Pseudogap effects on the charge dynamics in the underdoped copper oxide materials
Shiping Feng, Feng Yuan
Within the t-J model, the charge dynamics of copper oxide materials in the underdoped regime is studied based on the fermion-spin theory. It is shown that both in-plane charge dyna…

Effect of the additional second neighbor hopping on the spin dynamics in the t-J model
Xianglin Le, Feng Yuan, Shiping Feng
The effect of the additional second neighbor hopping t' on the spin dynamics in the t-J model is studied within the fermion-spin theory. Although the additional second neighbor hop…
