  Motivated by recent theoretical and experimental advances in quantum
simulations using alkaline earth(AE) atoms, we put forward a proposal to detect
the Kondo physics in a cold atomic system. It has been demonstrated that the
intrinsic spin-exchange interaction in AE atoms can be significantly enhanced
near a confinement-induced resonance(CIR), which facilitates the simulation of
Kondo physics. Since the Kondo effect appears only for antiferromagnetic
coupling, we find that the conductivity of such a system exhibits an asymmetry
across a resonance of spin-exchange interaction. The asymmetric conductivity
can serve as the smoking gun evidence for Kondo physics in the cold atom
context. When an extra magnetic field ramps up, the spin-exchange process near
the Fermi surface is suppressed by Zeeman energy and the conductivity becomes
more and more symmetric. Our results can be verified in the current
experimental setup.
