Quantum and thermal critical scaling in XY-dipolar antiferromagnet LiErF4
We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition... -
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... -
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... -
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... -
Magnetic structure below the metal-insulator transition of Pb2CaOsO6
This proposal is part of a project in which we explore the unusual physics of 5d transition metal oxides. Using a special high pressure technique, we have synthesised first... -
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...
