Universal criticality of thermodynamic geometry for boundary conformal field theories in gauge/gravity duality [PDF]
According to more recent AdS/CFT interpretation \cite{Karch:2015rpa}, in which varying cosmological constant $ $ in the bulk corresponds to varying the curvature radius governing the space on which the field theory resides, we study the criticality of thermodynamic curvatures for thermal boundary conformal field theories (CFT) that are dual to $d ...

YANGIANS IN INTEGRABLE FIELD THEORIES, SPIN CHAINS AND GAUGE-STRING DUALITIES [PDF]
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 ...

Boundary electromagnetic duality from homological edge modes
Recent years have seen a renewed interest in using ‘edge modes’ to extend the pre-symplectic structure of gauge theory on manifolds with boundaries.

Inverse Magnetic Catalysis in Field Theory and Gauge-Gravity Duality [PDF]
We investigate the surface of the chiral phase transition in the three-dimensional parameter space of temperature, baryon chemical potential and magnetic field in two different approaches, the field-theoretical Nambu-Jona-Lasinio (NJL) model and the holographic Sakai-Sugimoto model.

Gause Symmetry and Howe Duality in 4D Conformal Field Theory Models [PDF]
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 ...

Intersecting surface defects and 3d superconformal indices
We compute the 3d N $$ \mathcal{N} $$ = 2 superconformal indices for 3d/1d coupled systems, which arise as the worldvolume theories of intersecting surface defects engineered by Higgsing 5d N $$ \mathcal{N} $$ = 1 gauge theories. We generalize some known

Duality and Integrability in Superstring and Gauge Field Theory [PDF]
In the present thesis, we explore certain aspects of superstring and supersymmetric gauge field theory, independently as well as in the context of the holographic duality.The first part of the thesis is devoted to classical integrability and, in particular, to certain methods of analytic non-integrability, which are employed on various supergravity vacua.

Nonlinear electrodynamics without birefringence
All solutions of the no-birefringence conditions for nonlinear electrodynamics are found. In addition to the known Born-Infeld and Plebanski cases, we find a “reverse Born-Infeld” case, which has a limit to Plebanski, and an “extreme-Born-Infeld” case ...
