WebDec 6, 2024 · To track the transfer of spectral weight, the initial (photoinjected) states and final states must be unambiguously defined and located. This is easiest on a small Fermi surface, such as that of graphene, where phase-space scattering restrictions limit the number of initial and final states. WebWeight transfer is generally of far less practical importance than load transfer, for cars and SUVs at least. For instance in a 0.9g turn, a car with a track of 1650 mm and a CoM height of 550 mm will see a load transfer of 30% of the vehicle weight, that is the outer wheels will see 60% more load than before, and the inners 60% less.
