Growth of spinodal instabilities in nuclear matter

Yılmaz, Osman
Early growth of density fluctuations of nuclear matter in the spinodal region is investigated employing the stochastic mean-field approach. In contrast to the earlier treatments in which only collective modes were included in the calculations, in the present work noncollective modes are also included, thus providing a complete treatment of the density correlation functions. Calculations are carried out for symmetric matter in a nonrelativistic framework using a semiclassical approximation.

ACAR, FERİDE PINAR; Ayik, S.; Yılmaz, Osman; GÖKALP, AHMET (2015-09-11)
As an extension of our previous work, the growth of density fluctuations in the spinodal region of charge asymmetric nuclear matter is investigated in the basis of the stochastic mean-field approach in the nonrelativistic framework. A complete treatment of density correlation functions is presented by including collective modes and noncollective modes.
Quantal effects on spinodal instabilities in charge asymmetric nuclear matter
Ayik, S.; Er, N.; Yılmaz Tüzün, Özgül; Gokalp, A. (Elsevier BV, 2008-11-01)
Quantal effects on growth of spinodal instabilities in charge asymmetric nuclear matter are investigated in the framework of a stochastic mean field approach. Due to quantal effects, in both symmetric and asymmetric matter, dominant unstable modes shift towards longer wavelengths and modes with wave numbers larger than the Fermi momentum are strongly suppressed. As a result of quantum statistical effects, in particular at lower temperatures, magnitude of density fluctuations grows larger than those calculat...
Investigation of acetyl ferrocene migration from hydroxyl-terminated polybutadiene based elastomers by means of ultraviolet-visible and atomic absorption spectroscopic techniques
Unver, A; Dilsiz, N; Volkan, Mürvet; Akovali, G (Wiley, 2005-06-05)
Migration and leakage of some mobile components in rocket propellant produces an inhomogeneous composition region at which migration takes place, which can lead to premature detonation, changes in ballistic characteristics, and so on. It is, therefore, important to be able to predict the behavior of low-molecular-weight mobile additives and to control the leakage of them from the propellant. At this point, our chief interest was to study the magnitude of the migration and to understand the factors that infl...
Spinodal instabilities in symmetric nuclear matter within a density-dependent relativistic mean-field approach
Danışman, Betül; Yılmaz, Osman; Department of Physics (2011)
The nuclear matter liquid-gas phase transition is expected to be a signal of nuclear spinodal instabilities as a result of density fluctuations. Nuclear spinodal instabilities in symmetric nuclear matter are studied within a stochastic relativistic density-dependent model in semi-classical approximation. We use two parameterization for the Lagrange density, DDME1 and TW sets. The early growth of density fluctuations is investigated by employing relativistic Vlasov equation based on QHD and discussed the clu...
Identification of morphometric properties of basins located on western part of NAFZ
Sarp, Gülcan; Toprak, Vedat; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2012)
This study aims to investigate tectonic activity levels and development stages of the tectonic and hydrologic basin areas located on western part of the main trace of the North Anatolian Fault Zone (NAFZ) using quantitative measurement techniques. The basins investigated are Bolu, Yeniçağa, Dörtdivan, Çerkes, Ilgaz and Tosya. The methodology includes application of six morphometric indices (Basin Shape, Hypsometric curve and Hypsometric Integral, Sinuosity of Mountain Fronts, Stream Length Gradient Index, V...
