Finite-momentum superconductivity with singlet-triplet mixing in an altermagnetic metal: A pairing instability analysis
Hui Hu, Zhao Liu, Jia Wang +2
We analyze the pairing instability of an altermagnetic metal on a square lattice driven by an attractive nearest-neighbor interaction. This interaction enables multiple pairing cha…
Properties of Bose-Einstein condensates with altermagnetism
Jia Wang, Zhao Liu, Xia-Ji Liu +1
We investigate a weakly interacting two-component Bose--Einstein condensate in the miscible regime in the presence of \emph{altermagnetism}, i.e., a collinear and globally compensa…
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…
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…
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…
