Composite pairings in chirally stabilized critical fluids

We study a one-dimensional electron gas in a special antiferromagnetic envi ronment made by two spin-1/2 Heisenberg chains and a one-dimensional two-ch annel Kondo-Heisenberg lattice away from half-filling. These models flow to an intermediate fixed point which belongs to the universality class of chi rally stabilized liquids. Using a Toulouse point approach, the universal pr operties of the models are determined as well as the identification of the leading instabilities. It is shown that these models exhibit a non-Fermi-li quid behavior with strong enhanced composite pairing correlations.
