Virial expansion coefficients in the harmonic approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
The virial expansion method is applied within a harmonic approximation to an interacting N-body system of identical fermions. We compute the canonical partition functions for two a…

Many-particle Systems in One Dimension in the Harmonic Approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
We consider energetics and structural properties of a many particle system in one dimension with pairwise contact interactions confined in a parabolic external potential. To render…
