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... -
Identifying fractionalized magnetic excitations in the triangular spin-liquid...
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... -
Temperature dependence of spin dynamics near quantum criticality in an Ising ...
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... -
Fractionalized excitations in the zigzag pseudospin-1/2 quantum chain compoun...
One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may... -
Field Induced Magnetic Phase Transition close to Ferromagnetic QCP's
This proposal addresses the formation of a metamagnetic phase transition in PrPtAl. PrPtAl exhibits induced moment magnetism where singlet-mixing is stabilised by inter-site... -

Magnetic excitations in Strontium Erbium Oxide
In SrEr2O4 the magnetic Er ions are linked through a network of triangles and hexagons, where geometrical frustration can arise, provided that some exchange interactions are... -
Probing the random singlet state in antiferromagnetic Heisenberg spin chain c...
Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and... -
Inelastic neutron scattering study of the field dependent anisotropy of the s...
The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied... -
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... -
