Tests of quantum coherence could demonstrate biological systems exploiting quantum phenomena. This paper discusses such tests and how the role the environment must be considered to witness coherence.
Report on ‘Extreme Nanowire, Phase Formation and Molecular Encapsulation in Atomically Thin Capillaries: Practice, Theory and Experiment’ Physics Day, 3rd July 2018
This Physics Day was essentially a workshop concerned with experimental electron microscopy and theoretical modelling of ‘Extreme Nanowires,’ the smallest nanowires that can be formed down to a single atom width, and also discrete molecules formed on a similar scale. The Physics Day included contributions from four Warwick speakers, including two PhD students, UK speakers Prof. Andrei Khlobystov, Dr. Thomas Chamberlain and Dr. Andrew Morris from the Universities of Nottingham, Leeds and Birmingham respectively, and also the distinguished International Speaker Prof. Kazu Suenaga from the AIST in Tsukuba, Japan. This event was also used as a preamble for the EMAG (Electron Microanalysis and Analysis Group) meeting which was taking place in Warwick during the same week (i.e. 6th-8th July).
Tim Gershon and Anton Poluektov have proposed a new method that may make it possible to observe a long-sought after type of particle called double beauty hadrons.
New research by a team led by Dr Farzana Meru has a way of finally telling whether newly forming planets are migrating within the disc of dust and gas that typically surrounds stars or whether they are simply staying put in the same orbit around the star.
Touching proteins with virtual bare hands: how to visualize protein-drug complexes and their dynamics in virtual reality
The ability to precisely visualize the atomic geometry of the interactions between a drug and its protein target in structural models is critical in predicting the correct modifications in previously identified inhibitors to create more effective next generation drugs. Here we present a freely available software pipeline for visualising protein structures through virtual reality (VR) on regular customer hardware, such as the HTC Vive and the Oculus Rift.
Dominic Branford and Animesh Datta, working in collaboration with Haixing Miao (University of Birmingham), have published a paper on the fundamental quantum limits of optomechanical sensors in Physical Review Letters (DOI: 10.1103/PhysRevLett.121.110505). Being able to measure very weak forces is central to many applications, such as the direct detection of gravitational waves and monitoring subterranean movement of magma in volancially-active areas. The strength of a force can be inferred through its effect of displacing a mass: the displacement can be sensed by illuminating it with a laser and observing the reflected light, a case of optomechanical sensing. In this work, Dominic, Haixing and Animesh study the best precision attainable by optomechanical sensors when multi-coloured light is used.
