Effective pair potential in the lattice Fermi gas
Description
An effective pair potential for a quantum mechanical lattice model of fermions interacting with two infinitely massive nuclei is derived exactly. A relation between the nucleus-nucleus potential and random walk generating functions is obtained by using the Trotter product formula. The detailed analysis of the pair potential for neighbour sites shows that there exist various possibilities to construct a nuclear sublattice kept by the effective interaction between nuclei
