Variational Theory of Quantum Fluids.
Abstract
A theory is developed to allow the systematic calculation of the properties of quantum fluids given the microscopic two body potential. Physical arguments are used to construct a correlation operator that approximately transforms the states of a noninteracting system into the corresponding states of the interacting system. The theory is regarded as a microscopic realization of Landau's assumption of a one to one correspondence between the noninteracting and interacting states. A survey of various other many body theories are discussed. The Fermi hypernetted chain integral equations are generalized to allow the calculation of E (pi) in Fermi systems, using the correlation operator wave function. The method is applied to liquid He3 and the v sub 2 model of nuclear matter.
