Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly...

The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong...

This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner...

Recently, it has been reported that CeFeAsO belongs to orthorhombic structure where both Fe and Ce moments order antiferromagnetically around 140K and 4K, respectively, whereas...

Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most...

Recently the 5d transition metal oxide Sr2IrO4 has attracted much attention due to its close analogy with high-Tc cuprates. A hidden broken symmetry phase, which is similar to...

The extreme quantum nature of muons and muonium in condensed matter is the result of having a mass that is nine times lighter than that of a hydrogen atom. While this quantum...

Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest, as reduced dimensionality supports strong quantum fluctuations which can result...

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed...

We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the...

The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin...

The combination of strong magnetic frustration and low spin found in the S=1/2 quantum antiferromagnet is believed to lead to non-classical magnetic behaviour, and in particular...

Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with...

The work will aim to use the unique property of muons, as sensitive probes of their local magnetic environment, to investigate the source of the electronic magnetism observed in...

Nitrous oxide, N2O, is an inhalant anaesthetic with a long history of use dating back to 1844. It is most commonly used as a light sedative in dentistry, or in child birth and...

Superconductivity was recently discovered in alpha-phase FeSex with a Tc of 8 K. Selenium can be replaced with Tellurium (FeSe1-xTex) and this results in an increase in Tc to 15...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple...

Understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. All extant attempts to do this depend on the reaction of...

Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which...
