$δ'$的位势逼近:具有范数预解式收敛的逆Klauder现象

Potential approximations to $δ'$: an inverse Klauder phenomenon with norm-resolvent convergence

Pavel Exner, Hagen Neidhardt, Valentin Zagrebnov

摘要:

我们证明了存在一族具有标度势的Schroedinger算子,它在范数预解式意义下近似于$δ'$ -相互作用哈密顿量。这种近似,基于Cheon和Shigehara提出的正式计划,具有非平凡的收敛性质,在几个方面与Klauder现象相反。

英文摘要:

We show that there is a family Schroedinger operators with scaled potentials which approximates the $δ'$-interaction Hamiltonian in the norm-resolvent sense. This approximation, based on a formal scheme proposed by Cheon and Shigehara, has nontrivial convergence properties which are in several respects opposite to those of the Klauder phenomenon.
