Gause Symmetry and Howe Duality in 4D Conformal Field Theory Models [PDF]
Acta Polytechnica, 2010 It is known that there are no local scalar Lie fields in more than two dimensions. Bilocal fields, however, which naturally arise in conformal operator product expansions, do generate infinite Lie algebras. It is demonstrated that these Lie algebras of local observables admit (highly reducible) unitary positive energy representations in a Fock space ...

YANGIANS IN INTEGRABLE FIELD THEORIES, SPIN CHAINS AND GAUGE-STRING DUALITIES [PDF]
Reviews in Mathematical Physics, 2012 In the following paper, which is based on the author's PhD thesis submitted to Imperial College London, we explore the applicability of Yangian symmetry to various integrable models, in particular, in relation with S-matrices. One of the main themes in this work is that, after a careful study of the mathematics of the symmetry algebras one finds that ...

A tale of exceptional 3d dualities
Journal of High Energy Physics, 2019 We consider interesting Seiberg dualities for Usp gauge theories with an antisymmetric, 8 fundamentals and no superpotential. We reduce to three dimensions and systematically analyze deformations triggered by real and complex masses, reaching a plethora ...

“Chiral” and “non-chiral” 3d Seiberg duality
Journal of High Energy Physics, 2020 We propose a Seiberg duality for a 3d N $$ \mathcal{N} $$ = 2 Spin (7) gauge theory with F spinor matters. For F ≥ 6, the theory allows a magnetic dual description with an SU(F −4) gauge group.

N $$ \mathcal{N} $$ = 1 QED in 2 + 1 dimensions: dualities and enhanced symmetries
Journal of High Energy Physics, 2021 We consider three-dimensional sQED with 2 flavors and minimal supersymmetry. We discuss various models which are dual to Gross-Neveu-Yukawa theories. The U(2) ultraviolet global symmetry is often enhanced in the infrared, for instance to O(4) or SU(3 ...

Remarks on quiver gauge theories from open topological string theory [PDF]
, 2010 We study effective quiver gauge theories arising from a stack of D3-branes on certain Calabi-Yau singularities. Our point of view is a first principle approach via open topological string theory.

Bootstrapping BPS spectra of 5d/6d field theories
Journal of High Energy Physics, 2021 We propose a systematic approach to computing the BPS spectrum of any 5d/6d supersymmetric quantum field theory in Coulomb phases, which admits either gauge theory descriptions or geometric descriptions, based on the Nakajima-Yoshioka’s blowup equations.

String/Gauge Duality and Penrose Limit [PDF]
, 2003 Berenstein, Maldacena, and Nastase have recently discovered a particular limit of AdS/CFT correspondence where string theory in a plane wave background is dual to a sector of $mathcal N =4 SYM in a double scaling limit.

Scattering Amplitudes of Massive N=2 Gauge Theories in Three Dimensions [PDF]
, 2013 We study the scattering amplitudes of mass-deformed Chern-Simons theories and Yang-Mills-Chern-Simons theories with N=2 supersymmetry in three dimensions. In particular, we derive the on-shell supersymmetry algebras which underlie the scattering matrices

Dualities of corner configurations and supersymmetric indices
Journal of High Energy Physics, 2019 We compute supersymmetric indices which count local operators at certain half-BPS interfaces and quarter-BPS junctions of interfaces in four-dimensional N $$ \mathcal{N} $$ = 4 Super Yang-Mills theory.
