A novel approach to perturbative calculations for a large class of interacting boson theories
Kamil Bradler
We present a method of calculating the interacting S-matrix to an arbitrary perturbative order for a large class of boson interaction Lagrangians. The method takes advantage of a p…

Unitary evolution of a pair of Unruh-DeWitt detectors calculated efficiently to an arbitrary perturbative order
Kamil Bradler
Unruh-DeWitt Hamiltonian couples a scalar field with a two-level atom serving as a particle detector model. Two such detectors held by different observers following general traject…
