Blochsfääri
Blochsfääri is a theoretical concept used in quantum mechanics, specifically in the description of electrons in periodic potentials, such as those found in crystals. It represents the state of an electron in a crystal lattice. Mathematically, a Bloch wave is characterized by a wave vector k and a crystal momentum. The Bloch sphere is a generalization of the Bloch sphere used for spin-1/2 particles, which is a simple sphere. For systems with more complex internal degrees of freedom, the Bloch sphere can become a more complex manifold.
The Bloch sphere is a geometrical representation of the possible quantum states of a two-level system, also
In the context of solids, Bloch's theorem states that the wave function of an electron in a
