A surname.

(physics) A theorem stating that the energy eigenstates for an electron in a crystal can be written as Bloch waves.

(mathematics) A theorem that gives a lower bound on the size of a disc in which an inverse to a holomorphic function exists.

A narrow transition region at the boundary between magnetic domains, over which the magnetization changes from its value in one domain to that in the next.

(physics) In solid-state physics, the oscillation of a particle (e.g. an electron) confined in a periodic potential when a constant force is acting on it.

(quantum mechanics) A concept relating to energy spectra. Let H be the one-dimensional Schrödinger equation operator H=-(d²)/(dx²)+U_𝛼, where U_α is a periodic function of period α. The Bloch spectrum of H is the set of values E for which all the solutions of (H − E)φ = 0 are bounded on the whole real axis.

(mathematics) The space, denoted by ℬ or ℬ, of holomorphic functions f defined on the open unit disc D in the complex plane, such that the function (1-|z|²)|f^′(z)| is bounded.

plural of Bloch function

(mathematics) Any of the elements of the Bloch space.
