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…
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…
