Open AccessSpin effect on the low-temperature resistivity maximum in a strongly interacting 2D electron system
The increase in the resistivity with decreasing temperature followed by a drop by more than one order of magnitude is observed on the metallic side near the zero-magnetic-field metal-insulator transition in a ...

Open AccessLow-temperature dielectric anomaly arising from electronic phase separation at the Mott insulator-metal transition
Coulomb repulsion among conduction electrons in solids hinders their motion and leads to a rise in resistivity. A regime of electronic phase separation is expected at the first-order phase transition between a...

Quantum spin liquids unveil the genuine Mott state
The localization of charge carriers by electronic repulsion was suggested by Mott in the 1930s to explain the insulating state observed in supposedly metallic NiO. The Mott metal–insulator transition has been ...

Two-stage magnetic-field-tuned superconductor–insulator transition in underdoped La2−xSrxCuO4
In the underdoped pseudogap regime of cuprate superconductors, the normal state is commonly probed by applying a magnetic field (H). However, the nature of the H-induced resistive state has been the subject of a ...

Coulomb correlations and the Wigner–Mott transition
Evidence for metal–insulator transitions in dilute 2D electron gases has sparked controversy and debate. A new model suggests such behaviour could arise from strong correlations driven by non-local Coulomb int...
