Behavior of the antiferromagnetic phase transition near the fermion condensation quantum phase transition in YbRh2Si2
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 T_N=72 mK. The corresponding critical expo…
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…
Magnetic-field-induced reentrance of Fermi-liquid behavior and spin-lattice relaxation rates in YbCu_{5-x}Au_x
V. R. Shaginyan, A. Z. Msezane, K. G. Popov +1
A strong departure from Landau-Fermi liquid (LFL) behavior have been recently revealed in observed anomalies in both the magnetic susceptibility and the muon and …
