Virial Expansion for a Three-Component Fermi Gas in One Dimension: The Quantum Anomaly Correspondence

Jeff Maki, Carlos R. Ordóñez

In this paper we explore the transport properties of three-component Fermi gases confined to one spatial dimension, interacting via a three-body interaction, in the high temperatur…

Spectral density, Levinson's theorem, and the extra term in the second virial coefficient for 1D delta-function potential

H. E. Camblong, A. Chakraborty, W. S. Daza +3

In contrast with the 3D result, the Beth-Uhlenbeck (BU) formula in 1D contains an extra -1/2 term. The origin of this -1/2 term is explained using a spectral density approach. To b…
