Duality, Superconvergence and the Phases of Gauge Theories [PDF]

open access: yes, 1997
Results about the phase structure of certain N=1 supersymmetric gauge theories, which have been obtained as a consequence of holomorphy and `electric-magnetic' duality, are shown to be in quantitative agreement with corresponding consequences of ...

Deformations of duality-symmetric theories [PDF]

open access: yes, 2001
We prove that a sum of free non-covariant duality-symmetric actions does not allow consistent, continuous and local self-interactions that deform the gauge transformations.

Duality of Non-Supersymmetric Large N Gauge Theories [PDF]

open access: yes, 1998
Starting from Seiberg's electric-magnetic duality for supersymmetric QCD, we construct dual pairs of non-supersymmetric gauge theories. This is accomplished by first taking the large N limit of supersymmetric QCD and its dual partner and then performing ...

Topological dualities in the Ising model

open access: yes, 2021
We relate two classical dualities in low-dimensional quantum field theory: Kramers-Wannier duality of the Ising and related lattice models in $2$ dimensions, with electromagnetic duality for finite gauge theories in $3$ dimensions.

Holographic models of de Sitter QFTs [PDF]

open access: yes, 2010
We describe the dynamics of strongly coupled field theories in de Sitter spacetime using the holographic gauge/gravity duality. The main motivation for this is to explore the possibility of dynamical phase transitions during cosmological evolution ...

Noncommutative Sp(2,R) Gauge Theories - A Field Theory Approach to Two-Time Physics [PDF]

open access: yes, 2001
Phase-space and its relativistic extension is a natural space for realizing Sp(2,R) symmetry through canonical transformations. On a Dx2 dimensional covariant phase-space, we formulate noncommutative field theories, where Sp(2,R) plays a role as either a

Dualities in 4D Theories with Product Gauge Groups from Brane Configurations [PDF]

open access: yes, 1997
We study brane configurations which correspond to N=1 field theories in four dimensions. By inverting the order of the NS 5-branes and D6-branes, a check on dualities in four dimensional theories can be made.

The Structure of Multiloop Amplitudes in Gauge and Gravity Theories

open access: yes, 2010
We review the recently discovered duality between color and kinematics in gauge theories. This duality leads to a remarkably simple double-copy relation between diagrammatic numerators of gravity scattering amplitudes and gauge-theory ones.

Two Dimensional Mirror Symmetry From M-theory [PDF]

open access: yes, 1997
We construct two dimensional gauge theories with $N= (4,4)$ supersymmetry from branes of type IIA string theory. Quantum effects in the two dimensional gauge theory are analyzed by embedding the IIA brane construction into M-theory.

Duality and Superconvergence Relation in Supersymmetric Gauge Theories

open access: yes, 1997
We investigate the phase structures of various N=1 supersymmetric gauge theories including even the exceptional gauge group from the viewpoint of superconvergence of the gauge field propagator.
