Kondo physics in the algebraic spin liquid

Ki-Seok Kim, Mun Dae Kim

We study Kondo physics in the algebraic spin liquid, recently proposed to describe $Z n C u_{3} (O H)_{6} C l_{2}$ [Phys. Rev. Lett. {\bf 98}, 117205 (2007)]. Although spin dynamics of th…

Spin-gapped incoherent metal with preformed pairing in the doped antiferromagnetic Mott insulator

Ki-Seok Kim, Mun Dae Kim

We investigate how the antiferromagnetic Mott insulator evolves into the d-wave BCS superconductor through hole doping. Allowing spin fluctuations in the strong coupling approach,…
