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…
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…
Magnetoresistance of the heavy-fermion metal CeCoIn5
V. R. Shaginyan, K. G. Popov
The magnetoresistance (MR) of CeCoIn5 is notably different from that expected for orbital MR due to the Lorentz force and described by Kohler's rule which holds in many conventiona…
Universal Behavior of Two-Dimensional 3He at Low Temperatures
V. R. Shaginyan, A. Z. Msezane, K. G. Popov +1
On the example of two-dimensional (2D) 3He we demonstrate that the main universal features of its experimental temperature T - density x phase diagram [see M. Neumann, J. Nyéki, J.…
