Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

In recent times, materials with low-lying phonon (for instance K2Os2O6 [1]) have attracted immense interest in an aim to discover high transition temperature TC superconductors....

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

Our recent µSR measurements on a polycrystalline sample of Ru7B3 has shown that this material is an excellent example of broken time reversal symmetry on entering the...

Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin...

One goal of our research into the nanoengineering of molecular magnets is a detailed understanding of the relationship between the structure and composition of a system and its...

k-ET_2Cu_2(CN)_3 provides an excellent experimental system for studying the 2D S=1/2 frustrated triangular lattice Heisenberg model. A spin-liquid state persists in this system...

In superconductors, the inversion symmetry of the crystallographic structure plays a central role in the formation of the Cooper pairs. When inversion symmetry is broken, there...

Quantum spin liquid (QSL) is an ordered spin state which has been destroyed by quantum fluctuations at low temperatures. Low energy excitations of spin liquids are charge...

We propose to investigate the effects of the electron- phonon interaction on the time reversal symmetry breaking phenomenon of non-cetrosymmetric superconductors. μSR is...

Quantum phase transitions (QPT's) are phase transitions that are driven by zero-temperature quantum fluctuations, and are accessed by varying a non-thermal control parameter....

The kappa structural phase of BEDT-TTF salts incorporating various anions X provides an extremely interesting series of layered-structure strongly-correlated materials, whose...

The search for unconventional superconductors has been a cornerstone of research in condensed matter physics for many years. Recently a key research interest has been...

Geometrically frustrated magnetic systems have been widely studied in the search for novel quantum states of matter. The fcc lattice Ba2YMoO6 has been shown to be a valence bond...

LiZn2Mo3O8 is a highly unusual geometrically frustrated material: the magnetic moments are associated not with single ions but with small transition-metal clusters. The spin is...

Pure Ho2Ti2O7 exhibits spin ice beahviour. Studies of doped spin ice, replacing Ho with non-magnetic Y, suggest that the spin ice state is present even when the amount of doping...

Quantum spin liquids (QSLs) are intriguing states of matter in which quantum fluctuations are sufficiently strong to destroy any long-range magnetic order. To date, one of the...

We propose to investigate the effects of the electron- phonon interaction on the time reversal symmetry breaking phenomenon of non-cetrosymmetric superconductors. μSR is...

Recently, Eckert and co-authors synthesised osmium based two superconductors, NbOsSi and TaOsSi, and found that these compounds exhibit superconductivity below a transition...

Rare-earth delafossites were recently proposed as promising candidates for the realization of an effective S = 1/2 quantum spin liquid on the triangular lattice [1, 2]. In...
