Probing the Kondo lattice model with alkaline-earth-metal atoms
Physical Review A—Atomic, Molecular, and Optical Physics, 2010•APS
We study transport properties of alkaline-earth-metal atoms governed by the Kondo lattice
Hamiltonian plus a harmonic confining potential, and suggest simple dynamical probes of
several different regimes of the phase diagram that can be implemented with current
experimental techniques. In particular, we show how Kondo physics at strong coupling, at
low density, and in the heavy fermion phase is manifest in the dipole oscillations of the
conduction band upon displacement of the trap center.
