Backreaction of Schwinger pair creation in massive QED
Gregory Gold, David A. McGady, Subodh P. Patil +1
Particle-antiparticle pairs can be produced by background electric fields via the Schwinger mechanism provided they are unconfined. If, as in QED in (3+1)- these particles are m…
Black hole evaporation and semiclassicality at large D
Frederik Holdt-Sørensen, David A. McGady, Nico Wintergerst
Black holes of sufficiently large initial radius are expected to be well described by a semiclassical analysis at least until half of their initial mass has evaporated away. For a…
Temperature-reflection II: Modular Invariance and T-reflection
David A. McGady
In this paper, we present robust evidence that general finite temperature quantum field theory (QFT) path integrals are invariant under reflecting temperatures to negative values (…
L-functions for Meromorphic Modular Forms and Sum Rules in Conformal Field Theory
David A. McGady
We define L-functions for meromorphic modular forms that are regular at cusps, and use them to: (i) find new relationships between Hurwitz class numbers and traces of singular modu…
Temperature-reflection I: field theory, ensembles, and interactions
David A. McGady
In this paper, we revisit the claim that many partition functions are invariant under reflecting temperatures to negative values (T-reflection). The goal of this paper is to demarc…
Short-distance Schwinger-mechanism and chiral symmetry
David A. McGady, Jon Brogård
In this paper, we study Schwinger pair production of charged massless particles in constant electric fields of finite-extent. Exploiting a map from the Dirac and Klein-Gordon equat…
Spectral sum rules for confining large-N theories
Aleksey Cherman, David A. McGady, Masahito Yamazaki
We consider asymptotically-free four-dimensional large- gauge theories with massive fermionic and bosonic adjoint matter fields, compactified on squashed three-spheres, and exam…
Modularity and 4D-2D spectral equivalences for large-N gauge theories with adjoint matter
Gökçe Başar, Aleksey Cherman, Keith R. Dienes +1
In recent work, we demonstrated that the confined-phase spectrum of non-supersymmetric pure Yang-Mills theory coincides with the spectrum of the chiral sector of a two-dimensional…
A 4D-2D equivalence for large-N Yang-Mills theory
Gokce Basar, Aleksey Cherman, Keith R. Dienes +1
General string-theoretic considerations suggest that four-dimensional large-N gauge theories should have dual descriptions in terms of two-dimensional conformal field theories. How…
Bose-Fermi Degeneracies in Large Adjoint QCD
Gokce Basar, Aleksey Cherman, David A. McGady
We analyze the large limit of adjoint QCD, an gauge theory with flavors of massless adjoint Majorana fermions, compactified on . We focus on the w…
Gravitons, Bose-symmetry, and Bonus-scaling
David A. McGady, Laurentiu Rodina
Modern on-shell S-matrix methods may dramatically improve our understanding of perturbative quantum gravity, but current foundations of on-shell techniques for General Relativity s…
Casimir energy of confining large gauge theories
Gokce Basar, Aleksey Cherman, David A. McGady +1
Four-dimensional asymptotically-free large gauge theories compactified on have a weakly-coupled confining regime when is small compared to the str…
T-Reflection
Gokce Basar, Aleksey Cherman, David A. McGady +1
We point out the presence of a temperature-reflection (-reflection) symmetry for the partition functions of many physical systems. Without knowledge of the origin of…
Anomalies without an action
Wei-Ming Chen, Yu-tin Huang, David A. McGady
Modern on-shell methods allow us to construct both the classical and quantum S-matrix for a large class of theories, without utilizing knowledge of the interacting Lagrangian. It w…
Higher-spin massless S-matrices in four-dimensions
David A. McGady, Laurentiu Rodina
On-shell, analytic S-matrix elements in massless theories are constructed from a finite set of primitive three-point amplitudes, which are fixed by Poincare invariance up to an ove…
Consistency conditions from generalized-unitarity
Yu-tin Huang, David McGady
In the modern on-shell approach, the perturbative S-matrix is constructed iteratively using on-shell building blocks with manifest unitarity. As only gauge invariant quantities ent…
One-loop renormalization and the S-matrix
Yu-tin Huang, David A. McGady, Cheng Peng
In four-dimensional theories with massless particles, the one-loop amplitudes can be expressed in terms of a basis of scalar integrals and rational terms. Since the scalar bubble i…
