Next to the harmonic oscillator and the Coulomb potential the class of two-body models with point interactions is the only one where complete solutions are avai

Exactly solvable models, that is, models with explicitly and completely diagonalizable Hamiltonians are too few in number and insufficiently diverse to meet the

Exactly Solved Models in Statistical Mechanics

This book investigates two possibilities for describing classical-mechanical physical systems along with their Hamiltonian dynamics in the framework of quantum

Exactly solvable models are very important in physics from a theoretical point of view and also from the experimentalist's perspective, because in such cases th
