Notes on cluster algebras and some all-loop Feynman integrals
Journal of High Energy Physics, 2021 We study cluster algebras for some all-loop Feynman integrals, including box-ladder, penta-box-ladder, and double-penta-ladder integrals. In addition to the well-known box ladder whose symbol alphabet is D 2 ≃ A 1 2 $$ {D}_2\simeq {A}_1^2 $$ , we show ...

Unitarity Entropy Bound: Solitons and Instantons
Fortschritte 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

Generalized symmetries and Noether’s theorem in QFT
Journal of High Energy Physics, 2022 We show that generalized symmetries cannot be charged under a continuous global symmetry having a Noether current. Further, only non-compact generalized symmetries can be charged under a continuous global symmetry.

An Effective Model for Glueballs and Dual Superconductivity at Finite Temperature
Advances 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
Advances 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.

Surface operators in superspace
Journal of High Energy Physics, 2020 We generalize the geometrical formulation of Wilson loops recently introduced in [1] to the description of Wilson Surfaces. For N = (2, 0) theory in six dimensions, we provide an explicit derivation of BPS Wilson Surfaces with non-trivial coupling to ...

Wilson loops in large symmetric representations through a double-scaling limit
Journal of High Energy Physics, 2022 We derive exact formulas for circular Wilson loops in the N $$ \mathcal{N} $$ = 4 and N $$ \mathcal{N} $$ = 2* theories with gauge groups U(N) and SU(N) in the k-fold symmetrized product representation.

Exploring non-invertible symmetries in free theories
Journal of High Energy Physics, 2023 Symmetries corresponding to local transformations of the fundamental fields that leave the action invariant give rise to (invertible) topological defects, which obey group-like fusion rules.

On the infrared divergence and global colour in N $$ \mathcal{N} $$ = 4 Yang-Mills theory
Journal of High Energy Physics, 2020 The N $$ \mathcal{N} $$ = 4 superconformal Yang-Mills theory on flat four-dimensional Minkowski space is a de-confined gauge theory in the sense that the string tension for fundamental representation coloured quarks vanishes.

Symmetry properties of Wilson loops with a Lagrangian insertion
Journal of High Energy Physics, 2022 Null Wilson loops in N $$ \mathcal{N} $$ = 4 super Yang-Mills are dual to planar scattering amplitudes. This duality implies hidden symmetries for both objects.
