Congratulations to Olivia to her viva and a great PhD thesis on “Scanning Tunnelling Microscopy of Magnetic van der Waals Materials”, and many thanks to Philip Moriarty and Renald Schaub for examining the thesis!
How good are different surfaces at deactivating SARS-CoV-2 viruses. Copper beats them almost all – except cuprous oxide (Cu2O)! Why is that? Read more in our new paper in Applied and Environmental Microbiology ahead of print. Great interdisciplinary collaboration across CDQM and with Cathy Adamson from the School of Biology and her team.
This image shows how ChatGPT ‘thinks’ our research looks like, in response to a prompt to produce an image representing our research as described here. If you want to find out what it looks like in reality come to Peter’s inaugural lecture on Wednesday, 22 November, 5.15pm, School 3, St Salvator’s Quad.

How can one control electronic structure just with magnetic fields? In our new paper, we track how the electronic structure in Sr3Ru2O7 changes as a function of applied field direction, providing direct imaging of a field-controlled nematicity and how to control electronic structure with surprisingly modest magnetic fields. Also another good example of how the surface can differ subtly from what the bulk does …

Congratulations to Seohyun, Rebecca and Lewis to their graduation this week and great results in their final year projects! Looking forward to welcome and work with Rebecca and Seohyun as PhD students in the School from September, Rebecca in the group and Seohyun with Bernd Braunecker and Luke Rhodes.
Read in our new preprint by Masahiro and Izidor about how we can control nematicity in the surface layer of Sr3Ru2O7 by vector magnetic fields. Dependent on the direction of the applied field, we find checkerboard charge modulations, nematicity and stripe modulations which can all be explained from a minimal tight-binding model that accounts for magnetism and spin-orbit coupling. Key open question: can the same minimal model explain the behaviour in the polarized phase in the bulk?

Read in Carolina’s new preprint on the Van Hove singularity in Sr4Ru3O10 how we can use quasi-particle interference imaging to identify its symmetry, spin and orbital character. Our results hint at a new mechanism for a magnetic-field-driven Lifshitz transition.
