Wigner-Mott quantum criticality: from 2D-MIT to 3He and Mott organics
Abstract
Experiments performed over the last twenty years have revealed striking similarities between several two-dimensional (2D) fermion systems, including diluted two-dimensional electron liquids in semiconductors, 3He monolayers, and layered organic charge-transfer salts. These experimental results, together with recent theoretical advances, provide compelling evidence that strong electronic correlations - Wigner-Mott physics - dominate the universal features of the corresponding metal-insulator transitions (MIT). Here we review the recent theoretical work exploring quantum criticality of Mott and Wigner-Mott transitions, and argue that most puzzling features of the experiments find natural and physically transparent interpretation based on this perspective.
