Improved cMPS for Boson Mixtures
Analysis
This paper presents an improved optimization scheme for continuous matrix product states (cMPS) to simulate bosonic quantum mixtures. This is significant because cMPS is a powerful tool for studying continuous quantum systems, but optimizing it, especially for multi-component systems, is difficult. The authors' improved method allows for simulations with larger bond dimensions, leading to more accurate results. The benchmarking on the two-component Lieb-Liniger model validates the approach and opens doors for further research on quantum mixtures.
Key Takeaways
- •Improved optimization scheme for multi-component cMPS.
- •Enables simulations of bosonic quantum mixtures with larger bond dimensions.
- •Validated on the two-component Lieb-Liniger model.
- •Paves the way for further numerical studies of quantum mixture systems.
