Excitations of the Zeeman ladder in a transverse field in the Ising antiferro...
The excitations of an Ising antiferromagnetic chain have been studied in the past and are known to form either continuous spectrum or Zeeman ladders. Such a system can be... -
The anisotropy of the spin fluctuations in the electron nematic phase of Sr3R...
New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is... -
Detecting an entanglement transition in a quantum magnet
Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This... -
Magnetic excitation spectra in the field induced quantum phases of the quasi-...
We propose to investigate the magnetic excitation spectra in the three accessible magnetic ordered phases of the quasi-1D S-1/2 Ising-like antiferromagnet SrCo2V2O8 by single... -
Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
The phase diagram of the spin-density-wave metamagnet Sr3Ru2O7
Sr3Ru2O7 is an unusual layered oxide metamagnetic metal. It has been know for some time that the application of a large magnetic field (~8 T) perpendicular to the RuO2 planes... -

Metallic chains on a triangular lattice
Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at... -

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 apply for a... -
Cascading magnetization plateaus in monoclinic CoV2O6
The aim of this proposal is to understand the origin of the cascade of magnetisation plateaus in monoclinic CoV2O6. While 1/3 plateaus have been reported in the literature,... -
E/T scaling and quantum critical fluctuations in Sr3Ru2O7
Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature.... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
Electric field effects on the spin correlation length in multiferroic delafos...
In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1].... -
Neutron Diffraction study of Highly Frustrated SrEr2O4
We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked... -
Quantum Criticality in YFe2Al10
Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10... -
