    "abstract": "We analyze the quantum entanglement between two interacting atoms trapped in\na spherical harmonic potential. At ultra-cold temperature, ground state\nentanglement is generated by the dominated s-wave interaction. Based on a\nregularized pseudo-potential Hamiltonian, we examine the quantum entanglement\nby performing the Schmidt decomposition of low-energy eigenfunctions. We\nindicate how the atoms are paired and quantify the entanglement as a function\nof a modified s-wave scattering length inside the trap.",
