Happy to share a work from my sabbatical at ETH Zurich. I found that the quantum metric serves as a signature of persistent spin helix states, which host long-lived spin textures. Preprint just out on the arXiv:

"What’s fascinating about biological problems is that they operate on multiple time scales," says Govardhan Reddy, Associate Professor in SSCU, IISc. His lab studies how riboswitches help bacteria survive.
