1. Apparatus for studying Fermi-Fermi-Bose mixtures in optical lattices We have completed the assembly of a new apparatus that can simultaneously cool and trap two different fermionic species, Li and K, as well as K. The cold atom sources are also able to provide Rb and Na in the future. One major interest lies in the creation of heteronuclear, stable ground-state molecules that carry a strong ...

NO and CO are small gaseous molecules that can be synthesized de novo in neuronal tissue and can diffuse readily through the plasma membrane. NOS inhibitors prevent the induction of LTP in the hippocampus, and studies with NOS knock-out mice and viral overexpression of mutated NOS indicate that the endothelial form of the enzyme is probably responsible for NO production in these neurons. Inhibi...

aerosol A colloidal dispersion of liquid particles in a gas, e.g., SO2, which will react with the OH radical in the atmosphere to form tiny droplets of sulfuric acid (H2SO4). hazard In a volcanic context, hazard refers to the phenomena produced by a volcanic event and is directly related to Risk, where Risk1⁄4Hazard Vulnerability, with vulnerability referring to the consequences for population ...

Molecule formation in ultracold degenerate quantum gases is one of the central topics in the overall ACQAO program, due to the strong quantum correlations in these systems. An experimental program in ultra-cold molecule formation using fermionic Li near a Feshbach resonance is underway at the SUT node of ACQAO. The work described here provides theoretical support for possible experimental inves...

In this work we study the behavior of relativistic ideal Bose and Fermi gases in two space dimensions. Making use of polylogarithm functions we derive a closed and unified expression for their densities. It is shown that both type of gases are essentially inequivalent, and only in the non-relativistic limit the spinless and equal mass Bose and Fermi gases are equivalent as known in the literature.

The decay of the plasma grating formed at the intersection of two femtosecond filaments is measured in several molecular and atomic gases. The grating evolution is ruled by ambipolar diffusion in atomic gases and by a combination of ambipolar diffusion and collision-assisted free electron recombination in molecular gases. Electron diffusion and recombination coefficients are extracted for Ne, A...

Batch culture of Ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. The gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

We report two-dimensional 2D electron and hole gases induced at the surface of graphite by the electric field effect. The 2D gases reside within a few near-surface atomic layers and exhibit mobilities up to 15 000 and 60 000 cm2/V s at room and liquid-helium temperatures, respectively. The mobilities imply ballistic transport on m scale. Pronounced Shubnikov–de Haas oscillations reveal the exis...

Recent developments in the physics of ultracold gases provide wide possibilities for reducing the dimensionality of space for magnetically or optically trapped atoms. The goal of these lectures is to show that regimes of quantum degeneracy in two-dimensional (2D) and one-dimensional (1D) trapped gases are drastically different from those in three dimensions and to stimulate an interest in low-d...
