The quantal BoltzmannاLangevin equation is used to obtain a dispersion relation for the growth rates of instabilities in infinite nuclear matter. The dispersion relation is solved numerically for three different potentials. The quantal results are compared with the semi-classical solutions. It is seen that with the inclusion of the quantal effects the growth rates of the fastest growing modes in the system are reduced and these modes have the tendency to occur at longer wavelengths for all the potentials considered. Furthermore, the boundaries of the spinodal region is determined by the phase diagrams using the same three potentials and it is observed that the expanding nuclear matter undergoes liquid-gas phase transition at reduced temperatures when the quantum effects are included.

Quantal description of spinodal instabilities in a symmetric nuclear matter Acar Çakırca, Fatma; Yılmaz, Osman; Ayık, Şakir; Department of Physics (2017) Spinodal instability mechanism and early development of density ﬂuctuations for asymmetric hot nuclear matter produced in heavy-ion collisions are investigated in non-relativistic and relativistic stochastic mean-ﬁeld approaches. In relativistic approach, a stochastic extension of the relativistic mean-ﬁeld approximation based on non-linear Walecka model employed in a quantal framework. The mediator rho meson is added to the Walecka model in order to investigate the isospin dependence of the system. The gro...
Observation of nuclear modifications in W-+/- boson production in pPb collisions at root s(NN)=8.16 TeV Sirunyan, A. M.; et. al. (Elsevier BV, 2020-01-01) The production of W-+/- bosons is studied in proton-lead (pPb) collisions at a nucleon-nucleon centre-of-mass energy of root s(NN) = 8.16 TeV. Measurements are performed in the W-+/- -> mu(+/-)nu(mu) channel using a data sample corresponding to an integrated luminosity of 173.4 +/- 6.1 nb(-1), collected by the CMS Collaboration at the LHC. The number of positively and negatively charged W bosons is determined separately in the muon pseudorapidity region in the laboratory frame vertical bar eta(mu)(lab)verti...
Quantal diffusion approach for multinucleon transfers in Xe plus Pb collisions Ayik, S.; Yilmaz, B.; Yılmaz, Osman; Umar, A. S. (2019-07-01) Employing a quantal diffusion description based on the stochastic mean-field approach, we analyze the mass distribution of the primary fragments in the collisions of the Xe-136 + Pb-208 system at the bombarding energy E-c.m. = 526 MeV. This quantal approach provides a good description of the primary fragment distribution without any adjustable parameter, including the effects of shell structure
RPA instabilities in finite nuclei at low density Jacquot, B; Colonna, M; Ayik, S; Chomaz, P (Elsevier BV, 1997-05-12) Early development of the instabilities in a dilute nuclear source is investigated using a finite temperature quantal RPA approach for different systems, The growth rates of the unstable collective modes are determined by solving a dispersion relation, which is obtained by parametrizing the transition density in terms of its multipole moments. Under typical conditions of a dilute finite system at moderate temperatures the dispersion relation exhibits an ultraviolet cut-off. As a result, only a finite number ...
Measurement of W gamma and Z gamma production in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (Elsevier BV, 2011-07-01) A measurement of W gamma and Z gamma production in proton-proton collisions at root s = 7 TeV is presented. Results are based on a data sample recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 36 pb(-1). The electron and muon decay channels of the W and Z are used. The total cross sections are measured for photon transverse energy E-T(gamma) > 10 GeV and spatial separation from charged leptons in the plane of pseudorapidity and azimuthal angle Delta R(l.gamma) > 0.7, an...
