环上的玻色子和费米子偶极子

Bosonic and fermionic dipoles on a ring

Sascha Zöllner, G. M. Bruun, C. J. Pethick, S. M. Reimann

摘要:

我们发现,偶极玻色子和费米子被限制在一个准一维的环形陷阱表现出丰富的各种状态,因为他们的相互作用是不均匀的。对于纯排斥相互作用,随着偶极耦合强度的增加,存在从气体状状态到非均匀晶体状状态的交叉。对于偶极和环平面之间足够小的角度,存在具有吸引相互作用的区域,并且可以形成聚集态。

英文摘要:

We show that dipolar bosons and fermions confined in a quasi-one-dimensional ring trap exhibit a rich variety of states because their interaction is inhomogeneous. For purely repulsive interactions, with increasing strength of the dipolar coupling there is a crossover from a gas-like state to an inhomogeneous crystal-like one. For small enough angles between the dipoles and the plane of the ring, there are regions with attractive interactions, and clustered states can form.
