Interfacial Adsorbtion from Nematic Mixtures
The aim is to determine the amount of absorbtion of the one component of a mixture at the nemtic/air interface using neutron reflection. The host material in the mixture will be... -
Temperature driven spin incoherence and criticality in the Luttinger liquid p...
We propose an experiment on the low energy spectrometer LET to study temperature effects on the Luttinger liquid (LL) phase on the spin ladder geometry. The spin ladder material... -
Magnetic Excitation Spectrum of the Frustrated Antiferromagnet SrYb2O4
In SrYb2O4 the magnetic Yb3+ ions form sub-lattices of double chains running parallel to the crystallographic c-axis with frustrated first and second neighbour antiferromagnetic... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
High pressure polymorphism in ammonium bicarbonate, (ND4)DCO3
In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent... -
Quantum dynamics in a J_eff=1/2 isotropic triangular-lattice antiferromagnet
This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum antiferromagnets. A canonical model system is the spin-1/2 triangular... -
IINS study of the terminating protons in the basic structural units of graphi...
Carbon blacks can be graphitised to different degrees, whereas glassy (vitreous) carbons, which are used as electrode material, in electronics and construction, and as... -
Rattling modes in new thermoelectrics
NaxCoO2 has an exceptional combination of thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery and as... -
Dynamical Signatures of Quantum Spin Ice in Tb2Ti2O7
We propose the first neutron scattering experiment on the frustrated magnet Tb2Ti2O7 in the presence of a magnetic field along [111]. This will allow us to uncover signatures of...
