Summary

Story summary

Scientists developed a novel algorithm to simulate thermal pure quantum states, implemented in the open-source Physica library.
The method delivers about a 100-fold speedup for the Hubbard model and expands the temperature range across various doping levels.
It improves efficiency and stability for reliable thermal properties.
The National Key Research and Development Program of China and the National Natural Science Foundation of China funded the work.
