Behavior of second order phase transitions at a quantum critical point
V. R. Shaginyan, M. Ya. Amusia, K. G. Popov
Low-temperature specific-heat measurements on YbRh2Si2 at the second order antiferromagnetic (AF) phase transition reveal a sharp peak at TN=72 mK. The corresponding critical expon…
Strongly correlated Fermi-systems: non-Fermi liquid behavior, quasiparticle effective mass and their interplay
V. R. Shaginyan, M. Ya. Amusia, K. G. Popov
Basing on the density functional theory of fermion condensation, we analyze the non-Fermi liquid behavior of strongly correlated Fermi-systems such as heavy-fermion metals. When de…
Quantum critical point in high-temperature superconductors
V. R. Shaginyan, M. Ya. Amusia, K. G. Popov +1
Recently, in high-T_c superconductors (HTSC), exciting measurements have been performed revealing their physics in superconducting and pseudogap states and in normal one induced by…
Energy scales and magnetoresistance at a quantum critical point
V. R. Shaginyan, M. Ya. Amusia, A. Z. Msezane +2
The magnetoresistance (MR) of CeCoIn_5 is notably different from that in many conventional metals. We show that a pronounced crossover from negative to positive MR at elevated temp…
The Theory of Fermi Condensate Quantum Phase Transition
Konstantin Popov
This report is devoted to the building of the theory and analyzing the phenomenon which take place in such strong correlated Fermi systems as High temperature superconductors, meta…
Asymmetric tunneling, Andreev reflection and dynamic conductance spectra in strongly correlated metals
V. R. Shaginyan, K. G. Popov
Landau Fermi liquid theory predicts that the differential conductivity between metallic point and metal is a symmetric function of voltage bias V. This symmetry holds if the partic…
