Yanzhang He, Yimin Liu, Chengguang Bao
A distinguishing feature of multi-species boson systems is the appearance of the odd channel, in which the spins of two different bosons are coupled to an odd integer. Through exac…
The band structure of the whole spectrum of an N-body cold system containing atoms with arbitrary integer spin and dominated by singlet pairing force
Y. Z. He, Y. M. Liu, Z. B. Li +1
The spectra of -boson systems with arbitrary nonzero spin have been studied. Firstly, only the singlet pairing interaction is considered, a set of eigenstates tog…
Sensitivity of spin structures of small spin-1 condensates against a magnetic field studied beyond the mean field theory
Chengguang Bao
The spin structures of small spin-1 condensates () under a magnetic field has been studied beyond the mean field theory (MFT). Instead of the spinors, the many body…
Spin-structures of N-boson systems with nonzero spins - an analytically solvable model with pairing force
Chengguang Bao
A model is proposed to study the possible pairing structures of N-boson systems with nonzero spin. Analytical solutions have been obtained. The emphasis is placed on the spin-struc…
Fractional Aharonov-Bohm oscillation of a two-layer ring with two electrons
Yanzhang He, Chengguang Bao
When a circular ring suffers a special topological transformation, it becomes a two-layer ring. Due to the special topology of the two-layer ring, orbital angular momenta are allow…
