OSCILLONS IN SCALAR FIELD THEORIES: APPLICATIONS IN HIGHER DIMENSIONS AND INFLATION [PDF]

International Journal of Modern Physics D, 2007
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 spacetime.

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 ...

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.

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 ...

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.

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.

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.

BPS skyrmions of generalized Skyrme model in higher dimensions

Journal of High Energy Physics, 2022
In this work we consider the higher dimensional Skyrme model, with spatial dimension d > 3, focusing on its BPS submodels and their corresponding features.
