    "abstract": "We present a theory that accurately describes the counting of excited states\nof a noninteracting fermionic gas. At high excitation energies the results\nreproduce Bethe\u0027s theory. At low energies oscillatory corrections to the\nmany--body density of states, related to shell effects, are obtained. The\nfluctuations depend non-trivially on energy and particle number. Universality\nand connections with Poisson statistics and random matrix theory are\nestablished for regular and chaotic single--particle motion.",
