میدان ِ مرپلی meydân-e marpeli
*Fr.: champ scalaire*
A → *field* whose value at every point of space is independent of
→ *direction* and → *position*.
Examples include → *temperature* distribution throughout space
and → *pressure* distribution in a → *fluid*.
Similarly, a → *potential field*, such as the Newtonian
→ *gravitational field* or the electric potential in
→ *electrostatics* are scalar fields.
In quantum field theory, a scalar field is associated with → *spin*
zero particles, such as → *meson*s or → *boson*s.
Therefore, the → *Higgs boson* is associated with
a scalar field. The → *derivative*
of a scalar field results in a → *vector field*
is called the
→ *gradient*.
In contrast to a vector field, a scalar field is → *invariant*
under the → *rotation* of the
→ *coordinate system*.
The → *inflation*
in the → *early Universe* is supposed to be driven by
a scalar field, called the → *inflaton field*. → *scalar*; → *field*. |
