simulated QPI image

That’s calcQPI, our code to calculate quasiparticle interference images, published. We find it indispensable to decipher our measurements! Find a survey of its features at www.arxiv.org/abs/2507.22137, the code is on GitHub at github.com/gpwahl/calcq....

Quantum materials making a stretch: giant magnetoelasticity driven by exchange interactions in Sr₄Ru₃O₁₀. Read in www.nature.com/articles/s41... how Carolina established control of the surface magnetization and probed it through Van Hove singularities. #evertoexcel @uniofstandrews.bsky.social
