Cutting multiparticle correlators down to size by Komiske, Patrick T., Metodiev, Eric Mario, Thaler, Jesse

“…Multiparticle correlators are mathematical objects frequently encountered in quantum field theory and collider physics. By translating multiparticle correlators into the language of graph theory, we can gain new insights into their structure as well as identify efficient ways to manipulate them. …”

Unifying constructions of non-invertible symmetries by Lakshya Bhardwaj, Sakura Schäfer-Nameki, Apoorv Tiwari

“…In the past year several constructions of non-invertible symmetries in Quantum Field Theory in $d≥3$ have appeared. In this paper we provide a unified perspective on these constructions. …”

Semiclassical gravity beyond coherent states by Shahnewaz Ahmed, Caroline Lima, Eduardo Martín-Martínez

“…Abstract We show that it is possible to still use semiclassical gravity together with quantum field theory beyond the regimes where the field state is coherent. …”

Dynamical response of quasi 1D Mott insulators by Essler, F, Tsvelik, A

“…At low energies certain one dimensional Mott insulators can be described in terms of an exactly solvable quantum field theory, the U(1) Thirring model. Using exact results derived from integrability we determine dynamical properties like the frequency dependent optical conductivity and the single-particle Green's function. …”

Arithmetic Chern-Simons Theory II by Chung, H, Kim, D, Kim, M, Park, J, Yoo, H

“…We apply ideas of Dijkgraaf and Witten on three-dimensional topological quantum field theory to arithmetic curves, that is, the spectra of rings of integers in algebraic number fields. …”

Localisations of cobordism categories and invertible TFTs in dimension two by Juer, R, Tillmann, U

“…Cobordism categories have played an important role in classical geometry and more recently in mathematical treatments of quantum field theory. Here we will compute localisations of two-dimensional discrete cobordism categories. …”

Cavity QED of superradiant phase transition in two dimensional materials by Li, Benliang

“…In chapter 5, we are going to derive the OPQM from the quantum field theory, i.e., the quantum electrodynamics (QED) to be specific. …”

Causal structure of the entanglement renormalization ansatz by Cédric Bény

“…This result clarifies the nature of the ansatz, and suggests a generalization to quantum field theory. It also constitutes an independent justification of the connection between MERA and hyperbolic geometry which was proposed as a concrete implementation of the AdS-CFT correspondence.…”

Bohrification of local nets by Joost Nuiten

“…We extend these ideas from quantum mechanics to algebraic quantum field theory: from a net of observables we construct a presheaf of quantum phase spaces. …”

Elastic Kink-Meson scattering by Jarah Evslin, Hui Liu

“…Abstract In classical field theory, radiation does not reflect off of reflectionless kinks. In quantum field theory, radiation quanta, called mesons, can be reflected. …”

A proposal for testing subcritical vacuum pair production with high power lasers by Gregori, G, Blaschke, D, Rajeev, P, Chen, H, Clarke, R, Huffman, T, Murphy, C, Prozorkevich, A, Roberts, C, Röpke, G, Schmidt, S, Smolyansky, SA, Wilks, S, Bingham, R

“…We present a proposal for testing the prediction of non-equilibrium quantum field theory below the Schwinger limit. The proposed experiments should be able to detect a measurable number of gamma rays resulting from the annihilation of pairs in the focal spot of two opposing high intensity laser beams. …”
