Lower Bound on the Energy Density in Classical and Quantum Field Theories

open access: yes, 2017
A novel method for deriving energy conditions in stable field theories is described. In a local classical theory with one spatial dimension, a local energy condition always exists.

Compactifying 5d superconformal field theories to 3d

open access: yesJournal of High Energy Physics, 2021
Building on recent progress in the study of compactifications of 6d (1, 0) superconformal field theories (SCFTs) on Riemann surfaces to 4d N $$ \mathcal{N} $$ = 1 theories, we initiate a systematic study of compactifications of 5d N $$ \mathcal{N} $$ = 1

Brane probes and gauge theory/gravity dualities [PDF]

open access: yes, 2002
We examine the use of branes as probes of supergravity geometries which arise in the study of gauge theory/gravity dualities. We investigate the moduh spaces of supersymmetric gauge theories through moduh spaces of brane probes in the dual gravity ...

Modular energy inequalities from relative entropy

open access: yesJournal of High Energy Physics, 2018
We obtain new constraints for the modular energy of general states by using the monotonicity property of relative entropy. In some cases, modular energy can be related to the energy density of states and these constraints lead to interesting relations ...

Solitons in low-dimensional sigma models [PDF]

open access: yes, 1997
The aim of this thesis is to study topological soliton solutions in classical field theories, called sigma models, on a three-dimensional space. In chapter 1 we review the general field-theoretical framework of classical soliton solutions and exemplify ...

Effective field theories of gravity: a top-down approach [PDF]

open access: yes, 2020
From water boiling to the behaviour of magnets, the world around us is often described using the language of Effective Field Theory. This powerful framework is often employed to model a system in terms of its low energy degrees of freedom without much ...

On twistors and conformal field theories from six dimensions

open access: yes, 2013
We discuss chiral zero-rest-mass field equations on six-dimensional space-time from a twistorial point of view. Specifically, we present a detailed cohomological analysis, develop both Penrose and Penrose-Ward transforms, and analyse the corresponding ...

A New Method to Explore Conformal Field Theories in Any Dimension [PDF]

open access: yes, 2011
The thesis represents an investigation into Conformal Field Theories (CFT's) in arbitrary dimensions. We propose an innovative method to extract informations about CFT's in a quantitative way.

An inverse mass expansion for the mutual information in free scalar QFT at finite temperature

open access: yesJournal of High Energy Physics, 2020
We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value ...
