  • Bloch wave — A Bloch wave or Bloch state, named after Felix Bloch, is the wavefunction of a particle (usually, an electron) placed in a periodic potential. It consists of the product of a plane wave envelope function and a periodic function ( periodic Bloch… …   Wikipedia

  • Bloch's theorem (complex variables) — Bloch s theorem, named after André Bloch is as follows.Let f be a holomorphic function on a region (i.e. an open, connected subset of C) that includes as a subset the closed unit disk | z | le; 1. Suppose f (0) = 0 and f prime;(0) = 1. Then for… …   Wikipedia

  • Bloch oscillations — Bloch oscillation is a phenomenon from solid state physics. It describes the oscillation of a particle (e.g. an electron) if a constant force is acting on it.If a particle is exposed to a constant force its momentum changes due to Newton s law… …   Wikipedia

  • Bloch equations — underconstruction. In physics and chemistry, specifically in NMR (nuclear magnetic resonance) or MRI (magnetic resonance imaging), or ESR (electron spin resonance) the Bloch equations are a set of macroscopic equations that are used to calculate… …   Wikipedia
