The single band Hubbard model is considerably the simplest effective model that includes both the delocalizing/hopping energy and the on-site interaction for describing strongly...

It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and...

There is considerable interest in understanding the magnetoelectric effect with the aim of developing technological applications. Until recently this has been limited to...

Spin dynamics in multi-q noncoplanar ordered structures (e.g. skyrmion lattices) is an active topic of research. The cubic perovskite SrFeO3 has a variety of multiple-q magnetic...

Pr2Hf2O7 is a potential quantum spin ice compound. Compared to the classical spin ice ions Ho3+ and Dy3+, Pr3+ has weaker Ising anisotropy and significant XY terms leading to...

Ethanol plays an important role in the human metabolism. It is in particular known to act as a drug enhancer by increasing trans-membrane permeability, and as an anesthetic....

Our recent inelastic neutron scattering (INS) study using MARI clearly reveals the presence of a sharp inelastic excitation near 8 meV and 11 meV in CeT2Al10 (T=Ru and Os)...

We propose to study the low-energy spin fluctuations in ferromagnetic metal CeAgSb2. The ordered moment is oriented away from the direction favored by the lattice. Recent...

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known...

This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is...

It is well known that water is the medium in which the overwhelming majority of biological processes take place. In cell membranes water molecules are thought to be essential to...

Dynamics of multicomponent mixtures such as polymer blends are typically studied with QENS and deuterium labelling. Difficulties arise in the data analysis if the coherent...

Thermoelectricity enables the conversion of waste heat into useful power, and it is becoming increasingly important for power recovery applications at high temperature, where...

This proposal is about understanding the atomic-scale structure of complex oxides that contain water or protons and that are used as electrocatalyts for water splitting. Such...

The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on...

We request 2 days on MAPS (or 3 days on MARI) to determine the extent of solvent segregation in a liquid-liquid phase-separated metal-amine: The Li-NH3-MeNH2 system. Recently we...

Na2Ti2Sb2O has a CDW transition around 120 K . It has a tetragonal structure with alternate layers of Ti2Sb2O2- and Na+ double layer. Interestingly, the Ba1-xNaxTi2Sb2O system...

We propose to continue our investigation on LET of the Shastry-Sutherland compound SrCu2(BO3)2. The first part of the experiment aims to establish the Q-dependence, which will...

Spin fluctuations of materials close to a quantum critical point (QCP) exhibit anomalous behaviors. Sr3Ru2O7 has been shown to exhibit field-induced spin density wave (SDW)...

This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is...
