Finite Volume Spectrum of 2D Field Theories from Hirota Dynamics
Nikolay Gromov, Vladimir Kazakov, Pedro Vieira
We propose, using the example of the O(4) sigma model, a general method for solving integrable two dimensional relativistic sigma models in a finite size periodic box. Our starting…
Bifurcation and pattern changing with two real scalar fields
P. P. Avelino, D. Bazeia, R. Menezes +1
This work deals with bifurcation and pattern changing in models described by two real scalar fields. We consider generic models with quartic potentials and show that the number of…
p-brane dynamics in N+1-dimensional FRW universes
P. P. Avelino, R. Menezes, L. Sousa
We study the evolution of maximally symmetric -branes with a $S_{p-i}\otimes \mathbbm{R}^i$ topology in flat expanding or collapsing homogeneous and isotropic universes with $N+…
Black Holes as Lumps of Fluid
Marco M. Caldarelli, Oscar J. C. Dias, Roberto Emparan +1
The old suggestive observation that black holes often resemble lumps of fluid has recently been taken beyond the level of an analogy to a precise duality. We investigate aspects of…
Non-Abelian bundles on heterotic non-compact K3 orbifold blowups
Stefan Groot Nibbelink, Filipe Paccetti Correia, Michele Trapletti
Instantons on Eguchi-Hanson spaces provide explicit examples of stable bundles on non-compact four dimensional C^2/Z_n orbifold resolutions with non-Abelian structure groups. With…
Gravitational radiation in d>4 from effective field theory
Vitor Cardoso, Oscar J. C. Dias, Pau Figueras
Some years ago, a new powerful technique, known as the Classical Effective Field Theory, was proposed to describe classical phenomena in gravitational systems. Here we show how thi…
The all loop AdS4/CFT3 Bethe ansatz
Nikolay Gromov, Pedro Vieira
We propose a set of Bethe equations yielding the full asymptotic spectrum of the AdS4/CFT3 duality proposed in arXiv:0806.1218 to all orders in the t'Hooft coupling. These equation…
The AdS4/CFT3 algebraic curve
Nikolay Gromov, Pedro Vieira
We present the OSp(2,2|6) symmetric algebraic curve for the AdS4/CFT3 duality recently proposed in arXiv:0806.1218. It encodes all classical string solutions at strong t'Hooft coup…
Efficient precision quantization in AdS/CFT
Nikolay Gromov, Sakura Schafer-Nameki, Pedro Vieira
Understanding finite-size effects is one of the key open questions in solving planar AdS/CFT. In this paper we discuss these effects in the AdS_5xS^5 string theory at one-loop in t…
HKT Geometry and de Sitter Supergravity
Jai Grover, Jan B. Gutowski, Carlos A. R. Herdeiro +1
Solutions of five dimensional minimal de Sitter supergravity admitting Killing spinors are considered. It is shown that the "timelike'' solutions are determined in terms of a four…
Toy models for wrapping effects
Joao Penedones, Pedro Vieira
The anomalous dimensions of local single trace gauge invariant operators in N=4 supersymmetric Yang-Mills theory can be computed by diagonalizing a long range integrable Hamiltonia…
A Double Myers-Perry Black Hole in Five Dimensions
Carlos A. R. Herdeiro, Carmen Rebelo, Miguel Zilhao +1
Using the inverse scattering method we construct a six-parameter family of exact, stationary, asymptotically flat solutions of the 4+1 dimensional vacuum Einstein equations, with U…
Quantum Wrapped Giant Magnon
Nikolay Gromov, Sakura Schafer-Nameki, Pedro Vieira
Understanding the finite-size corrections to the fundamental excitations of a theory is the first step towards completely solving for the spectrum in finite volume. We compute the…
Eikonal Methods in AdS/CFT: BFKL Pomeron at Weak Coupling
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones
We consider correlators of N=4 super Yang Mills of the form A ~ < O_1 O_2 O*_1 O*_2 >, where the operators O_1 and O_2 are scalar primaries. In particular, we analyze this correlat…
