Hierarchy of localized many-body bound states in an interacting open lattice
Yanxia Liu, Shu Chen
We unveil the mechanism for the formation of puzzled boundary-localized bound states in a spinless fermionic open lattice with nearest-neighbor interactions. By solving the Bethe-a…
Fate of Two-Particle Bound States in the Continuum in non-Hermitian Systems
Yanxia Liu, Shu Chen
We unveil the existence of two-particle bound state in the continuum (BIC) in a one-dimensional interacting nonreciprocal lattice with a generalized boundary condition. By applying…
Two mass-imbalanced atoms in a hard-wall trap: Deep learning integrability of many-body systems
Liheng Lang, Qichen Lu, C. M. Dai +3
The study of integrable systems has led to significant advancements in our understanding of many-body physics. We design a series of numerical experiments to analyze the integrabil…
Three-body bound states of two bosons and one impurity in one dimension
Yanxia Liu, Yi-Cong Yu, Shu Chen
We investigate one-dimensional three-body systems composed of two identical bosons and one imbalanced atom (impurity) with two-body and three-body zero-range interactions. For the…
Spectroscopy and spin dynamics for strongly interacting few spinor bosons in one-dimensional traps
Yanxia Liu, Shu Chen, Yunbo Zhang
We consider a one-dimensional trapped gas of strongly interacting few spin-1 atoms which can be described by an effective spin chain Hamiltonian. Away from the SU(3) integrable poi…
Exact ordering of energy levels for one-dimensional interacting Fermi gases with symmetry
Lei Pan, Yanxia Liu, Haiping Hu +2
Based on the exact solution of one-dimensional Fermi gas systems with symmetry in a hard wall, we demonstrate that we are able to sort the ordering of the lowest energy eig…
Two Atoms in a Double Well: An Exact Solution
Yanxia Liu, Yunbo Zhang
We propose to experimentally realize an odd parity eigenstate of two atoms in the double well. The occupation probability of this state shows evident d…
Improvement of the matching of the exact solution and variational approaches in an interacting two-fermion system
Yanxia Liu, Jun Ye, Yuanyuan Li +1
A more reasonable trial ground state wave function is constructed for the relative motion of an interacting two-fermion system in a 1D harmonic potential. At the boundaries both th…
