Fundamentos da dualidade AdS/CFT
(2019-08-15)
Uma revisão detalhada do espaço-tempo Anti-de Sitter (AdS) é realizada. A Teoria Conforme
de Campos (CFT) é destrinchada. O princípio holográfico enquanto consequência
da termodinâmica dos buracos negros é apresentado e ...
The structure of non-abelian kinks
(Springer, 2013-10-10)
We consider a class of integrable quantum field theories in 1 + 1 dimensions whose classical equations have kink solutions with internal collective coordinates that transform under a non-abelian symmetry group. These ...
Observables in the Guarino-Jafferis-Varela/CS-SYM duality
(2017-07-01)
We study various semiclassical observables in the duality proposed by Guarino, Jafferis and Varela, between a warped AdS4× squashed S6 gravitational solution and a 3 dimensional N=2SYM−CSk conformal gauge theory, deformed ...
Simple recipe for holographic Weyl anomaly
(Springer Verlag, 2017-04)
We propose a recipe — arguably the simplest — to compute the holographic type-B Weyl anomaly for general higher-derivative gravity in asymptotically AdS spacetimes. In 5 and 7 dimensions we identify a suitable basis of ...
Gravity from entanglement for boundary subregions
(Springer, 2018-06)
We explore several aspects of the relation between gravity and entanglement in the context of AdS/CFT, in the simple setting of 3 bulk dimensions. Specifically, we consider small perturbations of the AdS metric and the CFT ...
Particle-vortex duality and theta terms in AdS/CMT applications
(2019-08-01)
In this paper we study particle-vortex duality and the effect of theta terms from the point of view of AdS/CMT constructions. We can construct the duality in 2+1 dimensional field theories with or without a Chern-Simons ...
Dualidade holográfica: contribuições da teoria Ads/CFT na descrição de supercondutores usuais
(Universidade Estadual Paulista (Unesp), 2018-09-28)
O objetivo desse trabalho concentra-se em estudar uma nova metodologia para resolução de problemas em matéria condensada, nos quais as partículas estão fortemente acopladas, não permitindo um tratamento perturbativo padrão. ...
