摘要

被困在二维空间并受谐波约束势约束的离子具有广泛变化的定态，这些定态表现出各种渐近形式和分岔。我们提出了N = 2至5离子的这些结构的鸟瞰图，以及各向异性的全范围。这些结果可以使用这里提供的软件进行详细的查询。还确定了分岔点和极限处的能量变化;对于N = 5，这些包括蓝天(或鞍节点)分岔。对于更大的离子系统，即N = 10，也进行了有限的探索。

Equilibrium states of confined ions in two dimensions

ABSTRACT Ions that are trapped in two dimensions and are subject to a harmonic confining potential have widely varying stationary states that exhibit various asymptotic forms and bifurcations. We present a ‘birds-eye’ view of these structures for N = 2 to 5 ions, and the full range of anisotropy. These results may be interrogated in detail using the software provided here. Energy variations at bifurcation points and limits are also identified; for N = 5 these include blue-sky (or saddle-node) bifurcations. A limited attempt is also made to explore such features for a larger system of ions, i.e. N = 10.
