Fourier-Flow model generating Feynman paths
Shile Chen, Oleh Savchuk, Shiqi Zheng +4
As an alternative but unified and more fundamental description for quantum physics, Feynman path integrals generalize the classical action principle to a probabilistic perspective,…
Phase transition amplification of proton number fluctuations in nuclear collisions from a transport model approach
O. Savchuk, R. V. Poberezhnyuk, A. Motornenko +3
The time evolution of particle number fluctuations in nuclear collisions at intermediate energies ( GeV) is studied by means of the UrQMD-3.5 transport mode…
Fluctuations in heavy ion collisions and global conservation effects
Roman V. Poberezhnyuk, Volodymyr Vovchenko, Oleh Savchuk +3
Subensemble is a type of statistical ensemble which is the generalization of grand canonical and canonical ensembles. The subensemble acceptance method (SAM) provides general formu…
Enhanced dilepton emission from a phase transition in dense matter
O. Savchuk, A. Motornenko, J. Steinheimer +4
It is demonstrated that the presence of a phase transition in heavy ion collisions, at beam energies that probe dense QCD matter, leads to a significant enhancement of the dilepton…
Possible origin of HADES data on proton number fluctuations in Au+Au collisions
O. Savchuk, R. V. Poberezhnyuk, M. I. Gorenstein
Recent data of the HADES Collaboration in Au+Au central collisions at GeV indicate large proton number fluctuations inside one unit of rapidity around midra…
Equilibration and locality
Marek Gazdzicki, Mark Gorenstein, Ivan Pidhurskyi +2
Experiments motivated by predictions of quantum mechanics indicate non-trivial correlations between spacelike-separated measurements. The phenomenon is referred to as a violation o…
Critical point influenced by Bose-Einstein condensation
V. A. Kuznietsov, O. Savchuk, O. S. Stashko +1
A system of bosons studied within the mean field framework has two fascinating phenomena: a liquid-gas first order phase transition and Bose-Einstein condensation. Interplay betwee…
Critical point particle number fluctuations from molecular dynamics
Volodymyr A. Kuznietsov, Oleh Savchuk, Mark I. Gorenstein +2
We study fluctuations of particle number in the presence of critical point by utilizing molecular dynamics simulations of the classical Lennard-Jones fluid in a periodic box. The n…
