Supersymmetric Extensions of Calogero--Moser--Sutherland like Models: Construction and Some Solutions

Heiner Kohler, Thomas Guhr

摘要:

我们介绍了一类新的模型相互作用的粒子。我们的构造是基于某些超空间上径向坐标的雅可比行列式。由此产生的模型包含两个参数,确定相互作用的强度。这扩展和推广的Calogero-Moser-Sutherland型模型的相互作用粒子在普通的空间。后者作为特例包含在我们的模型中。利用我们以前对超空间中的球函数所得到的结果,我们得到了解的各种性质和一些显式形式。我们提出物理解释。我们的模型涉及两种相互作用的粒子。其中一个模型可以看作是描述一维半导体的上下能带中的相互作用电子。另一种模型是准二维的。两种粒子被限制在两个不同的空间方向,相互作用包含偶极-偶极力或张量力。

英文摘要:

We introduce a new class of models for interacting particles. Our construction is based on Jacobians for the radial coordinates on certain superspaces. The resulting models contain two parameters determining the strengths of the interactions. This extends and generalizes the models of the Calogero--Moser--Sutherland type for interacting particles in ordinary spaces. The latter ones are included in our models as special cases. Using results which we obtained previously for spherical functions in superspaces, we obtain various properties and some explicit forms for the solutions. We present physical interpretations. Our models involve two kinds of interacting particles. One of the models can be viewed as describing interacting electrons in a lower and upper band of a one--dimensional semiconductor. Another model is quasi--two--dimensional. Two kinds of particles are confined to two different spatial directions, the interaction contains dipole--dipole or tensor forces.
