Abstract: The Kondo effect underpins a large body of recent developments in the physicsof $d$- and $f$-band compounds. Although its {\it charge} analog is a rarity insolids, the recent observations of the charge Kondo effect and the consequentrise in superconducting T$c$ encourage a search for other accessible systems.Motivated by the possibility of wilfully tuning the {\it sign} of theinter-electronic interaction in optical lattices, we study conditions for theelusive {\it charge Kondo liquid} CKL state to manifest. We propose that acombination of Feshbach resonances and sequentially controlled laser pulses mayproduce the CKL. We show that the CKL is {\it never} a stable ground state,appearing only when the ordered ground states are destabilized. Finally, wediscuss interesting analogies with nuclear matter.
