Green's function variational approach to orbital polarons in KCuF3

Krzysztof Bieniasz, Mona Berciu, Maria Daghofer +1

We develop an $e_{g}$ orbital, $t$ - $J$ -like model of a single charge doped into a two-dimensional plane with ferromagnetic spin order and alternating orbital order, and present its s…

The Green function variational approximation: Significance of physical constraints

Krzysztof Bieniasz, Mona Berciu, Andrzej M. Oleś

We present a calculation of the spectral properties of a single charge doped at a Cu( $3 d$ ) site of the Cu-F plane in KCuF $_{3}$ . The problem is treated by generating the equations…
