Domain Wall

A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. It can take on different meanings depending on the context:

  • Domain wall (magnetism), an interface separating magnetic domains
  • Domain wall (optics), for domain walls in optics
  • Domain wall (string theory), a theoretical 2-dimensional singularity

Famous quotes containing the words wall and/or domain:

    ... the Wall became a magnet for citizens of every generation, class, race, and relationship to the war perhaps because it is the only great public monument that allows the anesthetized holes in the heart to fill with a truly national grief.
    Adrienne Rich (b. 1929)

    No domain of nature is quite closed to man at all times.
    Henry David Thoreau (1817–1862)
