Particle migration in pressure-driven flow of a Brownian suspension
Shear induced particle migration of 2 μm diameter spherical colloidal particles flowing through rectangular capillary tubes (50 μm × 500 μm cross section) is studied by confocal microscopy. The confocal microscope allows imaging of the flowing particles far from the walls of the tube, at particle velocities up to 8000 μm s−1. The particle volume fraction is varied from φ = 0.05–0.34, and the fl...
متن کاملFour-particle condensate in strongly coupled fermion systems
Four-particle correlations in fermion systems at finite temperatures are investigated with special attention to the formation of a condensate. Instead of the instability of the normal state with respect to the onset of pairing described by the Gorkov equation, a new equation is obtained which describes the onset of quartetting. Within a model calculation for symmetric nuclear matter, we find th...
متن کاملDrag Reduction by Surfactant Solutions in Gravity Driven Flow Systems
Efflux time measurements are carried out for gravity draining of a liquid from a large cylindrical tank (where the flow is essentially laminar) through single exit pipe in the absence and presence of Cetyl Pyridinium Chloride (CPC) surfactant solutions. The variables considered are initial height of liquid in the tank, dia. of tank, length of the exit pipe and concentration of surfactant. T...
متن کاملDecay of entanglement in coupled, driven systems with bipartite decoherence
We analyze a system of two qubits embedded in two different environments. The qubits are coupled to each other and driven on-resonance by two external classical sources. In the secular limit, we obtain exact analytical results for the evolution of the system for several classes of two-qubit mixed initial states. For Werner states we show that the decay of entanglement does not depend on couplin...
متن کاملNonlinearly driven transverse synchronization in coupled chaotic systems
Synchronization transitions are investigated in coupled chaotic maps. Depending on the relative weight of linear versus nonlinear instability mechanisms associated to the single map two different scenarios for the transition may occur. When only two maps are considered we always find that the critical coupling εl for chaotic synchronization can be predicted within a linear analysis by the vanis...
