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…
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…
Virial expansion for the Tan contact and Beth-Uhlenbeck formula from 2D SO(2,1) anomalies
Wilder S. Daza, Joaquín E. Drut, Chris L. Lin +1
The relationship between 2D conformal anomalies in nonrelativistic systems and the virial expansion is explored using recently developed path-integral methods. In the pro…
