Search for the Nondimerized Quantum Nematic Phase in the Spin-1 Chain

TL;DR

This study numerically investigates the existence of a nondimerized quantum nematic phase in a spin-1 chain and finds evidence against it, suggesting a direct transition from ferromagnetic to dimerized phases.

Contribution

The paper provides the first numerical analysis challenging the proposed nondimerized quantum nematic phase in the spin-1 chain.

Findings

No evidence for the nondimerized quantum nematic phase

Direct transition from ferromagnetic to dimerized phase observed

Results contradict previous theoretical proposals

Abstract

Chubukov's proposal concerning the possibility of a nondimerized quantum nematic phase in the ground-state phase diagram of the bilinear-biquadratic spin-1 chain is studied numerically. Our results do not support the existence of this phase, but they rather indicate a direct transition from the ferromagnetic into the dimerized phase.
