Group field theories for all loop quantum gravity [PDF]
New Journal of Physics, 2014 Group field theories represent a second quantized reformulation of the loop quantum gravity state space and a completion of the spin foam formalism. States of the canonical theory, in the traditional continuum setting, have support on graphs of arbitrary

Deformations of Quantum Field Theories and Integrable Models [PDF]
Communications in Mathematical Physics, 2011 Deformations of quantum field theories which preserve Poincaré covariance and localization in wedges are a novel tool in the analysis and construction of model theories. Here a general scenario for such deformations is discussed, and an infinite class of

Aspects of pseudoentropy in field theories [PDF]
Physical Review Research, 2021 In this article, we explore properties of pseudo entropy [1] in quantum field theories and spin systems from several approaches. Pseudo entropy is a generalization of entanglement entropy such that it depends on both an initial and final state and has a ...

Particle detectors from localized quantum field theories [PDF]
Physical Review D, 2023 We present a fully relativistic model for localized probes in quantum field theory. Furthermore, we show that it is possible to obtain particle detector models from localized quantum field theories that interact with a free quantum field.

Simulating Collider Physics on Quantum Computers Using Effective Field Theories. [PDF]
Physical Review Letters, 2021 Simulating the full dynamics of a quantum field theory over a wide range of energies requires exceptionally large quantum computing resources. Yet for many observables in particle physics, perturbative techniques are sufficient to accurately model all ...

Achieving the quantum field theory limit in far-from-equilibrium quantum link models [PDF]
Quantum, 2022 Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along with potential applications in quantum information and science ...

Simulating two-dimensional lattice gauge theories on a qudit quantum computer [PDF]
Nature Physics, 2023 Particle physics describes the interplay of matter and forces through gauge theories. Yet, the intrinsic quantum nature of gauge theories makes important problems notoriously difficult for classical computational techniques.

Any consistent coupling between classical gravity and quantum matter is fundamentally irreversible [PDF]
Quantum, 2023 When gravity is sourced by a quantum system, there is tension between its role as the mediator of a fundamental interaction, which is expected to acquire nonclassical features, and its role in determining the properties of spacetime, which is inherently ...

A study of quantum field theories in AdS at finite coupling [PDF]
Journal of High Energy Physics, 2018 A bstractWe study the O(N) and Gross-Neveu models at large N on AdSd+1 background. Thanks to the isometries of AdS, the observables in these theories are constrained by the SO(d, 2) conformal group even in the presence of mass deformations, as was ...
