Spectral Functions and Pseudogap in Models of Strongly Correlated Electrons
P. Prelovsek, A. Ramsak
The theoretical investigation of spectral functions and pseudogap in systems with strongly correlated electrons is discussed, with the emphasis on the single-band t-J model as rele…

Spectral properties of underdoped cuprates
A. Ramsak, P. Prelovsek, I. Sega
In the framework of the planar t-J model for cuprates we analyze the development of a pseudo gap in the density of states, which at low doping starts to emerge for temperatures T<J…
