Partial Fermionization---Spectral Universality in 1D Repulsive Bose Gases

By Quirin Hummel and others
Due to the vast growth of the many-body level density with excitation energy, its smoothed form is of central relevance for spectral and thermodynamic properties of interacting quantum systems. We compute the cumulative of this level density for confined one-dimensional continuous systems with repulsive short-range interactions. We show that the... Show more
