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 ...

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 spin, and that Ward identities generated by the conserved charges of these currents imply that the ...

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 ...

Effective Lagrangian and stability analysis in warped space
Journal of High Energy Physics, 2022 In the warped space model, the inter-brane distance can be stabilized by the Goldberger-Wise mechanism. Of particular importance, the stabilization potential calls for a proper identification of the dynamical degree of freedom. In this paper, we provided

Kink scattering in the presence of geometric constrictions
Journal of High Energy Physics, 2023 We investigate kink-antikink collisions in a model characterized by two scalar fields in the presence of geometric constrictions. The model includes an auxiliary function that modifies the kinematics associated with one of the two fields.

Light-ray moments as endpoint contributions to modular Hamiltonians
Journal of High Energy Physics, 2021 We consider excited states in a CFT, obtained by applying a weak unitary perturbation to the vacuum. The perturbation is generated by the integral of a local operator J (n) of modular weight n over a spacelike surface passing through x = 0.

Quantum quench and thermalization to GGE in arbitrary dimensions and the odd-even effect
Journal of High Energy Physics, 2020 In many quantum quench experiments involving cold atom systems the post-quench phase can be described by a quantum field theory of free scalars or fermions, typically in a box or in an external potential.

Conformal bootstrap deformations
Journal of High Energy Physics, 2022 We explore the space of extremal functionals in the conformal bootstrap. By recasting the bootstrap problem as a set of non-linear equations parameterized by the CFT data, we find an efficient algorithm for converging to the extremal solution ...

Capacity of entanglement in local operators
Journal of High Energy Physics, 2021 We study the time evolution of the excess value of capacity of entanglement between a locally excited state and ground state in free, massless fermionic theory and free Yang-Mills theory in four spacetime dimensions.
