Magnetic structures of quaternary intermetallic borocarbides RCo2B2C (R=Dy, Ho, Er)

M. ElMassalami, R. Moreno, H. Takeya +3

The magnetic structures of the title compounds have been studied by neutron diffraction. In contrast to the isomorphous RNi2B2C compounds wherein a variety of exotic incommensurate…

-Koszul algebras, 2- determined algebras and 2--Koszul algebras

Edward L. Green, Eduardo do N. Marcos

The relationship between an algebra and its associated monomial algebra is investigated when at least one of the algebras is -Koszul. It is shown that an algebra which has a red…

An Accelerating Cosmology Without Dark Energy

G. Steigman, R. C. Santos, J. A. S. Lima

The negative pressure accompanying gravitationally-induced particle creation can lead to a cold dark matter (CDM) dominated, accelerating Universe (Lima et al. 1996) without requir…

NeXSPheRIO results on azimuthal anisotropy in Au-Au collisions at 200A GeV

Wei-Liang Qian, Rone Andrade, Arthur dos Reis +3

In this work, we present the results obtained by the hydrodynamic code NeXSPheRIO on anisotropic flows. In our calculation, we made use of event-by-event fluctuating initial condit…

Tightened Lieb-Oxford bound for systems of fixed particle number

Mariana M. Odashima, K. Capelle, S. B. Trickey

The Lieb-Oxford bound is a constraint upon approximate exchange-correlation functionals. We explore a non-empirical tightening of that bound in both universal and electron-number-d…
