On the Status of Wormholes in Einstein’s Theory: An Overview by Peter K.F. Kuhfittig

“… It has been claimed that wormholes are just as good a prediction of Einstein’s theory as black holes, but they are subject to severe restrictions from quantum field theory. The purpose of this paper is to show that the claim can be substantiated in spite of these restrictions. …”

PARTICLE CREATION BY GRAVITATIONAL-FIELDS by Woodhouse, N

“…This paper presents a new and generally covariant approach to quantum field theory in curved space-time. Previously unknown expressions are obtained for particle creation amplitudes in oscillating gravitational fields. …”

A primer in Tensor Analysis and Relativity / by Shapiro, I. L. (Ilya Lvovitch), author 636149

“…Part III contains an extended discussion of general relativity, and includes material useful for students interested primarily in quantum field theory and quantum gravity. Tailored to the undergraduate, this textbook offers explanations of technical material not easily found or detailed elsewhere, including an understandable description of Riemann normal coordinates and conformal transformations. …”

Resonance-based schemes for dispersive equations via decorated trees by Yvain Bruned, Katharina Schratz

“…The field of singular SPDEs took advantage of numerical methods and renormalisation in perturbative quantum field theory by extending their structures via the adjunction of decorations and Taylor expansions. …”

Moments for positivity: using Drell-Yan data to test positivity bounds and reverse-engineer new physics by Xu Li, Ken Mimasu, Kimiko Yamashita, Chengjie Yang, Cen Zhang, Shuang-Yong Zhou

“…The same operators are also subject to positivity bounds, when requiring the associated (unknown) UV completion to obey basic principles of quantum field theory. We perform a phenomenological study to quantify the sensitivity of the high-luminosity LHC to this set of operators and, by extension, the positivity bounds. …”

Universal non-invertible symmetries by Bhardwaj, L, Schäfer-Nameki, S, Wu, J

“…<p>It is well-known that gauging a finite 0-form symmetry in a quantum field theory leads to a dual symmetry generated by topological Wilson line defects. …”

Considerations Concerning the Little Group by Jens Erler

“…I very briefly review both the historical and constructive approaches to relativistic quantum mechanics and relativistic quantum field theory, including remarks on the possibility of a non-vanishing photon mass, as well as a foolhardy speculation regarding dark matter.…”

Graphical functions in parametric space by Golz, M, Panzer, E, Schnetz, O

“…Graphical functions are positive functions on the punctured complex plane $\mathbb{C}\setminus\{0,1\}$ which arise in quantum field theory. We generalize a parametric integral representation for graphical functions due to Lam, Lebrun and Nakanishi, which implies the real analyticity of graphical functions. …”

Mission Target: Exotic Multiquark Hadrons—Sharpened Blades by Wolfgang Lucha

“…Motivated by recent experimental progress in establishing the likely existence of (variants of) exotic hadrons, predicted to be formed by the strong interactions, various proposed concepts and ideas are compiled in an attempt to draft a coherent picture of the achievable improvement in the theoretical interpretation of exotic hadrons in terms of the underlying quantum field theory of strong interactions.…”

Comments on summing over bordisms in TQFT by Anindya Banerjee, Gregory W. Moore

“…Abstract Recent works in quantum gravity, motivated by the “factorization problem” and “baby universes,” have considered sums over bordisms with fixed boundaries in topological quantum field theory (TQFT). We discuss this construction and observe a curious splitting formula for the total amplitude.…”
