Laser-Induced Kondo Effect in Ultracold Alkaline-Earth Fermions.

Title Laser-Induced Kondo Effect in Ultracold Alkaline-Earth Fermions

Multichannel Kondo approach to the cuprate and recent laser ARPES data

The existing theoretical approaches have been unable to confront the large corpus of outstanding data on the cuprate superconductor in a persuasive and unified manner. There is a general opinion now growing that these theories miss some essential points. We propose one based on multichannel Kondo effect that is physically justifiable and confronts the data adequately. In addition to earlier da...

Prospects for ultracold carbon via charge exchange reactions and laser cooled carbides.

Strategies to produce an ultracold sample of carbon atoms are explored and assessed with the help of quantum chemistry. After a brief discussion of the experimental difficulties using conventional methods, two strategies are investigated. The first attempts to exploit charge exchange reactions between ultracold metal atoms and sympathetically cooled C(+) ions. Ab initio calculations including e...

Employing confinement induced resonances to realize Kondo physics with ultracold atoms

We recently proposed a novel realization of Kondo physics with ultracold atomic gases and illustrated that a mixture of K and Na atoms has suitable properties for the generation of a Kondo-correlated state with experimentally accessible scales. This system fortuitously satisfies rather special conditions. Here we discuss an alternative realization based on confinement induced resonances which c...

Spectroscopy of Cold LiCa Molecules Formed on Helium Nanodroplets

We report on the formation of mixed alkali-alkaline earth molecules (LiCa) on helium nanodroplets and present a comprehensive experimental and theoretical study of the ground and excited states of LiCa. Resonance enhanced multiphoton ionization time-of-flight (REMPI-TOF) spectroscopy and laser induced fluorescence (LIF) spectroscopy were used for the experimental investigation of LiCa from 1500...
