QUASIEXCITONS IN PHOTOLUMINESCENCE OF INCOMPRESSIBLE QUANTUM LIQUIDS
International Journal of Modern Physics B, 2007The 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, 2006In 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, 1995Abstract 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.

Implicit Density Projection for Volume Conserving Liquids
IEEE Transactions on Visualization and Computer Graphics, 2019We propose a novel implicit density projection approach for hybrid Eulerian/Lagrangian methods like FLIP and APIC to enforce volume conservation of incompressible liquids. Our approach is able to robustly recover from highly degenerate configurations and

Damping of surface waves in an incompressible liquid
Journal of Fluid Mechanics, 1957The 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, 1976The 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, 1981The 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, 2003In 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 ...

Nodal correlations in the incompressible composite fermion liquid
Physical Review B, 2003To search for possible correlations in the system of interpenetrating liquids of zeroes and electrons in the fractional quantum Hall effect, this paper studies several ground state correlation functions involving particles and zeroes in the incompressible states of composite fermions at filling factors $\ensuremath{\nu}=2/5,$ 3/7, and 4/9.
