The Positivity Geometry of Photon--Dark-Photon Effective Field Theories
Sayantan Chakraborty, Yash Dadhwal, Arun M. Thalapillil
We derive positivity bounds on the complete dimension-eight effective field theory of photons and a massless dark photon. The mixed gauge sector contains twelve CP-even Wilson coef…
New quantum information perspectives in the axion--photon and neutrino systems
Aaditya Datar, Arun M. Thalapillil, Palak Thareja
In this work, we broach a quantum information-theoretic treatment of axion--photon mixing. Motivated by an emerging class of quantum-enhanced axion searches, we analyse the two-lev…
Resurgence in the two-field scalar and spinor Quantum Electrodynamics Euler-Heisenberg Lagrangian
Drishti Gupta, Arun Thalapillil
We present the first systematic resurgent analysis of the Euler-Heisenberg Lagrangian in spinor and scalar quantum electrodynamics for the most general constant background field co…
