In a wide class of D-dimensional spacetimes which are direct or semi-direct sums of a (D−n)-dimensional space and an n-dimensional homogeneous “internal” space, a field can be decomposed into modes. As a result of this mode decomposition, the main objects which characterize the free quantum field, such as Green functions and heat kernels, can effectively be… CONTINUE READING
