ω/T scaling and magnetic quantum criticality in BaFe2(As0.7P0.3)2
Ding Hu, Haoyu Hu, Wenliang Zhang +10
We used transport and inelastic neutron scattering to study the optimally phosphorus-doped BaFe(AsP) superconductor ( K). In the normal state, we…
Global phase diagram of a spin-orbit-coupled Kondo lattice model on the honeycomb lattice
Xin Li, Rong Yu, Qimiao Si
Motivated by the growing interest in the novel quantum phases in materials with strong electron correlations and spin-orbit coupling, we study the interplay between the spin-orbit…
Multidimensional entropy landscape of quantum criticality
K. Grube, S. Zaum, O. Stockert +2
The Third Law of Thermodynamics states that the entropy of any system in equilibrium has to vanish at absolute zero temperature. At nonzero temperatures, on the other hand, matter…
Heavy-electron quantum criticality and single-particle spectroscopy
Stefan Kirchner, Silke Paschen, Qiuyun Chen +4
Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) have become indispensable tools in the study of correlated quantum materials. Both probe c…
Spectral Evidence for Emergent Order in BaNaFeAs
M. Yi, A. Frano, D. H. Lu +21
We report an angle-resolved photoemission spectroscopy study of the iron-based superconductor family, BaNaFeAs. This system harbors the recently discovered doub…
Singular charge fluctuations at a magnetic quantum critical point
L. Prochaska, X. Li, D. C. MacFarland +12
Strange metal behavior is ubiquitous to correlated materials ranging from cuprate superconductors to bilayer graphene. There is increasing recognition that it arises from physics b…
