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…

Quantum anomaly and thermodynamics of one-dimensional fermions with antisymmetric two-body interactions
Horacio E. Camblong, Abhijit Chakraborty, Wilder S. Daza +3
A system of two-species, one-dimensional fermions, with an attractive two-body interaction of the derivative-delta type, features a scale anomaly. In contrast to the well-known two…
