t-t'-J-U model in mean-field approximation: Coexistence of superconductivity and antiferromagnetism

Marcin Abram

We discuss the $t$ - $J$ - $U$ model in the mean-field approximation. The role of spin-exchange coupling $J$ and the second nearest hopping $t^{'}$ are examined in the context of the coex…

Criticalities in the itinerant ferromagnet UGe $_{2}$

Marcin M. Wysokiński, Marcin Abram, Józef Spałek

We provide a microscopic description of the magnetic properties of UGe $_{2}$ and in particular, of its both classical and quantum critical behavior. Namely, we account for all the cr…

Ferromagnetism in UGe2 : A microscopic model

Marcin M. Wysokiński, Marcin Abram, Jozef Spałek

Anderson lattice model is used to rationalize the principal features of the heavy fermion compound UGe2 by means of the generalized Gutzwiller approach (the SGA method). This micro…
