Liouville conformal field theories in higher dimensions [PDF]
Journal of High Energy Physics, 2018 We consider a generalization of the two-dimensional Liouville conformal field theory to any number of even dimensions. The theories consist of a log-correlated scalar field with a background Q $$ \mathcal{Q} $$-curvature charge and an exponential ...

OSCILLONS IN SCALAR FIELD THEORIES: APPLICATIONS IN HIGHER DIMENSIONS AND INFLATION [PDF]
International Journal of Modern Physics D, 2006 The basic properties of oscillons — localized, long-lived, time-dependent scalar field configurations — are briefly reviewed, including recent results demonstrating how their existence depends on the dimensionality of space–time.

Symmetry resolved entanglement of excited states in quantum field theory. Part II. Numerics, interacting theories and higher dimensions [PDF]
Journal of High Energy Physics, 2022 In a recent paper we studied the entanglement content of zero-density excited states in complex free quantum field theories, focusing on the symmetry resolved entanglement entropy (SREE).

Constraining conformal field theories with a higher spin symmetry in d > 3 dimensions [PDF]
Journal of High Energy Physics, 2016 We study unitary conformal field theories with a unique stress tensor and at least one higher-spin conserved current in d > 3 dimensions. We prove that every such theory contains an infinite number of higher-spin conserved currents of arbitrarily high ...

Constructing Carrollian field theories from null reduction [PDF]
Journal of High Energy Physics, 2023 In this paper, we propose a novel way to construct off-shell actions of d-dimensional Carrollian field theories by considering the null-reduction of the Bargmann invariant actions in d +1 dimensions.

Testing symmetries in effective models of higher derivative field theories [PDF]
, 2009 Higher derivative field theories with interactions raise serious doubts about their validity due to severe energy instabilities. In many cases the implementation of a direct perturbation treatment to excise the dangerous negative-energies from a higher ...

A roadmap for bootstrapping critical gauge theories: decoupling operators of conformal field theories in $d>2$ dimensions [PDF]
SciPost Physics, 2021 We propose a roadmap for bootstrapping conformal field theories (CFTs) described by gauge theories in dimensions d>2d>2. In particular, we provide a simple and workable answer to the question of how to detect the gauge group in the bootstrap calculation.

Casimir energy and modularity in higher-dimensional conformal field theories [PDF]
Journal of High Energy Physics, 2022 An important problem in Quantum Field Theory (QFT) is to understand the structures of observables on spacetime manifolds of nontrivial topology. Such observables arise naturally when studying physical systems at finite temperature and/or finite volume ...

On higher-dimensional Carrollian and Galilean conformal field theories [PDF]
SciPost Physics, 2021 In this paper, we study the Carrollian and Galilean conformal field theories (CCFT and GCFT) in d>2d>2 dimensions. We construct the highest weight representations (HWR) of Carrollian and Galilean conformal algebra (CCA and GCA).

Reflected entropy and Markov gap in Lifshitz theories
Journal of High Energy Physics, 2023 We study the reflected entropy in (1+1)-dimensional Lifshitz field theory whose groundstate is described by a quantum mechanical model. Starting from tripartite Lifshitz groundstates, both critical and gapped, we derive explicit formulas for the Rényi ...
