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…
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…
Breakdown of the single-mode description of ultradilute quantum droplets in binary Bose mixtures: A perspective from a microscopic bosonic pairing theory
Hui Hu, Jia Wang, Han Pu +1
In his seminal proposal of quantum droplets in binary Bose mixtures {[}Phys. Rev. Lett. \textbf{115}, 155302 (2015){]}, Dmitry Petrov suggested that the density ratio …
When does a Fermi puddle become a Fermi sea? Emergence of pairing in two-dimensional trapped mesoscopic Fermi gases
Emma K. Laird, Brendan C. Mulkerin, Jia Wang +1
Pairing lies at the heart of superfluidity in fermionic systems. Motivated by recent experiments in mesoscopic Fermi gases, we study up to six fermionic atoms with equal masses and…
Theory of the spectral function of Fermi polarons at finite temperature
Hui Hu, Jia Wang, Xia-Ji Liu
We develop a general theory of Fermi polarons at nonzero temperature, including particle-hole excitations of the Fermi sea shake-up to arbitrarily high orders. The exact set of equ…
Exact theory of the finite-temperature spectral function of Fermi polarons with multiple particle-hole excitations: Diagrammatic theory versus Chevy ansatz
Hui Hu, Jia Wang, Xia-Ji Liu
By using both diagrammatic theory and Chevy ansatz approach, we derive an exact set of equations, which determines the spectral function of Fermi polarons with multiple particle-ho…
Super Fermi polaron and Nagaoka ferromagnetism in a two-dimesnional square lattice
Hui Hu, Jia Wang, Xia-Ji Liu
We consider the Fermi polaron problem of an impurity hopping around a two-dimensional square lattice and interacting with a sea of fermions at given filling factor. When the intera…
Thermally stable p-wave repulsive Fermi polaron without a two-body bound state
Hui Hu, Jia Wang, Xia-Ji Liu
We theoretically investigate the polaron physics of an impurity immersed in a two-dimensional Fermi sea, interacting via a p-wave interaction at finite temperature. In the unitary…
Discrete Time Crystals with Absolute Stability
Krzysztof Giergiel, Jia Wang, Bryan J. Dalton +2
We show that interacting bosons on a ring which are driven periodically by a rotating potential can support discrete time crystals whose absolute stability can be proven. The absol…
