Thermal conductivity in the doped two-leg ladder antiferromagnet SrCaCuO
Jihong Qin, Shiping Feng, Feng Yuan +1
Within the t-J model, the heat transport of the doped two-leg ladder material SrCaCuO is studied in the doped regime where superconductivity appears un…
Charge transport of electron doped Mott insulators on a triangular lattice
Bin Liu, Ying Liang, Shiping Feng +1
The charge transport of electron doped Mott insulators on a triangular lattice is investigated within the t-J model based on the partial charge-spin separation fermion-spin theory.…
Charge transport in underdoped bilayer cuprates
Feng Yuan, Jihong Qin, Shiping Feng +1
Within the t-J model, we study the charge transport in underdoped bilayer cuprates by considering the bilayer interaction. Although the bilayer interaction leads to the band splitt…
Energy dependence of commensurate neutron scattering peak in doped two-leg ladder antiferromagnet Sr_{14-x}Ca_{x}Cu_{24}O_{41}
Jianhui He, Shiping Feng, Wei Yeu Chen
The dynamical spin response of doped two-leg ladder antiferromagnets is investigated based on the fermion-spin approach. Our calculations clearly demonstrate a crossover from the i…
