耗散光晶格中的自组织

Self-organization in dissipative optical lattices

G. Baris Bagci, Ugur Tirnakli

摘要:

我们表明,从高斯到q-高斯分布发生在耗散光晶格中的原子输运的过渡可以被解释为自组织求助于一个修改版本的Klimontovich的S-定理。结果发现,只有在二阶矩<p^{2}>有限的情况下,自组织在过渡区才是可能的。因此,非加性参数q被限制在1<q<5/3的范围内,尽管q值的整个谱,即,1<q<3,理论上是可能的。从修正的S-定理获得的q值的范围也由Douglas等人进行的实验证实。96,110601(2006)]。

英文摘要:

We show that the transition from Gaussian to the q-Gaussian distributions occurring in atomic transport in dissipative optical lattices can be interpreted as self-organization by recourse to a modified version of Klimontovich's S-theorem. As a result, we find that self-organization is possible in the transition regime, only where the second moment <p^{2}> is finite. Therefore, the nonadditivity parameter q is confined within the range 1<q<5/3, although whole spectrum of q values i.e., 1<q<3, is considered theoretically possible. The range of q values obtained from the modified S-theorem is also confirmed by the experiments carried out by Douglas et al. [Phys. Rev. Lett. 96, 110601 (2006)].
