Stability of a liquid jet into incompressible gases and liquids

International Journal of Multiphase Flow, 2004
Summary: We carry out an analysis of the stability of a liquid jet into a gas or another liquid using viscous potential flow. The instability may be driven by Kelvin-Helmholtz KH instability due to a velocity difference and a neckdown due to capillary instability.

Incompressible composite fermion liquids

Physica E: Low-dimensional Systems and Nanostructures, 2008
The "second generation" fractional quantum Hall states containing a partially filled composite fermion (CF) Landau level (LL) are studied theoretically. The role of the unique form of the CF-CF interaction in the incompressibility of the underlying quantum electron liquid is explained. In particular, the two- and three-body CF correlation functions for

QUASIEXCITONS IN PHOTOLUMINESCENCE OF INCOMPRESSIBLE QUANTUM LIQUIDS

International Journal of Modern Physics B, 2007
The problem of a trion (charged exciton) immersed in an incompressible quantum liquid formed by two-dimensional electrons in a high magnetic field is studied theoretically by combining the composite fermion model and exact numerical diagonalization. Laughlin correlation of the trion with the surrounding electrons is shown to lead to the formation of a

Violation of the incompressibility of liquid by simple shear flow

Nature, 2006
In standard fluid dynamics, the density change associated with flow is often assumed to be negligible, implying that the fluid is incompressible. For example, this has been established for simple shear flows, where no pressure change is associated with flow: there is no volume deformation due to viscous stress and inertial effects can be neglected ...

Photoluminescence of excitons in the incompressible quantum liquid

Physica B: Condensed Matter, 1995
Abstract The radiative recombination time τ of excitons in GaAs/AlGaAs quantum wells shows an anomalous increase at the v = 1 3 incompressible quantum liquid (IQL). This order of magnitude increase in τ indicates that at v = 1 3 the electron density near the valence band hole is reduced.

Damping of surface waves in an incompressible liquid

Journal of Fluid Mechanics, 1957
The damping of surface waves of small amplitude in liquid contained in cylinders has been calculated. Viscous dissipation in an assumed laminar boundary layer was taken to be the primary cause of damping. Experimental results were obtained for the logarithmic decrement as a function of the ratio of liquid height to cylinder radius for several water ...

Turbulent vortex couple in an incompressible liquid

Fluid Dynamics, 1976
The automodel problem of the motion of a turbulent vortex couple and the transfer of heat by the latter is solved numerically. The singularities of the resultant solutions are analyzed for various rates of change of the turbulent viscosity coefficient.

On the Radial Oscillations of Multiple Gas Bubbles in an Incompressible Liquid

Journal of Applied Mechanics, 1981
The radial oscillations of multiple gas bubbles in an incompressible liquid bounded by plane solid or free surfaces are analyzed. Derivation of the normal mode frequencies and mode shapes of two, three, and four bubble configurations in an unbounded liquid illustrate the method of analysis.

Optical Probing of a Fractionally Charged Quasihole in an Incompressible Liquid

Physical Review Letters, 2003
In photoluminescence spectroscopy of a low-mobility two-dimensional electron gas subjected to a quantizing magnetic field, we observe an anomaly around nu= (1/3) at a very low temperature (0.1 K) and an intermediate electron density (0.9×1011 cm–2). The anomaly is explained as due to perturbation of the incompressible liquid at the Laughlin state due ...
