Marginal Fermi liquid at magnetic quantum criticality from dimensional confinement
Bernhard Frank, Zi Hong Liu, Fakher F. Assaad +2
Metallic quantum criticality is frequently discussed as a source for non-Fermi liquid behavior, but controlled theoretical treatments are scarce. Here we identify and study a novel…
Magnetic quantum phase transition in a metallic Kondo heterostructure
Zi Hong Liu, Bernhard Frank, Lukas Janssen +2
We consider a two-dimensional quantum spin system described by a Heisenberg model that is embedded in a three-dimensional metal. The two systems couple via an antiferromagnetic Kon…
scaling and IR/UV-mixing in Ising-nematic quantum critical metals
Bernhard Frank, Francesco Piazza
The instability of a Fermi surface against Ising nematic order destroys the quasiparticle character of the low-energy degrees of freedom. Therefore, observables exhibit deviations…
