Constraints on the spectrum of field theories with non-integer symmetry from quantum evanescence
Weiguang Cao, Xiaochuan Lu, Tom Melia
We identify constraints in the energy spectra of quantum theories that have a global symmetry, where is treated as a continuous parameter. We point out that a class of e…
The Classical Equations of Motion of Quantized Gauge Theories, Part 2: Electromagnetism
David E. Kaplan, Tom Melia, Surjeet Rajendran
In this and companion papers, we show that quantum field theories with gauge symmetries permit a broader class of classical dynamics than typically assumed. In this article, we sho…
The Classical Equations of Motion of Quantized Gauge Theories, Part I: General Relativity
David E. Kaplan, Tom Melia, Surjeet Rajendran
In this and a companion paper, we show that quantum field theories with gauge symmetries permit a broader class of classical dynamics than typically assumed. In this article, we sh…
Outer Automorphism Anomalies
Brian Henning, Xiaochuan Lu, Tom Melia +1
We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for and parities for . We emphasize…
Universal fine grained asymptotics of free and weakly coupled Quantum Field Theory
Weiguang Cao, Tom Melia, Sridip Pal
We give a rigorous proof that in any free quantum field theory with a finite group global symmetry , on a compact spatial manifold, at sufficiently high energy, the den…
EFT Asymptotics: the Growth of Operator Degeneracy
Tom Melia, Sridip Pal
We establish formulae for the asymptotic growth (with respect to the scaling dimension) of the number of operators in effective field theory, or equivalently the number of -matr…
