Eigenvalues and Eigenfunctions of a Bose System of Hard Spheres and Its Low-Temperature Properties
T. D. Lee, Kerson Huang, Chongming Yang
It is shown that the pseudopotential method can be used for an explicit calculation of the first few terms in an expansion in power of ${(\ensuremath{\rho}{a}^{3})}^{\frac{1}{2}}$ of the eigenvalues and the corresponding eigenfunctions of a system of Bose particles with hard-sphere interaction. The low-temperature properties of the system are discussed.
