      abstract     = {We present transport measurements on high-mobility bilayer
                      graphene fully encapsulated in hexagonal boron nitride. We
                      show two terminal quantum Hall effect measurements which
                      exhibit full symmetry broken Landau levels at low magnetic
                      fields. From weak localization measurements, we extract
                      gate-tunable phase-coherence times τϕ as well as the
                      inter- and intravalley scattering times τi and τ∗,
                      respectively. While τϕ is in qualitative agreement with an
                      electron-electron interaction-mediated dephasing mechanism,
                      electron spin-flip scattering processes are limiting τϕ at
                      low temperatures. The analysis of τi and τ∗ points to
                      local strain fluctuation as the most probable mechanism for
                      limiting the mobility in high-quality bilayer graphene.},
