Intrinsic Geometry of a Null Hypersurface [PDF]

, 2000
We apply Cartan's method of equivalence to construct invariants of a given null hypersurface in a Lorentzian space-time. This enables us to fully classify the internal geometry of such surfaces and hence solve the local equivalence problem for null ...

Analysis of anisotropic flow with Lee-Yang zeroes [PDF]

, 2003
We present a new method to extract anisotropic flow in heavy ion collisions from the genuine correlation among a large number of particles. Anisotropic flow is obtained from the zeroes in the complex plane of a generating function of azimuthal ...

The baryon mass function for galaxy clusters [PDF]

, 2006
Context: The evolution of the cluster abundance with redshift is known to be a powerful cosmological constraint when applied to X-ray clusters. Recently, the evolution of the baryon mass function has been proposed as a new variant that is free of the ...

Energy Correlations In Random Transverse Field Ising Spin Chains [PDF]

, 2003
The end-to-end energy - energy correlations of random transverse-field quantum Ising spin chains are computed using a generalization of an asymptotically exact real-space renormalization group introduced previously.

Transit timing to first order in eccentricity [PDF]

, 2016
Characterization of transiting planets with transit timing variations (TTVs) requires understanding how to translate the observed TTVs into masses and orbital elements of the planets.

Tuning the Magnetic Ordering Temperature of Hexagonal Ferrites by Structural Distortion Control [PDF]

, 2018
To tune the magnetic properties of hexagonal ferrites, a family of magnetoelectric multiferroic materials, by atomic-scale structural engineering, we studied the effect of structural distortion on the magnetic ordering temperature (TN).

Application of a Two-Parameter Quantum Algebra to Rotational Spectroscopy of Nuclei [PDF]

, 1996
A two-parameter quantum algebra $U_{qp}({\rm u}_2)$ is briefly investigated in this paper. The basic ingredients of a model based on the $U_{qp}({\rm u}_2)$ symmetry, the $qp$-rotator model, are presented in detail.

Halo Mass Functions in Early Dark Energy Cosmologies

, 2008
We examine the linear density contrast at collapse time, $\delta_c$ for large-scale structure in dynamical dark energy cosmologies, including models with early dark energy.

On the convexity of injectivity domains on nonfocal manifolds [PDF]

, 2014
Given a smooth nonfocal compact Riemannian manifold, we show that the so-called Ma--Trudinger--Wang condition implies the convexity of injectivity domains.

On the Average Comoving Number Density of Halos

, 2006
I compare the numerical multiplicity function given in Yahagi, Nagashima & Yoshii (2004) with the theoretical multiplicity function obtained by means of the excursion set model and an improved version of the barrier shape obtained in Del Popolo & Gambera
