Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted....

Nd2Zr2O7 is a new candidate for quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field ground state...

The interaction of ionizing radiation such as X-rays with biological samples causes damage to the samples. Recent work from our group with various protein crystals, peptides and...

In recent years topologically complex materials have provoked questions about the basic models of magnetism. These materials have given rise to unusual phenomena, including...

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...

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...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model uniquely provides exactly...

The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with...

The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also...
