Properties of an almost localized Fermi liquid in an applied magnetic field revisited: a statistically consistent Gutzwiller approach (original) (raw)

The paper explores the properties of almost localized Fermi liquids under the influence of an applied magnetic field, utilizing a statistically consistent Gutzwiller approach. It argues that while traditional Landau Fermi liquid theory provides a foundation for understanding fermionic interactions, it fails to capture crucial effects related to strong correlations, such as Mott localization. The findings emphasize the relevance of the almost localized Fermi liquid framework across various systems, supporting it with specific heat calculations and magnetization analyses that reveal nonlinearities and metamagnetic behavior.
