Virial coefficients of trapped and un-trapped three-component fermions with three-body forces in arbitrary spatial dimensions
A. J. Czejdo, J. E. Drut, Y. Hou +2
Using a coarse temporal lattice approximation, we calculate the first few terms of the virial expansion of a three-species fermion system with a three-body contact interaction in $…
Thermodynamics and static response of anomalous 1D fermions via quantum Monte Carlo in the worldline representation
J. R. McKenney, A. Jose, J. E. Drut
A system of three-species fermions in one spatial dimension (1D) with a contact three-body interaction is known to display a scale anomaly. This anomaly is identical to that of a t…
Fermi-Fermi crossover in the ground state of 1D few-body systems with anomalous three-body interactions
J. R. McKenney, J. E. Drut
In one spatial dimension, quantum systems with an attractive three-body contact interaction exhibit a scale anomaly. In this work, we examine the few-body sector for up to six part…
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…
