Corrections: (i) at 46:26, the figure may give the impression that at the top level, states with both +k and -k are occupied; they are not. Only states with +k are occupied. Note that this is taken care of when writing D(E) in terms of D(k) because we do not multiply by 2 (for +k and -k) and take D(k) = L/(2*pi) in doing so; (ii) at 51:20 G is 2e^2/h *(an integer) is not argued correctly. It is explained properly a little later. • Metal clusters and explanation for magic clusters are discussed. Then Coulomb blockade in mesoscopic system is described and explained. Finally, quantization of conductance in a strip of wire connected between two reservoirs is discussed. • References: (i) Chapter 18 (first four sections): Kittel • (ii) Knight et al., Phys. Rev.
