Pauli spin susceptibility of a strongly correlated two-dimensional electron liquid

TL;DR

This paper reports that the Pauli spin susceptibility in a strongly correlated two-dimensional electron system in silicon increases sharply at low densities, indicating a possible phase transition.

Contribution

It provides experimental evidence of a critical growth in spin susceptibility, suggesting a phase transition in strongly correlated 2D electron liquids.

Findings

Spin susceptibility grows critically at low electron densities

Evidence of a phase transition in 2D electron systems

Behavior characteristic of strong electron correlations

Abstract

Thermodynamic measurements reveal that the Pauli spin susceptibility of strongly correlated two-dimensional electrons in silicon grows critically at low electron densities - behavior that is characteristic of the existence of a phase transition.
