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…
A Quantum Field-Theoretical Perspective on Scale Anomalies in 1D systems with Three-Body Interactions
Wilder S. Daza, Joaquín E. Drut, Chris L. Lin +1
We analyze, from a canonical quantum field theory perspective, the problem of one-dimensional particles with three-body attractive interactions, which was recently shown to exhibit…
Quantum anomaly and thermodynamics of one-dimensional fermions with three-body interactions
Joaquín E. Drut, Joshua R. McKenney, Wilder S. Daza +2
We show that a system of three species of one-dimensional fermions, with an attractive three-body contact interaction, features a scale anomaly directly related to the anomaly of t…
