Differential neutron-hydrogen squeeze-out
The equation of state (EOS) of asymmetric nuclear matter is of fundamental importance to both nuclear physics and astrophysics. While considerable progress has been made recently in determining the symmetry energy around normal nuclear matter density [1], much more work is still needed to probe its high-density behaviour. This requires reaction studies at sufficiently high energies and probes s...
متن کامل9 Differential Neutron - Proton Squeeze - out
The elliptic flow (squeeze-out) of neutrons, protons and light complex particles in reactions of neutron-rich systems at relativistic energies is proposed as an observable sensitive to the strength of the symmetry term in the equation of state at supra-normal densities. Preliminary results from a study of the existing FOPI/LAND data for Au + Au collisions at 400 A MeV with the UrQMD model favor...
متن کاملBoundary lubrication: dynamics of squeeze-out.
The dynamics of the expulsion of the last liquid monolayer of molecules confined between two surfaces (measured recently for the first time) has been analyzed by solving the two-dimensional Navier-Stokes equation combined with kinetic Monte Carlo simulations. Instabilities in the boundary line of the expelled film were observed. We show that the instabilities produce a rough boundary for all le...
متن کاملKaon squeeze-out in heavy ion reactions
The squeeze-out phenomenon of K and K− mesons, i.e. the azimuthal asymmetry of K and K− mesons emitted at midrapidity in heavy ion reactions, is investigated for beam energies of 1-2 A.GeV. It is found that the squeeze-out signal is strongly affected by in-medium potentials of these mesons. The repulsive K-nucleus potential gives rise to a pronounced out-of-plane emission of K’s at midrapidity....
متن کاملDynamics of squeeze-out: Theory and experiments
We consider the dynamics of squeeze-out of a molecularly thin confined two-dimensional ~2D! liquidlike layer. The squeeze-out is described by a generalized 2D Navier–Stokes equation which is solved exactly for the limiting case where the squeeze-out nucleates at the center of the contact area, and where the ~perpendicular! three-dimensional pressure profile is Hertzian. We also present numerica...
