Topological insulators are exotic field of study because of presence of fully gapped bulk states and gap less surface states protected by Time Reversal Symmetry (TRS)....

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...

Previous work on the polymer RR-P3HT has found that the ALC resonance collapses at 100K to ~80% of the 300K ALC magnitude, this is much larger than the decrease seen for small...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

Skyrmions are topologically protected vortex-like spin textures, and have been attracting increasing attention due to their potential technological applications for spintronics....

Our susceptibility studies of the frustrated magnet Yb2Sn2O7 has revealed a spin glass transition of the Yb3+ magnetic lattice at T_g = 140 mK. To our knowledge, this...

The quantum spin liquid (QSL) is a long-standing attractive topic in condensed matter physics due to its tight relation to exotic properties such as high temperature...

Rare-earth based geometrically frustrated magnets represent a promising new platform for the search of enigmatic quantum spin liquids. Here, the entanglement of spin and orbital...

We wish to measure the ALCs of a series of polyacene molecules made of a different number of rings. We would like to identify the dependence of the electron spin relaxation rate...

The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to...

Spin liquids are phases of matter where, in spite of strong near neighbour magnetic interactions, long range magnetic ordering is prevented due to conflicting interactions....

Recently there have been many reports on how high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at...

CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been...

a-RuCl3 is a honeycomb lattice system which is thought to be close to a spin liquid state. The layers are weakly coupled and therefore the system is susceptible to stacking...

We will examine the impact of metal-halide hydrogen bond motifs and their ability to provide low-dimensional superexchange pathways. Specifically, we wish to investigate two new...

Here we propose a u+SR investigation on the solid solution Cax-1NaxCr2O4, a Q1D zigzag chain compound where Na+ ions are allocated in the hexagonal one-dimensional channels...

CeCu2Si2 was the first heavy fermion superconductor and unlike those previously discovered, which were well explained by BCS theory, CeCu2Si2 is an unconventional...

The implementation of safe high voltage Li-ion batteries, capable of powering demanding technologies such as electric vehicles, is precluded by the current use of organic...

In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive...
