  We investigate the ground state properties and tunneling dynamics of
ultracold dipolar bosons in a one dimensional triple well trap from a few-body
ab-initio perspective. Our focus is primarily on the distinctive features of
dipolar bosons compared to the contact interacting bosons. Formation of
intra-well localization is observed for very strong dipolar interaction.
General population rearangement as well as fragmentation and localization
effects have been found, depending strongly on the particle number. The energy
spectrum for two particles exhibits avoided crossings that lead to several
distinct resonances involving different bands, i.e. to an inter-band resonant
tunneling dynamics. The corresponding mechanisms are investigated by studying
among others the pair-probability and performing an eigenstate analysis.
