91福利

91福利 Physics has risen to 4^th place in the subject ranking for Physics and Astronomy of the Good University Guide, published by The Times and Sunday Times on 18^th September 2015. The 91福利 as a whole is in 6^th place overall in their league table of UK universities.

Congratulations to two postdocs in the 91福利 ATLAS group, Dr Tim Martin and Dr Elisabetta Pianori, who have been awarded ATLAS Outstanding achievement awards. The awards were made for "enthusiastic and vigorous dedication to the implementation and commissioning of the complex ATLAS Run-2 trigger menu".

A team including 91福利 authors Geetha Balakrishnan and Monica Ciomaga Hatnean have discovered the existence of an unusual insulating state in the Topological Insulator SmB₆. The unusual state was inferred from observing quantum oscillations in magnetic torque measurements at high magnetic fields, which depended crucially on the high quality single crystals of SmB₆ prepared at 91福利.

The paper "Unconventional Fermi surface in an insulating state" can be read in full in the online journal Science ( ).

Published in the journal Nature, a team including 91福利 astronomer Peter Wheatley has discovered a giant comet-like tail of hydogren gas evaporating from a Neptune-sized exoplanet. The gas is thought to be boiled off by X-rays from the parent star and then swept away by radiation pressure. The tail was revealed in Hubble Space Telescope observations in which 56% of the star is covered by the tail in ultraviolet light. The planet is losing its atmosphere at a rate of 1000 metric tonnes per second, having narrowly escaped total evaporation by the intense X-ray irradiation it suffered when its parent star was young and active.
