Phase diagram and spin nematic phase transitions in biquadratic spin- 1 and spin-2 XY chains with single-ion anisotropies

Key Points

• The spin nematic phase is a new state of matter observed in both spin-1 and spin-2 XY chains.
• Significant transitions occur due to biquadratic spin interactions and single-ion anisotropies.
• Analysis focused on phase diagrams which detail how different variables influence spin arrangements.
• Findings suggest that these transitions could open avenues for new technologies in quantum computing.
