Critical and quantum critical spins fluctuations in URhGe
Ferromagnetism in URhGe is continuously suppressed with a magnetic field leading to a Quantum Critical Point (QCP) at around 12 T engulfed by a pocket of superconductivity. The... -
Lattice dynamics in magnetoelectric HoMnO3
The manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large... -
S=1 triplet character of the resonance peak in CeCoIn5
We propose to investigate the resonance peak in superconducting CeCoIn5 as a function of applied field. Preliminary low resolution cold triple-axis data has been suggestive that... -

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we plan to use... -
Magnetic Excitations on the Frustrated Triangular Lattice of UAu2
Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted.... -

The experimental identification of quantum spin liquids (QSL) in real materials has been one of the challenging and fundamental goals in condensed matter physics. The newly... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
Magnetic critical scattering in UGe2 under pressure
The proposal is to measure the low-energy spin dynamics of the ferromagnetic superconductor UGe2 at the pressure which maximizes superconducting transition temperature and at... -
Spinon Confinement and Longitudinal Interchain modes in Yb2Pt2Pb
The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with...
