Evolution of the Kondo lattice and non-Fermi liquid excitations in a heavy-fermion metal
Evolution of the Kondo lattice and non-Fermi liquid excitations in a heavy-fermion metal
Strong electron correlations can give rise to extraordinary properties of metals with renormalized Landau quasiparticles. Near a quantum critical point, these quasiparticles can be destroyed and non-Fermi liquid behavior ensues. YbRh2Si2 is a prototypical correlated metal exhibiting the formation of quasiparticle and Kondo lattice coherence, as well as quasiparticle destruction …
