Universal behavior of quantum spin liquid and optical conductivity in the insulator herbertsmithite
V. R. Shaginyan, A. Z. Msezane, V. A. Stephanovich +2
We analyze optical conductivity with the goal to demonstrate experimental manifestation of a new state of matter, the so-called fermion condensate. Fermion condensates are realized…
New state of matter: heavy-fermion systems, quantum spin liquids, quasicrystals, cold gases, and high temperature superconductors
V. R. Shaginyan, V. A. Stephanovich, A. Z. Msezane +6
We report on a new state of matter manifested by strongly correlated Fermi systems including various heavy-fermion (HF) metals, two-dimensional quantum liquids such as f…
The influence of topological phase transition on the superfluid density of overdoped copper oxides
V. R. Shaginyan, V. A. Stephanovich, A. Z. Msezane +2
We show that a topological quantum phase transition, generating flat bands and altering Fermi surface topology, is a primary reason for the exotic behavior of the overdoped high-te…
Strongly correlated Fermi systems as a new state of matter
V. R. Shaginyan, A. Z. Msezane, G. S. Japaridze +2
The aim of this review paper is to expose a new state of matter exhibited by strongly correlated Fermi systems represented by various heavy-fermion (HF) metals, two-dimensional liq…
Comment on "Correlated impurities and intrinsic spin liquid physics in the kagome material Herbertsmithite" (T. H. Han et al., Phys. Rev. B 94, 060409(R) (2016))
V. R. Shaginyan, M. Ya. Amusia, J. W. Clark +3
Recently Han et al. have provided an analysis of the observed behavior of Herbertsmithite based on a separation of the contributions to its thermodynamic p…
Topological basis for understanding the behavior of the heavy-fermion metal under application of magnetic field and pressure
V. R. Shaginyan, A. Z. Msezane, K. G. Popov +3
Informative recent measurements on the heavy-fermion metal performed with applied magnetic field and pressure as control parameters are analyzed with the goal of es…
