三亚国际数学论坛：Superconformal Field Theories in 6 and Lower Dimensions
三亚国际数学论坛 Superconformal Field Theories in 6 Lower Dimensions
2017/11/24
Conformal field theories represent a very active research field worldwide with many international experts working on various aspects of the topic. Progress during the past several years has led to man...
When Effective Field Theories Fail
Effective field theory the meson circulation perturbation theory reggie physics
2014/12/19
In this talk, I describe and defend four non-standard claims about four effective field theories, and try to extract some lessons about the limits of effective field theory. The four theses (and a cap...
Dimension of the moduli space and Hamiltonian analysis of BF field theories
Index theorem moduli space Hamiltonian dynamics
2011/9/22
Abstract: By using the Atiyah-Singer theorem through some similarities with the instanton and the anti-instanton moduli spaces, the dimension of the moduli space for two and four-dimensional BF theori...
Dualities in Field Theories and the Role of K-Theory
duality S-duality T-duality K-theory AdS/CFT correspondence D-brane
2011/10/9
Abstract: It is now known (or in some cases just believed) that many quantum field theories exhibit dualities, equivalences with the same or a different theory in which things appear very different, b...
Supersymmetric K field theories and defect structures
supersymmetric K field theories defect structures High Energy Physics - Theory
2011/10/9
Abstract: We construct supersymmetric K field theories (i.e., theories with a non-standard kinetic term) in 1+1 and 2+1 dimensions such that the bosonic sector just consists of a nonstandard kinetic t...
Field theories with defects and the centre functor
Field theories defects the centre functor Quantum Algebra
2011/8/24
Abstract: This note is intended as an introduction to the functorial formulation of quantum field theories with defects. After some remarks about models in general dimension, we restrict ourselves to ...

Noncommutative deformations of quantum field theories, locality, and causality
noncommutative quantum field theory Moyal and Wick-Voros star products
2011/3/3
We investigate noncommutative deformations of quantum field theories for different star products, particularly emphasizing the locality properties and the regularity of the deformed fields.
Non-existence of non-topological solitons in some types of gauge field theories in Minkowski space
Non-existence of non-topological solitons types of gauge field theories Minkowski space
2011/1/17
In this paper the conditions, under which non-topological solitons are absent in Yang-Mills theory coupled to a non-linear scalar field in Minkowski space, are obtained. It is also shown that non-topo...
Conformal field theories in anti-de Sitter space
Conformal field theories anti-de Sitter space
2010/12/24
In this paper we discuss the dynamics of conformal field theories on anti-de Sitter space, focussing on the special case of the N=4 supersymmetric Yang-Mills theory on AdS_4. We argue that the choice...
Invitation to Topological Conformal Field Theories

2010/11/18
Topological conformal field theories are defined using only basic results from the theory of quasiconformal mappings.
Two-dimensional topological field theories as taffy
Two-dimensional topological field theories taffy
2010/12/22
In this paper we use trivial defects to define global taffy-like operations on string worldsheets, which preserve the field theory. We fold open and closed strings on a space X into open strings on p...
First order parent formulation for generic gauge field theories
First order parent formulation generic gauge field theories
2010/12/15
We show how a generic gauge field theory described by a BRST differential can systematically be reformulated as a first order parent system whose spacetime part is determined by the de Rham differenti...
A Deformed Poincare Invariance for Group Field Theories
Poincare Invariance Group Field Theories
2010/3/18
In the context of quantum gravity, group field theories are field theories that generate spinfoam amplitudes as Feynman diagrams. They can be understood as generalizations of the matrix models used fo...
