Universal Quantum-Critical Dynamics of a Two Dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
Uniaxial pressure effect in FeTe
Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering... -
Magnetic field controlled quantum criticality in La2-xSrxCuO4
The application of a magnetic field offers a unique way to control a quantum critical point in some systems. For underdoped high temperature cuprate superconductors (HTS),... -
Magnetic Excitations in the Shastry-Sutherland magnet; Neodymium Tetraboride
We are proposing to investigate the magnetic excitations of NdB4 in zero field using LET. NdB4 crystallises into tetragonal structure where the Nd ions forms layers which map to... -
Anomalous lattice dynamics of the elemental superconductor niobium
Phonon lifetimes in BCS superconductors provide information on the details of the electron-phonon coupling mechanism. In 2008 high-resolution neutron inelastic scattering... -

Dimensional Reduction and Frustration in the 2D Quantum Dimer Magnet BaCuSi2O6
For a decade field-tuned quantum criticality in the spin-dimer system BaCuSi2O6 has been of great interest due to an unconventional dimensional crossover at its quantum critical...
