Linear behavior of the optical conductivity and incoherent charge transport in BaCoS2
D. Santos-Cottin, Y. Klein, Ph. Werner +5
Optical conductivity measurements on a BaCoS2 single crystal show an unusual linear behavior over a broad spectral range. In the paramagnetic phase above 300 K, the spectrum shows…
Hund's metals, explained
Luca de' Medici
A possible practical definition for a Hund's metal is given, as a metallic phase - arising consistently in realistic simulations and experiments in Fe-based superconductors and oth…
Thermodynamic signatures of the field-induced states of graphite
D. LeBoeuf, C. W. Rischau, G. Seyfarth +7
When a magnetic field confines the carriers of a Fermi sea to their lowest Landau level, electron-electron interactions are expected to play a significant role in determining the e…
Metallicity without quasi-particles in room-temperature strontium titanate
Xiao Lin, Carl Willem Rischau, Lisa Buchauer +3
Cooling oxygen-deficient strontium titanate to liquid-helium temperature leads to a decrease in its electrical resistivity by several orders of magnitude. The temperature dependenc…
