Kondo effect in alkaline-earth-metal atomic gases with confinement-induced resonances

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

We demonstrate that laser excitations can coherently induce a novel Kondo effect in ultracold atoms in optical lattices. Using a model of alkaline-earth fermions with two orbitals, it is shown that the optically coupled two internal states are dynamically entangled to form the Kondo-singlet state, overcoming the heating effect due to the irradiation. Furthermore, a lack of SU(N) symmetry in the...

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

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...

Quantum computing with alkaline-Earth-metal atoms.

We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...

Magnetic crystals and helical liquids in alkaline-earth fermionic gases

The joint action of a magnetic field and of interactions is crucial for the appearance of exotic quantum phenomena, such as the quantum Hall effect. Owing to their rich nuclear structure, equivalent to an additional synthetic dimension, one-dimensional alkaline-earth(-like) fermionic gases with synthetic gauge potential and atomic contact repulsion may display similar related properties. Here w...
