    "abstract": "We study the generation of two-mode entanglement in a two-component\nBose-Einstein condensate trapped in a double-well potential. By applying the\nHolstein-Primakoff transformation, we show that the problem is exactly solvable\nas long as the number of excitations due to atom-atom interactions remains low.\nIn particular, the condensate constitutes a symmetric Gaussian system, thereby\nenabling its entanglement of formation to be measured directly by the\nfluctuations in the quadratures of the two constituent components [Giedke {\\it\net al.}, Phys. Rev. Lett. {\\bf 91}, 107901 (2003)]. We discover that\nsignificant two-mode squeezing occurs in the condensate if the interspecies\ninteraction is sufficiently strong, which leads to strong entanglement between\nthe two components.",
