EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
Benchmarking regulator-sourced 2PI and average 1PI flow equations in zero dimensions
Peter Millington, Paul M. Saffin
We elucidate the regulator-sourced 2PI and average 1PI approaches for deriving exact flow equations in the case of a zero dimensional quantum field theory, wherein the scale depend…
Fifth-Force Screening around Extremely Compact Sources
Clare Burrage, Benjamin Elder, Peter Millington +2
Many non-linear scalar field theories possess a screening mechanism that can suppress any associated fifth force in dense environments. As a result, these theories can evade local…
Statistics on Lefschetz thimbles: Bell/Leggett-Garg inequalities and the classical-statistical approximation
Peter Millington, Zong-Gang Mou, Paul M. Saffin +1
Inspired by Lefschetz thimble theory, we treat Quantum Field Theory as a statistical theory with a complex Probability Distribution Function (PDF). Such complex-valued PDFs permit…
Discrete spacetime symmetries and particle mixing in non-Hermitian scalar quantum field theories
Jean Alexandre, John Ellis, Peter Millington
We discuss second quantization, discrete symmetry transformations and inner products in free non-Hermitian scalar quantum field theories with PT symmetry, focusing on a prototype m…
PT-Symmetric Non-Hermitian Quantum Field Theories with Supersymmetry
Jean Alexandre, John Ellis, Peter Millington
We formulate supersymmetric non-Hermitian quantum field theories with PT symmetry, starting with free chiral boson/fermion models and then including trilinear superpotential intera…
