Electron spectrum, thermodynamics and transport in antiferromagnetic metals at low temperatures
V. Yu. Irkhin, M. I. Katsnelson
Electron spectrum of 2D and 3D antiferromagnetic metals is calculated with account of spin-fluctuation corrections within perturbation theory in the s-f exchange model. Effects of…
Structure, elastic moduli and thermodynamics of sodium and potassium at ultra-high pressures
M. I. Katsnelson, G. V. Sinko, N. A. Smirnov +2
The equations of state at room temperature as well as the energies of crystal structures up to pressures exceeding 100 GPa are calculated for Na and K . It is shown that the allowa…
Breakdown of Luttinger liquid state in one-dimensional frustrated spinless fermion model
A. K. Zhuravlev, M. I. Katsnelson
Haldane hypothesis about the universality of Luttinger liquid (LL) behavior in conducting one-dimensional (1D) fermion systems is checked numerically for spinless fermion model wit…
Spin-wave contributions to nuclear magnetic relaxation in magnetic metals
V. Yu. Irkhin, M. I. Katsnelson
The longitudinal and transverse nuclear magnetic relaxation rates and are calculated for three- and two-dimensional (3D and 2D) metallic ferro- and antiferrom…
Non-Fermi-liquid behavior in the Kondo lattices induced by peculiarities of magnetic ordering and spin dynamics
V. Yu. Irkhin, M. I. Katsnelson
A scaling consideration of the Kondo lattices is performed with account of singularities in the spin excitation spectral function. It is shown that a non-Fermi-liquid (NFL) behavio…
