Coupling and particle number intertwiners in the Calogero model
Francisco Correa, Luis Inzunza, Olaf Lechtenfeld
It is long known that quantum Calogero models feature intertwining operators, which increase or decrease the coupling constant by an integer amount, for any fixed number of particl…

The tetrahexahedric angular Calogero model
Francisco Correa, Olaf Lechtenfeld
The spherical reduction of the rational Calogero model (of type and after removing the center of mass) is considered as a maximally superintegrable quantum system, which…
