Phase Diagram of Vertically Shaken Granular Matter
A shallow, vertically shaken granular bed in a quasi 2-D container is studied experimentally yielding a wider variety of phenomena than in any previous study: (1) bouncing bed, (2) undulations, (3) granular Leidenfrost effect, (4) convection rolls, and (5) granular gas. These phenomena and the transitions between them are characterized by dimensionless control parameters and combined in a full ...
متن کاملAttractive emulsion droplets probe the phase diagram of jammed granular matter.
It remains an open question whether statistical mechanics approaches apply to random packings of athermal particles. Although a jamming phase diagram has recently been proposed for hard spheres with varying friction, here we use a frictionless emulsion system in the presence of depletion forces to sample the available phase space of packing configurations. Using confocal microscopy, we access t...
متن کاملBifurcation diagram for compartmentalized granular gases.
The bifurcation diagram for a vibrofluidized granular gas in N connected compartments is constructed and discussed. At vigorous driving, the uniform distribution (in which the gas is equi-partitioned over the compartments) is stable. But when the driving intensity is decreased this uniform distribution becomes unstable and gives way to a clustered state. For the simplest case, N=2, this transit...
متن کاملTowards the QCD phase diagram
We summarize our recent results on the phase diagram of QCD with N f = 2+1 quark flavors, as a function of temperature T and quark chemical potential μ . Using staggered fermions, lattices with temporal extent Nt = 4, and the exact RHMC algorithm, we first determine the critical line in the quark mass plane (mu,d ,ms) where the finite temperature transition at μ = 0 is second order. We confirm ...
متن کاملThe Phase Diagram of QCD
I use simple thermodynamic reasoning to argue that at temperatures of order a trillion kelvin, QCD, the theory which describes strongly interacting particles such as protons and neutrons under normal conditions, undergoes a phase transition to a plasma of more elementary constituents called quarks and gluons. I review what is known about the plasma phase both from theoretical calculations and f...
