Energetic and Structural Properties of Two-Dimensional Trapped Mesoscopic Fermi Gases
Emma K. Laird, Brendan C. Mulkerin, Jia Wang +1
We theoretically investigate equal-mass spin-balanced two-component Fermi gases in which pairs of atoms with opposite spins interact via a short-range isotropic model potential. We…

Hyperspherical Analysis of Dimer-Dimer Scattering in One-Dimensional Systems
Jia Wang, Hui Hu, Xia-Ji Liu
We present a comprehensive analysis of four-body scattering in one-dimensional (1D) quantum systems using the adiabatic hyperspherical representation (AHR). Focusing on dimer-dimer…

Exact spectral properties of Fermi polarons in one-dimensional lattices: Anomalous Fermi singularities and polaron quasiparticles
Hui Hu, Jia Wang, Xia-Ji Liu
We calculate the exact spectral function of a single impurity repulsively interacting with a bath of fermions in one-dimensional lattices, by deriving the explicit expression of th…
