“…By citing [1] it is important to recall that 'as is well known to Quantum Chemistry students, three-dimensional interactions with a nonzero range do not manifest this singular behavior in the limit of the distance between the two centers shrinking to zero, as the classical textbook example of H + 2 smoothly approaching He + in the limit R → 0 + clearly shows' (see [2][3][4]). The same phenomenon had been observed in [5] (see also [6][7][8][9][10]) dealing with another model involving a pair of identical point interactions symmetrically situated around the origin defined rigorously by using a 'coupling constant renormalization' as well, namely the one-dimensional energy operator in which the kinetic component is given by the Salpeter free Hamiltonian p 2 + m 2 , m > 0.…”

“…As can be guessed, the proof is bound to be rather similar to the one of Theorem 2.2(b) in [10] for the one-dimensional analog of the model since the behavior of the following series will play a crucial role:…”

“…In this work, we wish to further extend our previous research on various types of point perturbations of Schrödinger Hamiltonians with or without harmonic confinement (see, e.g., [2][3][4][5][6][7][8][9][10][11]) to the physical models utilized to describe three-dimensional quantum dots.…”
