Resonances in Models of Spin Dependent Point Interactions
Claudio Cacciapuoti, Raffaele Carlone, Rodolfo Figari
In dimension we define a family of two-channel Hamiltonians obtained as point perturbations of the generator of the free decoupled dynamics. Within the family we choose t…

Spin dependent point potentials in one and three dimensions
Claudio Cacciapuoti, Raffaele Carlone, Rodolfo Figari
We consider a system realized with one spinless quantum particle and an array of spins 1/2 in dimension one and three. We characterize all the Hamiltonians obtained as point pe…
