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).
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).
DCA have installed a dual-chamber MBE system for the growth of designer oxide heterostructures at the School of Physics and Astronomy of the University of St Andrews. See below for a video of the assembly.
The MBE system will be coupled to existing state-of-the-art spectroscopic probes including low-temperature scanning tunneling microscopy and spectroscopy and angle-resolved photoemission. This EPSRC-funded strategic equipment (EP/M023958/1) will operate as a shared facility, which we aim to establish as a leading centre for the supply of custom oxide thin films within the UK.
Ana Maldonado, former TOPNES PDRA at the University of St Andrews, attended the Lindau Meeting of Nobel Laureates. The Nobel Laureate Meeting is an opportunity for early career researchers to meet excellent scientists from Nobel Laureates to undergraduate students.
