Detuning Effects on Anomalous Chiral Spin Liquid
Analysis
This paper investigates the stability of an anomalous chiral spin liquid (CSL) in a periodically driven quantum spin-1/2 system on a square lattice. It explores the effects of frequency detuning, the deviation from the ideal driving frequency, on the CSL's properties. The study uses numerical methods to analyze the Floquet quasi-energy spectrum and identify different regimes as the detuning increases, revealing insights into the transition between different phases and the potential for a long-lived prethermal anomalous CSL. The work is significant for understanding the robustness and behavior of exotic quantum phases under realistic experimental conditions.
Key Takeaways
- •Investigates the stability of anomalous chiral spin liquids under frequency detuning.
- •Identifies three regimes based on the Floquet quasi-energy spectrum.
- •Suggests that the anomalous CSL is not continuously connected to the high-frequency CSL.
- •Discusses the potential for a long-lived prethermal anomalous CSL.
“The analysis of all the data suggests that the anomalous CSL is not continuously connected to the high-frequency CSL.”
