In this talk, I shall discuss the ground state phase diagram of an experimentally realizable one-dimensional constrained dipole boson model. I shall demonstrate the presence of a many-body localized phase in the presence of an Aubry-Andre (AA) potential whose strength λ0 can be changed to tune an ergodic-MBL transition. I shall discuss the significance of such a transition in the quantum dynamics of the model by computing its response subsequent to a sudden quench of λ0. I shall also show that the MBL and the ergodic phases can be clearly distinguished by the study of post-quench dynamics and provide an estimate for minimal time up to which experiments need to track the response of the system to confirm the onset of the MBL phase. Shall suggest experiments which can test our theory.
