“…The fine tunability and the wonderful controllability in BEC experiments provide an excellent testbed for many theoretical predictions [11][12][13][14][15][16][17][18]. In fact, the DIs exist not only in scalar (single-component) BECs, such as solitons [19] and vortices [20], but also in spinor BECs, including the two-component and threecomponent spinor BECs, where vector solitons [21], Skyrmion vortices [22,23], and spin domains/textures are explored [24][25][26][27][28][29][30].…”

Magnetic-field-induced dynamical instabilities in an antiferromagnetic spin-1 Bose-Einstein condensate

We theoretically investigate four types of dynamical instability, in particular the periodic and oscillatory type IO, in an anti-ferromagnetic spin-1 Bose-Einstein condensate in a nonzero magnetic field, by employing the coupled-mode theory and numerical method. This is in sharp contrast to the dynamical stability of the same system in zero field. Remarkably, a pattern transition from a periodic dynamical instability IO to a uniform one IIIO occurs at a critical magnetic field. All the four types of dynamical instability and the pattern transition are ready to be detected in 23 Na condensates within the availability of the current experimental techniques.

“…III. SPINOR MIXTURE OF 87 Rb AND 23 Na We next extend the above discussion for two atoms to a mixture of bosonic spinor 23 Na(η = a) and 87 Rb (η = b) atoms in the ground F = 1 states [40]. This represents a special case as their level spacing mismatch is smaller because the nuclear and electronic spins for both atoms are the same.…”

We propose a general scheme for inducing resonant exchange between spins or pseudo-spins of unmatched levels via periodic driving. The basic idea is illustrated for a system of two heteronuclear atoms, for which analytical results are provided for the effective spin exchange (SE) interaction strength. It is then applied to the mixture of 23 Na and 87 Rb atoms with a radio-frequency (rf) or microwave field near-resonant to the mismatched Zeeman level spacings. SE interaction engineered this way is applicable to ultracold quantum gas mixtures involving spinor Bose-Bose, Bose-Fermi, and Fermi-Fermi atoms.This paper presents a general scheme for promoting arXiv:1805.02310v1 [cond-mat.quant-gas]

Spontaneous separation of large-spin Fermi gas in the harmonic trap: a density functional study

The component separation of the trapped large-spin Fermi gas is studied within density functional theory. The ground state and ferromagnetic transition in the gas, with and without the spin mixing collision, are calculated. In the absence of spin mixing, two patterns of separation are observed as the interaction between atoms increases, whereas only one of them corresponds to a ferromagnetic transition. The phase diagram suggests that the pattern which the system chooses depends on the interaction strength in the collision channels. With the presence of spin mixing, the distribution of phase region changes because of the interplay between different collision channels. Specifically, the spin exchange benefits the FM transition, while it suppresses the component separation of CS-II pattern.
