In the present work, the effect of dust polarization force on different low-frequency dust modes is investigated in ultra-cold quantum dusty plasma. The quantum hydrodynamic model has been employed for electron, ion and charged dust species and the analysis has been done using the normal mode technique. It is observed that the dispersion relation of low-frequency dust modes significantly modified due to the inclusion of polarization force, neutral particles and quantum correction. The numerical analysis has also been presented to see the effect of dust polarization force on dispersion properties of different low-frequency modes. The phase speed of each mode is found to be modified due to the polarization force.
