“Strange metal phases”, displaying strong deviations from Fermi liquid theory, are discussed in the context of cuprates, itinerant magnets, or heavy-fermion metals. Several Yb-based materials, e.g., -YbAlB or the Au-Al-Yb quasicrystal, display / scaling of magnetic and thermodynamic properties. This has been taken as evidence for zero-field quantum criticality without requirement to fine-tune composition and pressure. However, it appears unlikely that materials are accidentally located at such a special point in multidimensional phase space. In this paper, the authors demonstrate by a thermodynamic study on the new Kondo lattice compound YbCoGe that / scaling and a divergence of the magnetic Grüneisen parameter can arise without a quasiparticle mass divergence and in the absence of zero-field quantum criticality. They discuss alternative scenarios for such strange metal behavior.

The Kitaev model is a toy model for = moments on a honeycomb lattice, which interact via strongly bond-dependent Ising-like interactions. In real material candidates like NaIrO, small Heisenberg interactions are also present in addition to dominant Kitaev interactions. The doped Kitaev-Heisenberg model has been predicted to show unconventional superconductivity and spin or charge density wave, and bond-order instabilities. In this paper, the authors have succeeded in surface-doping NaIrO crystals by argon plasma etching and in changing the conductivity by several orders of magnitude. The doped samples show several unusual transport behaviors, including first order spin or charge density wave-like transitions.

The phenomenon of many-body localization generalizes Anderson localization to interacting systems. Understanding this conceptually novel phenomenon requires a study of many-body eigenstates at finite energy densities. This is a very challenging task since the most efficient numerical methods such as, e.g., the density matrix renormalization group method, can only access the ground state and low lying excitations. In this work, the authors introduce a unitary tensor network based variational method that approximately finds all many-body eigenstates of fully localized Hamiltonians and scales polynomially with system size. The usefulness of their approach is demonstrated by considering the Heisenberg chain in a strongly disordered magnetic field.
