Effective field theory for hydrodynamics: Wess-Zumino term and anomalies in two spacetime dimensions
Effective field theory hydrodynamics:anomalies spacetime dimensions
2011/10/14
We develop the formalism that incorporates quantum anomalies in the effective field theory of non-dissipative fluids. We consider the effect of adding a Wess-Zumino-like term to the low-energy effecti...
The Voronoi Tessellation cluster finder in 2+1 dimensions
Cosmology observations – Galaxies: clusters general – Methods data analysis
2010/11/16
We present a detailed description of the Voronoi Tessellation (VT) cluster finder algorithm in 2+1 dimensions, which improves on past implementations of this technique. The need for cluster finder alg...
Propagation of an Earth-directed coronal mass ejection in three dimensions
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP) Plasma Physics (physics.plasm-ph) Space Physics (physics.space-ph)
2010/12/23
Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood. Whil...
Hydrodynamical Neutron Star Kicks in Three Dimensions
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Phenomenology (hep-ph)
2010/12/23
Using three-dimensional (3D) simulations of neutrino-powered supernova explosions we show that the hydrodynamical kick scenario proposed by Scheck et al. on the basis of two-dimensional (2D) models ca...
Einstein-Cartan gravity excludes extra dimensions
Riemann-Cartan weak/Planck hierarchy gravity
2010/3/19
We show that the electron in the Riemann-Cartan spacetime with extra dimensions has a finite size that is much larger than the experimental upper limit on its radius. Thus the Arkani-Hamed-Dimopoulos-...
Large Extra Dimensions and Small Black Holes at the LHC
Black Holes Dimensions mass-scale M
2010/3/19
We present an overview on the conjectured production of microscopic black holes as a consequence of high energy hadronic collisions at the LHC, CERN (Geneva, Switzerland) from this year on. Provided t...
Need of Dark Energy for Dynamical Compactification of Extra Dimensions on the Brane
Dark Energy Dynamical Compactification the Brane
2010/10/18
We consider a six-dimensional braneworld model and we study the cosmological evolution of a (4+1) braneuniverse. Introducing matter on the brane we show that the scale factor of the physical three-dim...
