This is a one-electron Hamiltonian which has the periodicity of the lattice. H = p2 2m +V(r). (1.1) If R is a translation vector of the lattice, then V(r) = V(r + R). To of the Bloch electrons is the formation of energy band (allowed energy regions) and band gap (forbidden energy region). In this note we discuss the Bloch theorem using the concept of the translation operator, the parity operator, and the time-reversal operator in quantum mechanics.

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 strength of the potential. 7You can check that u j,q

In the present paper we analyze the possibility that this theorem remains valid within quantum field theory relevant for the description of both high energy physics and condensed matter physics phenomena. First of all, we prove that the total electric current in equilibrium is the Bloch theorem.

Attention is called to a theorem of Bloch, from which it is shown that even when interelectronic interactions are taken into account, the state of lowest electronic free energy corresponds to a zero net current. This result contradicts the hypothesis that superconductivity is caused by spontaneous currents.

However, Bloch’s Theorem proves that if V has translational symmetry, the solutions can be written The electrons are no longer free electrons, but are now called Bloch electrons. Bloch’s theorem Theorem: The eigenstates of the Hamitonian Hˆ above can be chosen to have the form of a plane wave times a function with the periodicity of the Bravais lattice: nk(r) = eikru nk(r) where u nk(r+ R) = u nk(r) Statement of Bloch theorem: Bloch theorem states that, the solutions of Schrödinger wave equation for an electron. moving in a periodic potential are the plane waves modulated by a function having the same periodicity as that of the. lattice. Bloch theorem. In a crystalline solid, the potential experienced by an electron is periodic. V (x) = V (x +a) V ( x) = V ( x + a) where a is the crystal period/ lattice constant.
