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.
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).
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.
The LHCb collaboration has just published in Phys. Rev. Lett. the first observation of a class of rare decays of a baryon containing the b quark. Studies of particles containing the b quark are of great interest as they provide opportunities to investigate asymmetries between matter and antimatter. Current and previous experiments have made detailed investigations into b mesons, but there is much less information available concerning b baryons. Observation of this new class of decay modes shows that it will in future be possible to make detailed studies of matter-antimatter asymmetries also with baryons, which may help to address one of the big mysteries in science today -- why a small amount of matter, that makes up our observable Universe today, survived from the symmetric conditions that existed shortly after the Big Bang.
Heterostructures combining multiple 2D materials are key to exploiting the promise of these novel materials in technological devices. New work involving investigators from the Department of Physics (Hine & Wilson) has investigated the unusual electronic structure effects at the interfaces formed when different transition metal dichalcogenide (TMDC) materials such as MoSe2 and WSe2 are combined.
