Electromagnetic response of high-Tc superconductors -- the slave-boson and doped-carrier theories
Tiago C. Ribeiro, Xiao-Gang Wen
We evaluate the doping dependence of the quasiparticle current and low temperature superfluid density in two slave-particle theories of the tt't''J model -- the slave-boson theory…
The short-range correlations of a doped Mott insulator
Tiago C. Ribeiro
This paper presents numerical studies of the single hole tt't''J model that address the interplay between the kinetic energy of itinerant electrons and the exchange energy of local…
The Electronic States of Two Oppositely doped Mott Insulators Bilayers
Tiago C. Ribeiro, Alexander Seidel, Jung Hoon Han +1
We study the effect of Coulomb interaction between two oppositely doped low-dimensional tJ model systems. We exactly show that, in the one-dimensional case, an arbitrarily weak int…
Doped carrier formulation and mean-field theory of the tt't''J model
Tiago C. Ribeiro, Xiao-Gang Wen
In the generalized-tJ model the effect of the large local Coulomb repulsion is accounted for by restricting the Hilbert space to states with at most one electron per site. In this…
Tunneling spectra of layered strongly correlated d-wave superconductors
Tiago C. Ribeiro, Xiao-Gang Wen
Tunneling conductance experiments on cuprate superconductors exhibit a large diversity of spectra that appear in different nano-sized regions of inhomogeneous samples. In this lett…
New mean field theory of the tt't''J model applied to the high-Tc superconductors
Tiago C. Ribeiro, Xiao-Gang Wen
We introduce a new mean field approach to the tt't''J model that incorporates both electron-like quasiparticle and spinon excitations as suggested by some experiments and numerical…
