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 . This equilibrium property holds if the ows are nearly independent and it is violated by trac changes caused by several potentially small correlated ows Many trac anomalies both malicious and benign t this descrip tion Based on this observation we ex Physical Science.

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. . The Building Blocks of Matter. Chapter 2. Chapter Outline. 2.1 The .
