Domain may refer to:
A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model. Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is the metastable vacuum.
A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.
Important examples are:
Besides these important cases similar solitons appear in wide spectrum of the models. Here are other examples:
Domain is a German power metal band.
Domain first impressed fans of melodic metal back in the 1980s with their first works, "Lost In The City" (still under the old band name Kingdom), "Before The Storm" and "Crack in The Wall", as well as with their hit songs such as 'Lost In The City' and ‚ 'I Don’t Wanna Die'. Single "Heart Of Stone was a title song of german mini-serial "Bastard".
But it was their next albums, "One Million Lightyears From Home" (2001), "The Artefact" (2002) and "The Sixth Dimension" (2003) as well as a successful tour with the rock legends, Glenn Hughes and Joe Lynn Turner (HTP) that secured the quintet a place in the European Melodic Metal scene. With a harder edged sound, Domain still had a good following. And that was when the career of the guitarist Axel "Ironfinger" Ritt (Grave Digger), ex-vocalist Carsten Lizard Schulz (Evidence One et al.), and the long-term band mates keyboarder Erdmann Lange, ex-bass player Jochen Mayer (Boysvoice, Demon Drive, Casanova) and the ex-drummer Stefan Köllner really began…
I'm spending my days, they rush like a stream
With a girl by my side, my life seems like a dream
Some storm under surface, it breaks out like hell
People spreading ideas like they're under a spell
And as I'm understanding,
Just what it is, they're preaching
Finally I'm realizing,
It's my life, that they are teaching!
I can't fight flames, it's burning like hell
I can't stop this Great Rebellion
Like a spark to a flame, a virus of my name
I started this Great Rebellion
It's time for some new days, reach higher and higher
There must be life beyond beauty
Let's explore some new ways, some' new to desire
There must be life beyond beauty
Faster than bullets, they spread the disease
A world flamed with anger, not harmony and peace
It's gods against men, it's young against old
And it's growing much stronger, with the stories, I've told
And as I'm understanding,
Just what it is that they're preaching
Finally I'm realizing,
It is my life, they are teaching!
I can't fight flames, it's burning like hell
I can't stop this Great Rebellion
Like a spark to a flame, a virus of my name
I started this Great Rebellion
It's time for some new days, reach higher and higher
There must be life beyond beauty
Let's explore some new ways, some' new to desire
There must be life beyond beauty
