Selective Tunneling Dynamics of Bosons with Effective Three-Particle Interactions

Zhen-Xia Niu, Ju-Kui Xue

The selective coherent destruction of tunneling (CDT) of ultracold Bose gas with three-particle interactions in a modulated double-well potential is discussed. It is shown that the effects of two- and three-particle interactions on the dynamics of the selective CDT are strongly coupled and the three-particle interactions significantly modify the selective CDT. For weak three-particle interactions, an upper bound of the boson number for realizing the selective CDT exists and the region of boson number for realizing the selective CDT is enlarged (reduced) with repulsive (attractive) three-particle interactions. For strong three-particle interactions, the boson number in the system for realizing the selective CDT not only has an upper bound, but also has a lower bound. The results are confirmed by numerical simulations.

Tunneling dynamics of a few bosons with both two- and three-body interactions in a double-well potential

Nana Chang, Zi-Fa Yu, Ai‐Xia Zhang +1 more

We investigate the tunneling dynamics of a few bosons with both two- and three-body interactions in a doublewell potential. Uncorrelated tunneling of Rabi oscillation with the minimum period can happen only when the two- and three-body interactions satisfy a critical condition, i.e., the effective interaction energy is minimized. When the atomic interactions are slightly away from the critical condition in the weak interaction regime, the uncorrelated tunneling exhibits collapse-revival character. When the atomic interactions are strong and far away from the critical condition, the correlated tunneling with Rabi oscillation occurs. The tunneling period (the period of collapse-revival) increases (decreases) when the rate between the two-body and three-body interactions is away from the corresponding critical condition or when the number of bosons increases. Further, the tunneling properties are understood with the help of the energy spectrum of the system. Eventually, the effect of the initial configuration on the tunneling dynamics of a few bosons for both odd and even numbers of bosons is studied, which results in intriguing consequences.
