    "abstract": "The effect of entanglement on off-diagonal geometric phases is investigated\nin the paper. Two spin-1/2 particles in magnetic fields along the $y$ direction\nare taken as an example. Three parameters (the purity of state $r$, the mixing\nangle $\\theta$ and the relative phase $\\beta$) are chosen to characterize the\ninitial states. The nodal points at which the usual geometric phases disappear\nare calculated and illustrated as a function of the three parameters.",
