圆上二面角系的Action -角变量

Action-angle variables for dihedral systems on the circle

Olaf Lechtenfeld, Armen Nersessian, Vahagn Yeghikyan

摘要:

一个在圆上的非相对论性粒子,其势为cos^{-2}(k φ),它与二维(二面角)Coxeter系统I_2(k)有关,其中k为N。对于这样的“二面角系统”,我们构建的作用角变量,并建立一个本地等价的一个自由粒子上的圆。我们在作用角变量中对这些系统进行量子化,并讨论了这个过程的超对称扩展。通过允许径向运动,我们得到了相关的二维系统,包括R上的A_2、BC_2和G_2三粒子有理Calogero模型,并对它们进行了分析。

英文摘要:

A nonrelativistic particle on a circle and subject to a cos^{-2}(k phi) potential is related to the two-dimensional (dihedral) Coxeter system I_2(k), for k in N. For such `dihedral systems' we construct the action-angle variables and establish a local equivalence with a free particle on the circle. We perform the quantization of these systems in the action-angle variables and discuss the supersymmetric extension of this procedure. By allowing radial motion one obtains related two-dimensional systems, including A_2, BC_2 and G_2 three-particle rational Calogero models on R, which we also analyze.
