Matter in the universe has become “dark” or “missing” through misconceptions about the fluid mechanics of gravitational structure formation. The linear Jeans (1902, 1929) theory gives vast overestimates (by factors of trillions or more) for the initial condensation mass of baryonic matter, and vast underestimates (by factors of trillions or more) for the initial condensation mass of the non-bar...

Jeans’s (1902 & 1929) gravitational instability criterion gives truly spectacular errors in its predictions of cosmological structure formation according to Gibson’s (1996) new theory. It is suggested that the linear perturbation stability analysis leading to the acoustic Jeans length scale criterion L ≥ LJ ≡ Vs/(ρG) 1/2 is quite irrelevant to gravitational condensation, which is intrinsically ...

A new technique is described to study the condensation of supersaturated vapors on nanoparticles under well-defined conditions of vapor supersaturation, temperature, and carrier gas pressure. The method is applied to the condensation of supersaturated trifluoroethanol (TFE) vapor on Mg nanoparticles. The nanoparticles can be activated to act as condensation nuclei at supersaturations significan...

We describe several experimental studies of Bose-Einstein condensation in a dilute gas of sodium atoms. These include studies of static and dynamic behavior of the condensate, and of its coherence properties.

We present a rigorous study of the Bose-Einstein condensation in the Luttinger-Sy model. We prove the existence of the condensation in this one-dimensional model of the perfect boson gas placed in the Poisson random potential of singular point impurities. To tackle the off-diagonal long-range order we calculate explicitly the corresponding spaceaveraged one-body reduced density matrix. We show ...

We study the accretion flow of a hot gas captured by the black hole gravity in the presence of a thin cold accretion disk. Such geometrical arrangement is expected in Active Galactic Nuclei (AGN) and in galactic X-ray binary systems because both hot and cold gases are present in the black hole vicinity. Previous astrophysical literature concentrated on the evaporation of the cold disk in the cl...

[1] Simulating gas/particle mass transfer in three-dimensional (3-D) air quality models (AQMs) represents one of the major challenges for both hindcasting and forecasting. The lack of an efficient yet accurate gas/particle mass transfer treatment for aerosol simulation and forecast in 3-D AQMs warrants its development, improvement, and evaluation. In this paper, several condensation/evaporation...

We have created one-, two-, and three-dimensional quantum gases and study the superfluid to Mott insulator transition. Measurements of the transition using Bragg spectroscopy show that the excitation spectra of the low-dimensional superfluids differ significantly from the three-dimensional case. A low dimensional gas can be created in a trap when the confining potential restricts the motion of ...
