Scaling of cosmological domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We describe the results of the largest and most accurate three-dimensional field theory simulations of domain wall networks with junctions. We consider a previously introduced clas…
A gravito-electromagnetic analogy based on tidal tensors
L. Filipe Costa, Carlos A. R. Herdeiro
We propose a new approach to a physical analogy between General Relativity and Electromagnetism, based on tidal tensors of both theories. Using this approach we write a covariant f…
Eikonal Approximation in AdS/CFT: Conformal Partial Waves and Finite N Four-Point Functions
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We introduce the impact-parameter representation for conformal field theory correlators of the form A ~ < O_1 O_2 O_1 O_2 >. This representation is appropriate in the eikonal kinem…
Coisotropic embeddings in Poisson manifolds
A. S. Cattaneo, M. Zambon
We consider existence and uniqueness of two kinds of coisotropic embeddings and deduce the existence of deformation quantizations of certain Poisson algebras of basic functions. Fi…
Biased bilayer graphene: semiconductor with a gap tunable by electric field effect
Eduardo V. Castro, K. S. Novoselov, S. V. Morozov +6
We demonstrate that the electronic gap of a graphene bilayer can be controlled externally by applying a gate bias. From the magneto-transport data (Shubnikov-de Haas measurements o…
The evolution of clusters in the CLEF cosmological simulation: X-ray structural and scaling properties
Scott T. Kay, Antonio C. da Silva, Nabila Aghanim +5
We present results from a study of the X-ray cluster population that forms within the CLEF cosmological hydrodynamics simulation, a large N-body/SPH simulation of the Lambda CDM co…
