Unitarity Entropy Bound: Solitons and Instantons

open access: yesFortschritte der Physik, Volume 69, Issue 1, January 2021., 2021
Abstract We show that non‐perturbative entities such as solitons and instantons saturate bounds on entropy when the theory saturates unitarity. Simultaneously, the entropy becomes equal to the area of the soliton/instanton. This is strikingly similar to black hole entropy despite absence of gravity. We explain why this similarity is not an accident. We

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
The glueballs lead to gluon and QCD monopole condensations as by‐products of color confinement. A color dielectric function G(∣ϕ∣) coupled with a Abelian gauge field is properly defined to mediate the glueball interactions at confining regime after spontaneous symmetry breaking (SSB) of the gauge symmetry. The particles are expected to form through the

Holographic Description of Noncommutative Schwinger Effect

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
We consider the phenomenon of spontaneous pair production in the presence of an external electric field for noncommutative Yang‐Mills theories. Using Maldacena’s holographic conjecture, the threshold electric field for pair production is computed from the quark/antiquark potential for noncommutative theories.

Chaos and the reparametrization mode on the AdS2 string

open access: yesJournal of High Energy Physics, 2023
We study the holographic correlators corresponding to scattering of fluctuations of an open string worldsheet with AdS2 geometry. In the out-of-time-order configuration, the correlators display a Lyapunov growth that saturates the chaos bound.

Wilson loops in circular quiver SCFTs at strong coupling

open access: yesJournal of High Energy Physics, 2021
We study circular BPS Wilson loops in the N $$ \mathcal{N} $$ = 2 superconformal n-node quiver theories at large N and strong ’t Hooft coupling by using localization.

Conformal constraints on defects

open access: yesJournal of High Energy Physics, 2020
In this paper we study the constraints imposed by conformal invariance on extended objects a.k.a. defects in a conformal field theory. We identify a particularly nice class of defects that is closed under conformal transformations.

Minimal area surfaces in AdS n+1 and Wilson loops

open access: yesJournal of High Energy Physics, 2018
The AdS/CFT correspondence relates the expectation value of Wilson loops in N $$ \mathcal{N} $$ = 4 SYM to the area of minimal surfaces in AdS 5. In this paper we consider minimal area surfaces in generic Euclidean AdS n+1 using the Pohlmeyer reduction ...

Loop operators in three-dimensional N $$ \mathcal{N} $$ = 2 fishnet theories

open access: yesJournal of High Energy Physics, 2020
In this work, we study the line and loop operators in three-dimensional N $$ \mathcal{N} $$ = 2 fishnet theories in detail. We construct the straight line and circular loop operators which are at least classically half-BPS.

Integrated correlators with a Wilson line in N $$ \mathcal{N} $$ = 4 SYM

open access: yesJournal of High Energy Physics, 2023
In the context of integrated correlators in N $$ \mathcal{N} $$ = 4 SYM, we study the 2-point functions of local operators with a superconformal line defect. Starting from the mass-deformed N $$ \mathcal{N} $$ = 2* theory in presence of a 1 2 $$ \frac{1}{

Toward precision holography in type IIA with Wilson loops

open access: yesJournal of High Energy Physics, 2018
We study the one-loop effective action of certain classical type IIA string configurations in AdS4 × ℂℙ3. These configurations are dual to Wilson loops in the N=6 $$ \mathcal{N}=6 $$ U(N) k × U(N)−k Chern-Simons theory coupled to matter whose expectation
