Fermions under strong repulsion: from multiconnected Fermi surfaces to Fermi condensation
Yu. G. Pogorelov, V. R. Shaginyan
We consider a system of fermions with mass m and model repulsive interaction U(q) = g/\sqrt{q^2 + q_0^2}, where q is the momentum transfer, q_0 the screening constant, and g > 0 th…
Transition from non Fermi Liquid Behavior to Landau Fermi Liquid Behavior Induced by Magnetic Fields
Yu. G. Pogorelov, V. R. Shaginyan
We show that a strongly correlated Fermi system with the fermion condensate, which exhibits strong deviations from Landau Fermi liquid behavior, is driven into the Landau Fermi liq…
Appearance of Fermion Condensation Quantum Phase Transition in Different Fermi Liquids
V. R. Shaginyan
We show that the quasiparticle effective mass diverges as a function of the system's density , , when a system approaches the critical point $x_{F…
Model of Strongly Correlated 2D Fermi Liquids Based on Fermion-Condensation Quantum Phase Transition
V. R. Shaginyan
A theory of strongly correlated electron or hole liquids with the fermion condensate is presented and applied to the consideration of quasiparticle excitations in high temperature…
