Perturbative symplectic field theory and Wigner function
(Elsevier, 2009-09-15)
We study relativistic quantum field theories in phase space, based on representations of the Poincaré group, using the Moyal product. We develop a perturbative theory for quantizing fields, with functional methods in phase ...
Comments on correlation functions of large spin operators and null polygonal Wilson loops
(Elsevier B.V., 2013-02-11)
We discuss the relation between correlation functions of twist-two large spin operators and expectation values of Wilson loops along light-like trajectories. After presenting some heuristic field theoretical arguments ...
Defects in conformal field theory
(2016-04-01)
Abstract: We discuss consequences of the breaking of conformal symmetry by a flat or spherical extended operator. We adapt the embedding formalism to the study of correlation functions of symmetric traceless tensors in the ...
Sistemas com dois geradores supersimétricos
(Universidade Estadual Paulista (Unesp), 2010-04-04)
Neste estudo iremos aplicar supersimetria em teorias como mecânica quântica, teoria de cordas e teoria de campos em D = 3. Apesar de todas essas teorias terem aplicações em campos completamente diferentes iremos encontrar ...
