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

New preprint from CDQM at arxiv.org/abs/2505.07942: a study by quasi-particle interference and ARPES of the electronic structure of monolayer CrTe₂. Some of the first results from Olivia's STM4. Great collaboration with Naina, Akhil and King group.
