field
physical quantity, represented by a number or tensor, that has a value for each point in space-time
dark energy
repulsive property with constant energy density theorized to make up most of the universe’s energy content to account for its observed expansion
flow velocity
vector field which is used to mathematically describe the motion of a continuum
source field
type of field appearing in the Lagrangian
potential
in mathematics and physics, field defined in space, from which many important physical properties may be derived
magnetic field strength
strength of a magnetic field
electromagnetic field
physical field produced by electrically charged objects
electric field
spatial distribution of vectors representing the force applied to a charged test particle
vector field
assignment of a vector to each point in a subset of Euclidean space
superfield
field defined on a superspace describing a supermultiplet on real spacetime
dual graviton
dualization of the (linearized) gravitational field under electric–magnetic duality
Near and far field
regarding radioantennas
ghost field
fields without physical meaning to introduce mathematical consistency
magnetic field
spatial distribution of vectors allowing the calculation of the magnetic force on a test particle
scalar field
assignment of numbers to points in space
force field
physics term
tensor field
assignment of a tensor continuously varying across a mathematical space
auxiliary field
field in a classical or quantum field theory that has a trivial equation of motion, with no independent propagating degrees of freedom, which can be therefore substituted away in favor of other fields
synthetic gauge field
effective gauge field which, by experimental design, affects the dynamics of atoms in ultracold quantum gases
