Abstract
We propose to study the ground state properties the quench dynamics of the interacting bosons in optical lattice both for the deep and shallow. The usage of optical lattice of different height will allow us to study the whole regime of a single condensate to fragmented condensate. Moreover we shall demonstrate the fundamental correlation between the production of entropy, build up of correlation and loss of coherence in the system. As the correlation and coherence are now experimentally accessible, their connection to many-body entropies can be scrutinized to detect statistical relaxation and to prove the eigenstate thermalization hypothesis (ETH). We will utilize the recent recursive software implementation of the MCTDHB. (AU)
