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...

This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum magnets. A canonical model is the spin-1/2 triangular antiferromagnet...

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...

LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related...

We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition...

The electron-phonon interaction is a major factor influencing the competition between collective instabilities in correlated-electron materials, but its role in driving...

In a number of recent experiments on the pure CeB6 compound, we have revealed strong quasielastic inten-sity in the normal (paramagnetic) state with a rich momentum-space...

This proposal is concerned with the structural study of anionic and cationic surfactant mixture on a charged metal oxide surface using neutron reflectivity. Also to evaluate the...

The spin Seebeck effect (SSE) is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric generators. The...

We propose to study the magnetic fluctuations of the unconventional superconductor Sr2RuO4 in the superconducting state extending our previous experiments on a cold triple-axis...

Sr2RuO4 is an oxide metal which becomes superconducting at 1.5 K. In conventional superconductors, the electron (Cooper) pairs responsible for superconductivity have zero...

We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of...

Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the...

We propose to investigate the highly one-dimensional (1D) S=1/2 Heisenberg antiferromagnet (NO)[Cu(NO3)3] which is a potential realization of the Nersesyan-Tsvelik model. The...

Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure...

The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,...

Quantum critical points (QCPs) have attracted continuous scientific interest due to the emergent phenomena observed in their vicinity, including unconventional superconductivity...

Recent experiments on SANS2D have indicated that small colloidal particles can act as macroions that screen the charged interactions of larger particles. This can cause changes...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

The newly discovered AxFe2-ySe2 (A=K,Rb,Cs) compounds have attracted great interests because of their parent compounds are insulators instead of being metallic [2-6]....
