Mott Intermittency at the Metal-Insulator Boundary
Yuxin Wang, Vladimir DobrosavljeviÄ, Jan JaroszyÅski +5
The resistivity maximum at a temperature is a recurring feature of bandwidth-tuned Mott systems, yet its meaning remains controversial: is it a coherence-incoh…
Quasiparticle to local moment crossover in bad metals
A. Chen, F. B. Kugler, P. Doležal +4
Non-Fermi-liquid charge transport in the vicinity of electronic instabilities has been intensely studied for decades. Deviations from in bad and strange met…
Universal relation between residual resistivity and A coefficient in correlated metals
Anna Yu. Efimova, Yohei Saito, Atsushi Kawamoto +3
The effects of strong electronic correlations and disorder are crucial for emergent phenomena such as unconventional superconductivity, metal-insulator transitions, and quantum cri…
Failed superconductivity in a Mott spin liquid material
Yuxin Wang, Vladimir DobrosavljeviÄ, Eun Sang Choi +5
A central challenge for understanding unconventional superconductivity in most strongly correlated electronic materials is their complicated band structure and presence of competin…
Pressure-induced topological changes in Fermi surface of two-dimensional molecular conductor
T. Kobayashi, K. Yoshimi, H. Ma +5
We demonstrated X-ray structural analysis of the pressure-induced superconductor, $β'$-ETICl under extremely high-pressure conditions, where ET denotes bis(ethylenedithio)…
Gapped magnetic ground state in the spin-liquid candidate -(BEDT-TTF)Ag(CN) suggested by magnetic spectroscopy
Sudip Pal, Björn Miksch, Hans-Albrecht Krug von Nidda +10
The nature of the magnetic ground state of highly frustrated systems remained puzzling to this day. Here, we have performed multifrequency electron spin resonance (ESR) measurement…
