Non-Commutative Field Theory |
In General > s.a. non-commutative geometry;
energy-momentum tensor; lattice
field theory [including fermion doubling]; types of field theories.
* Idea: In principle,
quantize the manifold underlying a field theory (spacetime or space)
by replacing it with a non-commutative matrix model or a "fuzzy
manifold"; In practice, replace products of fields in the action
/ Hamiltonian by star products, then integrate as usual.
* Motivation: Non-commutative
spaces (spacetimes) naturally arise in some approaches to quantum gravity;
Field theories on non-commutative spacetimes come with natural regularization
parameters, while preserving their symmetries and topological features and
altogether overcoming the fermion-doubling problem.
* Particle physics: A nice
result is that, once fermions are fixed, there is no arbitrariness in the
Higgs sector; An issue is that models generally suffer from a manifestly
non-Wilsonian coupling of infrared and ultraviolet degrees of freedom known
as the "IR/UV problem".
* Result: Free κ-Minkowski
space field theory is equivalent to a relativistically invariant, non local,
free field theory on Minkowski spacetime.

Types of Theories > s.a. gauge theories [including standard
model]; GUTs; non-commutative physics;

* Different frameworks:
One can use different star products, for example the Moyal and Wick-Voros
(or normally ordered) ones.
