一维和三维中的自旋相关点势

Spin dependent point potentials in one and three dimensions

Claudio Cacciapuoti, Raffaele Carlone, Rodolfo Figari

摘要:

我们考虑一个系统实现了一个无自旋量子粒子和一个阵列的$N$自旋1/2的一维和三维。我们的特点是所有的哈密顿作为点扰动的指定的自由动力学的一些“广义边界条件”。对于每一个边界条件,我们给出了相应的哈密顿量的预解式的显式公式。我们讨论了局部性的问题,并给出了两个例子的自旋相关的点势,可能是多组分可解模型的兴趣。

英文摘要:

We consider a system realized with one spinless quantum particle and an array of $N$ spins 1/2 in dimension one and three. We characterize all the Hamiltonians obtained as point perturbations of an assigned free dynamics in terms of some ``generalized boundary conditions''. For every boundary condition we give the explicit formula for the resolvent of the corresponding Hamiltonian. We discuss the problem of locality and give two examples of spin dependent point potentials that could be of interest as multi-component solvable models.
