On a comparison between absolute and relative self-adjoint extension schemes
Noè Angelo Caruso, Alessandro Michelangeli, Andrea Ottolini
The problem of connecting the operator parameters that label the same self-adjoint extension of a given symmetric operator, respectively, within the 'absolute' von Neumann extensio…
On the characterisation of fragmented Bose-Einstein condensation and its emergent effective evolution
Jinyeop Lee, Alessandro Michelangeli
Fragmented Bose-Einstein condensates are large systems of identical bosons displaying \emph{multiple} macroscopic occupations of one-body states, in a suitable sense. The quest for…
Generalised solutions to linear and non-linear Schrödinger-type equations with point defect: Colombeau and non-Colombeau regimes
N. Dugandžija, A. Michelangeli, I. Vojnović
For a semi-linear Schrödinger equation of Hartree type in three spatial dimensions, various approximations of singular, point-like perturbations are considered, in the form of pote…
Standing waves and global well-posedness for the 2d Hartree equation with a point interaction
Vladimir Georgiev, Alessandro Michelangeli, Raffaele Scandone
We study a class of two-dimensional non-linear Schrödinger equations with point-like singular perturbation and Hartree non-linearity. The point-like singular perturbation of the fr…
Self-adjoint extension schemes and modern applications to quantum Hamiltonians
Matteo Gallone, Alessandro Michelangeli
This monograph contains revised and enlarged materials from previous lecture notes of undergraduate and graduate courses and seminars delivered by both authors over the last years…
