A metal can be driven to an insulating phase through distinct mechanisms. A possible way is via the Coulomb interaction, which then defines the Mott metal-insulator transition (MIT). Another possibility is the MIT driven by disorder, the so-called Anderson MIT. In this talk I will discuss the use of quantum entanglement to identify and characterize the MIT in disordered Hubbard chains with interacting fermions — thus comprising the Mott-Anderson physics [1,2].
