超对称性与两类相互作用粒子的模型
Supersymmetry and Models for Two Kinds of Interacting Particles
摘要:
我们表明,Calogero-Sutherland模型的相互作用粒子有一个自然的超对称扩展。对于构造,我们使用出现在某些超空间中的雅可比行列式。一些由此产生的哈密顿量有一个直接的物理解释,作为两种相互作用粒子的模型。一个模型可以用来描述在准一维半导体的上下能带中的相互作用电子,另一个模型对应于被限制在两个不同空间方向上的两种粒子,其相互作用涉及张量力。
英文摘要:
We show that Calogero-Sutherland models for interacting particles have a natural supersymmetric extension. For the construction, we use Jacobians which appear in certain superspaces. Some of the resulting Hamiltonians have a direct physics interpretation as models for two kinds of interacting particles. One model may serve to describe interacting electrons in a lower and upper band of a quasi-one-dimensional semiconductor, another model corresponds to two kinds of particles confined to two different spatial directions with an interaction involving tensor forces.
