Antiferromagnetism, charge density wave, and d-wave superconductivity in the extended ---- model: role of intersite Coulomb interaction and a critical overview of renormalized mean field theory
Marcin Abram, Michał Zegrodnik, Jozef Spałek
In the first part of the paper, we study the stability of antiferromagnetic (AF), charge density wave (CDW), and superconducting (SC) states within the --- model of str…
Tricritical wings in UGe: A microscopic interpretation
Marcin Abram, Marcin M. Wysokiński, Józef Spałek
In the present work we analyze the second order transition line that connect the tricritical point and the quantum critical ending point on the temperature--magnetic-field plane in…
Criticalities in the itinerant ferromagnet UGe
Marcin M. Wysokiński, Marcin Abram, Józef Spałek
We provide a microscopic description of the magnetic properties of UGe 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…
