We present an exactly solvable Hamiltonian which consists of nearest neighbor hopping and infinite range interaction. The ground state and the thermodynamic quantities are analytically given in any dimensions. When the interaction is repulsive, the Luttinger's theorem breaks down. At half filling, w
