A Toy Model of the Information Paradox in Empty Space by Suvrat Raju

“…We construct an analogous paradox in empty anti-de Sitter space. In a local quantum field theory, Bell correlations between operators localized in mutually spacelike regions are monogamous. …”

Searching for Quantum Black Hole Structure with the Event Horizon Telescope by Steven B. Giddings

“…Two related scenarios for reconciling quantum mechanics with the existence of black hole-like objects, with “minimal” departure from general relativity and local quantum field theory, have been explored; one of these could produce signatures visible to EHT observations. …”

Consistency of Higgsplosion in localizable QFT by Valentin V. Khoze, Michael Spannowsky

“…The corresponding localizable fields need not be tempered distributions, and they fit well into the framework of local quantum field theory. Keywords: Higgs particle, Multi-particle production, Higgsplosion, Semiclassical methods…”

Continuous entanglement renormalization on the circle by Ling-Yan Hung, Guifré Vidal

“…In addition, in the case of a Gaussian cMERA for noninteracting quantum fields, the method of images allows us to prove the following result: If on the line a cMERA state is a good approximation to a ground state of a local quantum field theory (QFT) Hamiltonian, then (under mild assumptions on their correlation functions) the resulting cMERA on a circle is also a good approximation to the ground state of the same local QFT Hamiltonian on the circle.…”

Holographic complexity of LST and single trace T T ¯ $$ T\overline{T} $$ by Soumangsu Chakraborty, Gaurav Katoch, Shubho R. Roy

“…When the cutoff UV scale is much smaller than the non-locality (Hagedorn) scale, we find exotic quadratic and logarithmic divergences (for both volume and action complexity) which are not expected in a local quantum field theory. We also generalize our computation to include the effects of finite temperature. …”

Status and prospects for CPT and Lorentz invariance violation searches in neutral meson mixing by Jeroen van Tilburg, Maarten van Veghel

“…Since CPT violation implies violation of Lorentz invariance in an interacting local quantum field theory, the observed CPT asymmetry will exhibit sidereal- and boost-dependent variations. …”

On the questions of asymptotic recoverability of information and subsystems in quantum gravity by Steven B. Giddings

“…The gauge symmetry and necessity of solving the gravitational constraints appear to imply that the answers to this question here are different than in finite quantum systems, or in local quantum field theory. Specifically, the constraints can be solved by providing a “gravitational dressing” for the underlying field-theory operators, but this modifies their locality properties. …”

Entanglement and separability in continuum Rokhsar-Kivelson states by Christian Boudreault, Clément Berthiere, William Witczak-Krempa

“…We study a vast family of continuum Rokhsar-Kivelson (RK) states, which have their ground state encoded by a local quantum field theory. These describe certain quantum magnets, and are also important in quantum information. …”

The role of positivity and causality in interactions involving higher spin by Bert Schroer

“…It is shown that the recently introduced positivity and causality preserving string-local quantum field theory (SLFT) resolves most No-Go situations in higher spin problems. …”

Photon masses in the landscape and the swampland by Matthew Reece

“…Application of Tower or Sublattice variants of the Weak Gravity Conjecture makes this statement more precise: for a spin-1 vector boson with coupling constant e and Stückelberg mass m, local quantum field theory breaks down at energies at or below ΛUV = min((mM Pl/e)1/2, e 1/3 M Pl). …”

Chaos and entanglement spreading in a non-commutative gauge theory by Willy Fischler, Viktor Jahnke, Juan F. Pedraza

“…This implies that non-local interactions can enhance the effective light-cone for the transfer of quantum information, eluding previously conjectured bounds encountered in the context of local quantum field theory. We comment on a possible limitation on the retrieval of quantum information imposed by non-locality.…”
