Abstract in English
We discuss the coexistence of antiferromagnetism and d-wave superconductivity within the so-called statistically consistent Gutzwiller approximation (SGA) applied to the t–J–U model. In this approach, the averages calculated in a self-consistent manner coincide with those determined variationally. Such consistency is not guaranteed within the standard renormalized mean-field theory. With the help of SGA, we show that for the typical value
