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.…
Unusual heat transport in underdoped cuprates
Tianxing Ma, Shiping Feng
Within the t-J model, the heat transport of the underdoped cuprates is studied based on the fermion-spin theory. It is shown that at low temperatures the energy dependence of the t…
Gauge invariant dressed holon and spinon in doped cuprates
Shiping Feng, Tianxing Ma, Jihong Qin
We develop a partial charge-spin separation fermion-spin theory implemented the gauge invariant dressed holon and spinon. In this novel approach, the physical electron is decoupled…
Unusual charge transport and spin response of doped bilayer triangular antiferromagnets
Ying Liang, Tianxing Ma, Shiping Feng
Within the t-J model, the charge transport and spin response of the doped bilayer triangular antiferromagnet are studied by considering the bilayer interaction. Although the bilaye…
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…
A gauge invariant dressed holon and spinon description of the normal-state of underdoped cuprates
Shiping Feng, Jihong Qin, Tianxing Ma
A partial charge-spin separation fermion-spin theory is developed to study the normal-state properties of the underdoped cuprates. In this approach, the physical electron is decoup…
