PPT-Technicolor Atoms

Flame Test Flame Test According to Bohr theory of the atom electrons may occupy only specific energy levels Electrons in atoms jump from their ground state to excited states by absorbing energy Eventually these electrons fall back to their ground state reemitting the absorbed energy in the form of light Because each atom has a unique structure and arrangement of electrons each atom emits a unique spectrum of light This characteristic light is the basis for the chemical test known as a flame test In this test being placed within a flame excites the atoms As they reemit the absorbed energy in the form of light the color of the flame changes For most metals these changes are easily visible However even the presence of a tiny speck of another substance can interfere with the identification of the true color of a particular type of atom .

In Amsterdam We have recently produced the first two-dimensional lattice of magnetic microtraps for ultracold atoms based on patterned magnetic films [1]. Ultracold rubidium atoms are transferred to hundreds of individual microtraps, each cloud hovering 10 micrometers above the chip surface and separated by ~20 micrometers. We are currently investigating highly excited Rydberg states of the atoms, used to mediate long-range interactions between neighbouring microtraps. This could allow entanglement of mesoscopic ensembles of atoms and paves the road toward quantum information processing with neutral atoms. We have built a dedicated laser system using 780 nm and 480 nm narrow-band diode lasers stabilised to a two-photon electromagnetically induced transparency resonance in a Rubidium vapour cell. We can excite Rydberg states from n=19 up to n~100. We have used this system to excite and image Rydberg atoms in ultracold rubidium gas confined in a surface magneto-optical trap. We are now studying the influence of the nearby (magnetic and conducting) chip surface on the Rydberg excited atoms. . . and . Periodic Table. Antoine Lavoisier.

The theory of atoms:. Original to the Greeks. Leuccipus, Democritus and Lucretius. (Aristotle thought they were nuts). He believed that one could divide up a piece of matter an infinite number of times, that is, one never came up with a piece of matter that could not be further divided. He suggested that everything in the world was made up of some combination of four elements: earth, fire, water, and air. The elements were acted upon by the two forces of gravity and levity. Gravity was the tendency for earth and water to sink, and levity the tendency for air and fire to rise.. at LHC and on the Lattice. . Koichi . Yamawaki. Nagoya University. . .
