Our paper on imaging and manipulating magnetic order of FeTe in vector magnetic fields has appeared in Science Advances, see https://goo.gl/8f2v9c. It shows how we can use spin-polarized STM not only to investigate surface magnetic order, but also to manipulate it.
Other talks by the group include talks on Quasiparticle Interference on minerals (by Carolina De Almeida Marques, talk A33.3 (Monday 8.24am) and on a strain-stabilized charge density wave in LiFeAs by Chi-Ming Yim, talk A10.4 (Monday 9.00am).
We will host the CMQM (Condensed Matter and Quantum Materials) meeting 2019 at the School of Physics and Astronomy, organized by the IOP. Through the CMQM conference we wish to provide a forum for the wider UK Condensed Matter Physics community to meet for discussions and to present their research across the specialised disciplines. The conference is supported by a wide range of relevant Institute of Physics groups and we envision it to be the first of an annual series, which we hope will rapidly become established as a platform for the community to come together in the spirit of the former CMMP meetings.
The meeting will take place 3-5 July 2019 in St Andrews, featuring plenary talks by Jacqueline Bloch, Andre Geim, Laura Heyderman, Steve Simon, and Julie Staunton, invited talks in specialized sessions and a poster session.
Our recent paper on the Discovery of a strain-stabilized smectic electronic order in LiFeAs is an Editors’ highlight in Nature Communications. Our work combines atomic-scale imaging by low temperature scanning tunneling microscopy with uniaxial strain. Straining the iron-based superconductor LiFeAs reveals the emergence of a new modulated phase, representative of a smectic electronic order. Tunneling spectra of the superconducting gap in this phase show a substantially modified superconducting order parameter.
Our results highlight the importance of electron-lattice coupling in the iron-based superconductor LiFeAs.
On Thursday, 8th of December, the Minister for Further Education, Higher Education and Science, Shirley-Anne Somerville, and the Principal of the University of St Andrews, Professor Sally Mapstone, opened a new center for Designer Quantum Materials. At the core of this facility is a reactive-oxide molecular beam epitaxy system, funded by the Engineering and Physics Sciences Research Council (EPSRC, EP/M023958/1).
Dr Peter Wahl with Minister for Further Education, Higher Education and Science Shirley-Anne Somerville Principal Prof Sally Mapstone Dr Philip King and head of School Prof Graham Turnbull The Minister for Further Education, Higher Education and Science Shirley-Anne Somerville today (8 December 2016) officially opened a state-of-the-art centre for Designer Quantum Materials at the University of St Andrews. The centre, the first of its kind in the UK, is aimed at the creation of new materials which do not exist in nature. Almost like building LEGO structures with single atom building blocks, the Designer Quantum Materials lab allows the composition of a material to be changed between each layer, effectively making entirely new “supermaterials” – combinations and structures which would be impossible to create by any other means. At the heart of the facility is a molecular-beam epitaxy (MBE) system which can custom engineer materials which can be used in a host of applications from super-efficient energy distribution to high performance computing and sensing.
We are participating in the DAAD RISE programme which offers undergraduate students from Germany an opportunity to go abroad to work on a small research project. Have a look at the web pages of DAAD for more information (in german).
