Quick Summary

Chinese physicists have found that tipping points in physical systems can exhibit a topology similar to a doughnut’s hole, linking critical phenomena with topology for the first time. This discovery challenges traditional views that these two areas of physics are distinct and unrelated. The study was published in Nature on October 7 by researchers from Singaporean and Chinese institutions, with Cheng Zheyu and Zhang Xiuhai as co-first authors.

Story summary

Chinese physicists have discovered that tipping points, where physical systems rapidly shift states, can exhibit a smooth mathematical structure resembling a doughnut’s hole. This finding, published in the journal *Nature* on October 7 by researchers from Singaporean and Chinese institutions, challenges long-held beliefs that critical phenomena and topology must be studied separately. Cheng Zheyu and Zhang Xiuhai of Nanyang Technological University in Singapore are co-first authors of the study, which suggests a new way to bridge these two areas of physics research. This breakthrough could open up new pathways for fundamental science exploration.

🔮 The study by researchers at Singaporean and Chinese institutions was published in Nature on October 7, with Cheng Zheyu and Zhang Xiuhai, both affiliated with Nanyang Technological University in Singapore, as co-first authors. Cheng and his colleagues set out to investigate whether doughnut-like topological properties could exist at critical points – the thresholds at which physical systems change their behaviour.

For decades, mainstream physicists have mostly treated critical phenomena, which describe how physical systems change at critical points, and topology, which studies the properties of geometry, as separate areas of research. asserted
which → treat → research
The two cannot be transformed into each other by stretching or bending alone because they have a different number of holes, unless the surface is cut or glued. asserted
