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…
A 2-level system of cold sodium atoms with high and tunable susceptibility against the magnetic field
Zhibing Li, Daoxin Yao, Yanzhang He +1
A 2-level spin-system of cold sodium atoms is proposed. Both the cases that the system has arrived at thermo-equilibrium and is in the early stage of evolution have been studied. T…
Universality in tightly bound 3-boson systems
Yanzhang He, Yizhong Fang, Chengguang Bao
The effects of two distinct operations of the elements of the symmetry groups of a Hamiltonian on a quantum state might be equivalent in some specific zones of coordinate space. Ma…
Elementary modes of excitation caused by the quadratic Zeeman term and the sensitivity of spin structures of small spin-2 condensates against the magnetic field
Yanzhang He, Chengguang Bao
The response of spin-2 small condensates to an external magnetic field is studied. The parameters of the interaction are considered as variable. The emphasis is placed on clari…
The spin evolution of spin-3 Cr Bose-Einstein condensate
Yanzhang He
The spin evolution of a Bose-Einstein condensate starting from a mixture of two or three groups of Cr (spin-3) atoms in an optical trap has been studied theoretically. The i…
