The recent discovery of skyrmions and skyrmion lattices in materials with no inversion symmetry and their corresponding potential applications of Skyrmions in magnetic...

Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...

We propose to investigate the resonance peak in superconducting CeCoIn5 as a function of applied field. Preliminary low resolution cold triple-axis data has been suggestive that...

Motivated by the observation of incommensure magnetic order in Ba(Fe1-xCox)2As2, we have recently grown BaFe2-xNixAs2 crystals with systematic electron doping level especially...

The heavy fermion system CeCu6-xAux is arguably the most important (and studied) heavy fermion series which exhibits a quantum critical point. In recent years several new...

A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+)....

Evidence of long-range order has been observed in the diffuse neutron scattering data for a single crystal of HoTbTi2O7.A spin ice like pattern and pinch points coexist with the...

The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on...

We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well...

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...

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

Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states....

We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates...

Neutron experiment is carried out on relaxor magnet LuFeCoO4 to study the coupling between the slow dynamics of the dielectric and magnetic properties. At 190 K, the nuclear and...

Yb2Pt2Pb is a first-in-class system where spin ladders are coupled to quasiparticles, made massive by strong quantum mechanical fluctuations. The classical Yb moments are...
