A theorem stating that the energy eigenstates for an electron in a crystal can be written as Bloch waves. (name) This follows from theorem 3.3ii. ii. Since the trace is the sum of the eigenvalues, we also have tr(B) = ρ1 +ρ2 +···+ρn. (3.31) iii. The characteristic exponents are not unique since if ρj = eµjT, then ρj = e(µj+2πi/T)T.

Bloch theorem

The Bloch theorem is a powerful theorem stating that the expectation value of the U(1) current operator averaged over the entire space vanishes in large quantum systems. Note that Bloch’s theorem • is true for any particle propagating in a lattice (even though Bloch’s theorem is traditionally stated in terms of electron states (as above), in the derivation we made no assumptions about what the particle was); • makes no assumptions about the … PHYSICAL REVIEW B 91, 125424 (2015) Generalized Bloch theorem and topological characterization E.

Johnson and J. D.
