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…
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…
Valence-bond theory of highly disordered quantum antiferromagnets
S. Zhou, J. A. Hoyos, V. Dobrosavljevic +1
We present a large-N variational approach to describe the magnetism of insulating doped semiconductors based on a disorder-generalization of the resonating-valence-bond theory for…
Coulomb Correlations and the Wigner-Mott Transition
A. Camjayi, K. Haule, V. Dobrosavljevic +1
Strong correlation effects, such as a dramatic increase in the effective mass of the carriers of electricity, recently observed in the low density electron gas have provided specta…
