Electric field fluctuations in the two-dimensional Coulomb fluid
Callum Gray, Steven T. Bramwell, Peter C. W. Holdsworth
The structure factor for electric field correlations in the two dimensional Coulomb fluid is simulated and compared to theories of the dielectric function. Singular changes in the…
Screening and the Pinch Point Paradox in Spin Ice
Mikael Twengström, Patrik Henelius, Steven T. Bramwell
A pinch point singularity in the structure factor characterizes an important class of condensed matter that is a counterpoint to the paradigm of broken symmetry. This class include…
Ammonium Fluoride as a Hydrogen-disordering Agent for Ice
Christoph G. Salzmann, Zainab Sharif, Craig L. Bull +3
The removal of residual hydrogen disorder from various phases of ice with acid or base dopants at low temperatures has been a focus of intense research for many decades. As an anti…
Nuclear spin assisted quantum tunnelling of magnetic monopoles in spin ice
C. Paulsen, S. R. Giblin, E. Lhotel +4
Extensive work on single molecule magnets has identified a fundamental mode of relaxation arising from the nuclear-spin assisted quantum tunnelling of nearly independent and quasi-…
