Abstract	:	Impurities have a wide range of effects in interacting quantum many-body sys-tems. They can interplay with interactions and lead to new electronic states of matter.They can also serve as a probe of an "intrinsic" many-body system. In this thesis,we consider the effects of impurities in three quantum many-body systems. First,we study the transport properties of a two-diinensional intemcting electronic systemwith dilute quenched disorder. We find that, the ground state is in fact a metallicstate and in-plane magnetic-field can drive it to an insulating one. Second, we addressthe orthogonality catastrophe in Bose-Einstein....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
