A new method of performing calculations in QFT is presented, in which algebraic manipulations are performed at the probability level and propagators are expressed in terms of Pauli-Jordan (commutator) and Hadamard (anti-commutator) functions. This novel approach can be made manifestly causal, with other potential advantages including avoiding infrared singularities. This method has been applied to particle scattering and 2-level Fermi atom calculations, with hopes to apply it to scenarios involving the Unruh effect and black hole geomteries.
