Earth-size plasma facula oscillating at the surface of the Sun

Solar magnetic element of the Earth’s size oscillates with a few hours period and increasing amplitude, manifesting the vortex shedding effect in the magnetic flux emergence from the solar interior.

Colossal terahertz magnetoresistance

Recently, the Warwick Ultrafast Photonics group and collaborators have shown for the first time that colossal magnetoresistance can be found at terahertz frequencies. Studying electron dynamics in new electronic materials is important in the drive to create new devices for future data processing and communications schemes.

Researchfish submission deadline

FINAL REMINDER: we all, staff and RCUK-funded PhD students (normally in their third year of study), have until Thursday, March 16th, 2017 (inclusive) to complete our “researchfish” submissions. Please make sure that you have indeed “submitted”. Your reward should be an email similar to the one I received below. So, if in doubt whether you have indeed been successful in finding the “submit” button on researchfish, you can also search for “successfully submitted the award” among your received emails (please make sure you search the 2017 one, not last years).

Broken rotational symmetry on the Fermi surface of YBCO

Understanding the electronic proerties of the cuprate superconductors is key to figuring out the reason for their high transition temperatures. Tricky measurements in very high magnetic fields have recently shown that the Fermi surface of an underdoped high-temperature superconductor breaks fourfold rotational symmetry.
