Only five days left until abstract submission deadline on 15 April (don't bet on it being extended!) - submit now your abstracts for minicolloquia 02 and 06 at the CMD32 (oepg-cmd-jointmeeting2026.uni-graz.at/en/), with an exciting programme of invited speakers.
Looking forward to a week of discussions and talks on physics at the DPG spring meeting #DPGDD26. See wahl.wp.st-andrews.ac.uk where and when to meet us and for a list of our contributions.
Meet us at the DPG spring meeting in Dresden

Interested in pursuing an EngD at the boundary between industry and University to explore new technologies for closed loop scanning with ultra-high resolution? Apply for our project in close collaboration with Razorbill Instruments at cdtphotonics.hw.ac.uk/project/deve.... Deadline 31st March.
Explorers wanted!

Looking for a PhD position combining theory and realistic modelling? We are looking for physics geeks with a hunch for numerical modelling to combine many body methods with simulations of quasiparticle interference, and who don't mind being a bit delocalised. www.st-andrews.ac.uk/study/fees-a...

Superconducting order parameter of UPt₃

What is the superconducting order parameter of UPt₃? Read our new preprint at arxiv.org/abs/2512.15845 to find how we use Andreev bound states to probe the symmetry of the superconducting order parameter.
Congratulations!

New preprint showing how long-wavelength moiré potentials and flat electronic bands can be generated from the interplay of a large lattice mismatch and an additional periodic modulation from a charge-density wave; with @wahlgroup.bsky.social & @maxivlaboratory.bsky.social. arxiv.org/abs/2511.05648
This is really scary - I always thought physics was safe. It would be huge loss to see physics departments close across the country.

Welcome to Ferran Aliagas Puigdomènech, who joins us from Universiteit van Amsterdam as a new PhD student in the group, working jointly with us and @wahlgroup.bsky.social
Many congratulations to Dan on successfully defending his PhD thesis: using LEED-IV to track minute structural distortions at ruthenate surfaces, and understanding their implications on electronic structure. Dan worked jointly with us, @wahlgroup.bsky.social and @diamondlightsource.bsky.social
Looking for highly motivated individuals who are keen to work on superconductivity in thin films of lanthanum nickelates. The project encompasses thin film growth by MBE, ARPES and STM. For the full advert, see www.vacancies.st-andrews.ac.uk/Vacancies/W/....

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
