Quantum critical dynamics in the presence of disorder
Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable... -
Copy of: Field driven quantum phase transition in a Kitaev honeycomb magnet
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... -
Magnetic excitation of Ca2RuO4 in pressure induced ferromagnetic phase
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... -
Anomalous lattice dynamics of the elemental superconductor niobium
Phonon lifetimes in BCS superconductors provide information on the details of the electron-phonon coupling mechanism. In 2008 high-resolution neutron inelastic scattering... -
Spin excitations in CeCoSi under hydrostatic pressure
The meta-orbital transition is a new theoretical concept to explain the nature of quantum criticality in heavy-fermion systems. Such a transition can occur e.g. as function of... -
Viscosity modifiers for CO2
There is a well-documented track record of research into water-in-CO2 (w/c) microemulsions. Using newly discovered CO2 compatible surfactants, the next step is to explore... -
Magnetic Spectrum of a New Spin Liquid with Heisenberg-Kitaev Interactions
We propose to continue our investigation of the magnetic excitation spectrum of the potential Kitaev spin liquid compound Li2RhO3. Moderate spin orbit coupling in the Rh4+ ion... -

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+).... -
Magnetic Excitation Spectrum of the Fe19 High Spin Molecular Nanomagnet
Our recent WISH study of the low temperature longe range ordered magnetic structure of the Fe19 single molecule magnetic system with S=35/2 produced an easy spin axis that is at... -
Magnetic field controlled quantum criticality in La2-xSrxCuO4
The application of a magnetic field offers a unique way to control a quantum critical point in some systems. For underdoped high temperature cuprate superconductors (HTS),... -
Tuning confinement potential of spinons in an Ising chain using magnetic fields
The Ising chain realises the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two kinks (spinons) that can separate away at no energy cost,... -
Phonon scattering and the thermal conductivity of zinc oxide
Understanding the thermal conductivity of zinc oxide is of central importance in assessing its potential for a wide variety of applications in optoelectronics, power electronics... -
Magnetic excitations in multiferroic hybrid perovskites
The novel electric, magnetic and multiferroic properties of the metal formate perovskites have resulted in substantial scientific attention over the past fifteen years. Their... -
Transverse field evolution of magnetic excitation spectrum in Nb1-yFe2+y
Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...
