Local duality symmetry in gauge field theories [PDF]

open access: green, 2020
We develop the idea of local duality symmetry (LDS) in gauge field theories. Using Clifford algebra techniques we construct dually invariant scalar Lagrangian of electrodynamics in the presence of sources and demonstrate that in tensor formalism it is exactly the same as the usual one. Then we localize the duality symmetry with two possible options for

Inverse Magnetic Catalysis in Field Theory and Gauge-Gravity Duality [PDF]

open access: green, 2013
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.

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

open access: greenReviews 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 ...

Perturbative Methods for Superconformal Quantum Field Theories in String - Gauge Theory Dualities [PDF]

open access: green, 2012
This review covers a number of applications of conformal field theory methods for perturbative calculations in N=4 Super Yang-Mills and ABJM theory. After motivating the role of superconformal symmetry for elementary particle physics research, we review some basic facts about conformal symmetry and conformal transformations of fields in a pedagogical ...

Aspects of strongly-coupled field theory from gauge-gravity duality [PDF]

open access: green, 2009
The issue of calculating at strong coupling is a hard problem in physics. The discovery of gauge-gravity duality at the end of the Twentieth Century provides a novel means of calculating in a large-N gauge theory at strong coupling. In this thesis we apply the method of gauge-gravity duality to a variety of questions.
