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…
Dynamics of entanglement entropy of interacting fermions in a 1D driven harmonic trap
J. R. McKenney, W. J. Porter, J. E. Drut
Following up on a recent analysis of two cold atoms in a time-dependent harmonic trap in one dimension, we explore the entanglement entropy of two and three fermions in the same si…
Pion structure function from leading neutron electroproduction and SU(2) flavor asymmetry
J. R. McKenney, Nobuo Sato, W. Melnitchouk +1
We examine the efficacy of pion exchange models to simultaneously describe leading neutron electroproduction at HERA and the flavor asymmetry in the proton. A det…
Ground-state energy, density profiles, and momentum distribution of attractively interacting 1D Fermi gases with hard-wall boundaries: a Monte Carlo study
J. R. McKenney, C. R. Shill, W. J. Porter +1
Motivated by the realization of hard-wall boundary conditions in experiments with ultracold atoms, we investigate the ground-state properties of spin-1/2 fermions with attractive i…
