چکیده
We analyze families of particle detector models that linearly couple to different kinds fermionic and bosonic fields. also study the response these detectors anti-particle excitations field. propose a simple linear complex scalar model captures fundamental features field similarly how Unruh-DeWitt light matter interaction. discuss why we do not need limit ourselves quadratic commonly employed in past literature. Namely, provide physically motivated mechanism restores U(1) symmetry models.

Parametric representation of “critical” noncommutative QFT models
We extend the parametric representation of renormalizable non commutative quantum field theories to a class of theories which we call “critical”, because their power counting is definitely more difficult to obtain.This class of theories is important since it includes gauge theories, which should be relevant for the quantum Hall effect.
متن کاملThree Études in QFT
We review QFT from the algebraic structure of its perturbative expansion and point out three new results. Acknowledgments It is a pleasure to thank Spencer Bloch for questions which ultimately led to Theorem 3 below. The following is a write-up of an invited contribution to the International Congress for Mathematical Physics (Prague, 2009). Thanks are due to Pavel Exner and the other organizers...
متن کاملParticle-antiparticle asymmetries from annihilations.
An extensively studied mechanism to create particle-antiparticle asymmetries is the out-of-equilibrium and CP violating decay of a heavy particle. We, instead, examine how asymmetries can arise purely from 2→2 annihilations rather than from the usual 1→2 decays and inverse decays. We review the general conditions on the reaction rates that arise from S-matrix unitarity and CPT invariance, and s...
متن کاملUnique factorization in perturbative QFT
Over recent years, the Lie and Hopf algebra structures of Feynman graphs have been firmly established in collaboration with Alain Connes and David Broadhurst [1–11]. Hopefully, they find their way now into the algorithmic toolkit of the practitioner of QFT. They directly address the computational practice of momentum space Feynman integrals, but can be equivalently formulated in coordinate spac...
متن کاملBalanced homodyne detectors in QFT
Within the dipole approximation we describe the interaction of a photodiode with the quantum electric field. The diode is modelled by an electron in a bound state which upon interaction, treated perturbatively in the paper, can get excited to one of the scattering states. We furthermore analyze a balanced homodyne detector (BHD) with a local oscillator (LO) consisting of two photodiodes illumin...
