One-loop CHY-integrand of bi-adjoint scalar theory

open access: yesJournal of High Energy Physics, 2020
In this paper, the one-loop CHY-integrands of bi-adjoint scalar theory has been reinvestigated. Differing from previous constructions, we have explicitly removed contributions from tadpole and massless bubbles when taking the forward limit of ...

From locality to irregularity: introducing local quenches in massive scalar field theory

open access: yesJournal of High Energy Physics, 2023
In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension and generalize the well-known two ...

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 ...

Localization and Dualities in Three Dimensional Superconformal Field Theories [PDF]

open access: yes, 2012
In this thesis we apply the technique of localization to three-dimensional N=2 superconformal field theories. We consider both theories which are exactly superconformal, and those which are believed to flow to nontrivial superconformal fixed points, for

Quantum aspects of classically conformal theories in four and six dimensions [PDF]

open access: yes, 2021
Die perturbative Quantenfeldtheorie ist das am weitesten entwickelte Modell, zur präzisen Analyse vieler verschiedener physikalischer Phänomene. Das Standardwerkzeug der perturbativen QFT sind Feynman-Diagramme.

Quantum revivals in conformal field theories in higher dimensions [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2016
We investigate the behavior of the return amplitude ${\cal F}(t)= |\langleΨ(0)|Ψ(t)\rangle|$ following a quantum quench in a conformal field theory (CFT) on a compact spatial manifold of dimension $d-1$ and linear size $O(L)$, from a state $|Ψ(0)\rangle$ of extensive energy with short-range correlations.

Localization of Gauge Theories on the Three-Sphere [PDF]

open access: yes, 2012
We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

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

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

open access: yesInternational 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 space–time. Their role on the dynamics of phase transitions is discussed, and it is shown that oscillons may greatly accelerate the ...
