You should offer how you derive the answer from each question in
detail. If you only give the word explanation, I'll give a thumb
down.
A. Please extend to 1D nearest neighbor (n.n) Tighter Binding
(TB) to 2D square lattice. (i) obtain E(kx,ky) (ii) obtain m* for
(1,0), (0,1), (2,1) directions.
B. Please extend problem 1 to next nearest neighbor (n.n.n)
hopping. i.e., n.n. and n.n.n hopping are included. (i) obtain
E(kx,ky) in terms of parameter Tn.n. and Tn.n.n (ii) obtain m* for
(1,0), (0,1), (2,1) directions.
