对于一个系统来说?相互作用的粒子在 “齐次”势的背景,我们证明如果 单粒子哈密顿量允许状态密度,相互作用的粒子哈密顿量也是如此。此外,这种状态的综合密度 与自由粒子哈密顿量的结果一致。对于 相互作用的粒子安德森模型,我们证明了正则性 通过建立一个完整的态密度来研究其性质 韦格纳估计。
For a system of ? interacting particles moving in the background of a “homogeneous” potential, we show that if the single particle Hamiltonian admits a density of states, so does the interacting ? -particle Hamiltonian. Moreover, this integrated density of states coincides with that of the free particle Hamiltonian. For the interacting ? -particle Anderson model, we prove regularity properties of the integrated density of states by establishing a Wegner estimate.
