Abstract

Within the framework of quantum mechanics working with one-dimensional, manifestly non-Hermitian Hamiltonians H=T+VH=T+V the traditional class of the exactly solvable models with local point interactions V=V(x)V=V(x) is generalized. The consequences of the use of the nonlocal point interactions such that (Vf)(x)=K(x,s)f(s)ds(V f)(x) = \int K(x,s) f(s) ds are discussed using the suitably adapted formalism of boundary triplets.
