The results show deviations from the usual QED both on the classical and the quantum levels, and on both levels, the deviations depend on the parameter of space/space noncommutativity.

In the preceding chapter, the expressions for the vacuum-to-vacuum transition amplitude have been obtained. Of practical interest, however, are transitions of a system of initially free particles…

Abstract.A non-commutative version of the usual electro-weak theory is constructed. We discuss how to overcome the two major problems: (1) although we can have non-commutative U(n) (which we denote…

A bstractRecently modified gravitational theories which mimic the behaviour of dark matter, the so-called “Mimetic Dark Matter”, have been proposed. We study the consistency of such theories with…
