Cluster formation in quantum critical systems

Tom Heitmann, John Gaddy, Jagat Lamsal +1

The presence of magnetic clusters has been verified in both antiferromagnetic and ferromagnetic quantum critical systems. We review some of the strongest evidence for strongly dope…

Modified percolation theory and its relevance to quantum critical phenomena

Tom Heitmann, John Gaddy, Wouter Montfrooij

We present the results of a percolation-like model that has been restricted compared to standard percolation models in the sense that we do not allow finite sized clusters to break…

Comment on "Evidence for a non Fermi liquid phase in Ge-substituted YbRh $_{2}$ Si $_{2}$ "

John Gaddy, Tom Heitmann, Jagat Lamsal +1

In a recent paper, Custers {\it et al.} \cite{custers} argue for the existence of a new metallic quantum critical phase at 0 K in the Ge-doped heavy-fermion system YbRh $_{2}$ Si $_{2}$ i…

Magnetic excitations in the spinel compound Li $_{x}$ [Mn $_{1.96}$ Li $_{0.04}$ ]O $_{4}$ (x= 0.2, 0.6, 0.8, 1.0): how a classical system can mimic quantum critical scaling

Thomas Heitmann, Alexander Schmets, John Gaddy +4

We present neutron scattering results on the magnetic excitations in the spinel compounds Li $_{x}$ [Mn $_{1.96}$ Li $_{0.04}$ ]O $_{4}$ (x= 0.2, 0.6, 0.8, 1.0). We show that the dominant exc…
