Hyperspherical Treatment of Strongly-Interacting Few-Fermion Systems in One Dimension
arXiv:1408.6058 · doi:10.1140/epjst/e2015-02390-2
Abstract
We examine a one-dimensional two-component fermionic system in a trap, assuming that all particles have the same mass and interact through a strong repulsive zero-range force. First we show how a simple system of three strongly interacting particles in a harmonic trap can be treated using the hyperspherical formalism. Next we discuss the behavior of the energy for the N-body system.
