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…
