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...

We propose to study the magnetic excitation spectrum of Na2IrO3 with inelastic neutron scattering. Na2IrO3 is a promising candidate to realize Kitaev interaction. By mapping out...

The present scientific case concerns a glass-forming system with even less degrees of freedom, namely the occupational disorder of high-temperature phase (I, P21/c) of...

With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously...

The recent exciting observations in the magnetic excitation spectra of cobalt oxides that are isostructural to the prototypical high-temperature superconducting cuprates have...

Spin ice (SI) is a state of matter characterized by a residual (Pauling) entropy and unusual correlations. The huge interest in SI materials from the magnetism community stems...

Recently, a novel type of Bose-Einstein condensation (BEC) of spin-orbit excitons has been proposed in Mott insulator Ca2RuO4. In the recent INS study, we have observed...

One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These...

Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC...

The proposal requests time to obtain a full mapping of the low-energy acoustic phonons. We have measured an acoustic phonon anomaly associated with the structural transition and...

Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal...

The Mn3Ge compound have recently attracted giant attention due to discovery of large anomalous Hall effect. This effect is believed to originate in the non-collinear...

PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu2+ ions coupled by 3 interactions. The 1st neighbor interaction couples Cu2+ into isolated triangles, 2nd nearest...

We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial...
