Is disorder a friend or a foe to melting of Wigner-Mott insulators?
Mohammed Hammam, Cyprian Lewandowski, Vladimir Dobrosavljevic +1
Wigner crystals are extremely fragile, which is shown to result from very strong geometric frustration germane to long-range Coulomb interactions. Physically, this is manifested by…
Mechanism of charge transfer and electrostatic field fluctuations in high entropy metallic alloys
Wai-Ga D. Ho, Wasim Raja Mondal, Hanna Terletska +5
High entropy alloys present a new class of disordered metals which hold promising prospects for the next generation of materials and technology. However, much of the basic physics…
Universal scaling near band-tuned metal-insulator phase transitions
Simone Fratini, Sergio Ciuchi, Vladimir Dobrosavljevic +1
We present a theory for band-tuned metal-insulator transitions based on the Kubo formalism. Such a transition exhibits scaling of the resistivity curves, in the regime where …
Phase coexistence at the first-order Mott-transition revealed by pressure-dependent dielectric spectroscopy of -(BEDT-TTF)Cu(CN)
R. Rösslhuber, A. Pustogow, E. Uykur +7
The dimer Mott insulator -(BEDT-TTF)Cu(CN) can be tuned into a metallic and superconducting state upon applying pressure of 1.5 kbar and more. We have performed diel…
Low-Temperature Dielectric Anomalies at the Mott Insulator-Metal Transition
A. Pustogow, R. Rösslhuber, Y. Tan +10
The correlation-driven Mott transition is commonly characterized by a drop in resistivity across the insulator-metal phase boundary; yet, the complex permittivity provides a deeper…
Critical behavior at Mott-Anderson transition: a TMT-DMFT perspective
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
We present a detailed analysis of the critical behavior close to the Mott-Anderson transition. Our findings are based on a combination of numerical and analytical results obtained…
