QM in the news

16 May 2024

Last summer's research trip to the Synergetic Extreme Condition User Facility (SECUF), Beijing, by QM members Zheyu Wu, Theo Weinberger & Alex Eaton has been featured in a recent Nature news article. The trio were the first international user group to be awarded measurement time on a new world-unique all-...

Metallic magnetocalorics findings published

26 April 2024

Thomas Gruner and colleagues in the QM group and at the MPI-CPfS in Dresden showed that YbNi2Sn retains high spin entropy down to very low temperatures, much less than 1K, despite being a good metal. On the face of it, this is unexpected, because electrons in metals form a degenerate Fermi gas, and so their entropy...

APS March Meeting 2024

18 March 2024

A number of QM group members recently travelled to the American Physical Society March Meeting in Minneapolis, Minnesota, along with over 11,000 other attendees. Talks by QM members spanned a range of topics from the electronic structure of Dirac nodal-line semimetals through to the high magnetic field phase landscape of...

QM Seminars Lent term

12 February 2024

The QM seminar series has picked up this term, with Clifford Hicks (Birmingham) giving a very interesting survey of recent developments in Sr 2 RuO 4 in January, followed last week by Tamaghna Hazra (KIT Karlsruhe), who talked about upper limits on T c imposed by phase fluctuations. Coming up: Alix McCollam (Cork) on 22...

UTe2 Fermi surface paper published in Nature Communications

5 January 2024

A collaboration led by Research Fellow Dr. Alex Eaton is making rapid progress with resolving the Fermi surface and carrier mass in the unconventional superconductor UTe2, providing key input to any comprehensive theoretical description. Results from a series of quantum oscillation measurements have now been published in...

Stephen Hodgson PhD

8 October 2023

Stephen Hodgson passed his PhD viva with minor corrections last week and was celebrated by a group outing on Friday - congratulations! We thank his examiners - external, Prof. Stefan Süllow (Brunswick/Germany) and Dr. Michael Sutherland (QM, Cavendish). Stephen brought high pressure heat capacity techniques to our group...

High pressure quantum oscillation measurements in a Mott metal, PNAS paper published

7 October 2023

Correlated electron materials display a zoo of ordered states such as multiple forms of magnetism and superconductivity, but the metallic 'normal' state from which these arise is itself in many cases only incompletely understood. One of the most fundamental examples of such a correlated normal state occurs as a Mott...

Three UTe2-papers in quick succession

9 September 2023

Junior Research Fellow Dr. Alex Eaton with PhD students Theo Weinberger and Zheyu Wu have made rapid progress in their investigation of the new unconventional superconductor UTe 2 : in three papers submitted in quick succession to high-profile journals, they present a convincing model for the Fermi surface geometry in UTe...

A new unconventional superconductor, CeSb2; PRL publication

14 August 2023

CeSb 2 has the immense advantage that clean single crystals are fairly straightforward to grow. It is well-known and - at ambient pressure - has been studied in great detail. However, we found that it undergoes a Dr. Jekyll - Mr. Hyde structural transformation under moderate applied pressure, and in its high pressure...

Alex Hickey PhD

20 April 2023

Congratulations to Alex Hickey for passing his PhD viva on 31 March 2023. His thesis, intriguingly titled "Big data, bigger magnets, and tiny high-temperature superconducting cuprates", was examined by Prof. Louis Taillefer (Sherbrooke/Canada) and Dr. Michael Sutherland (QM, Cavendish). All the best for your next career...
