Unveiling phonons in a prototype molecular quantum bit
The two main pillars of the current research in molecular magnetism are the possibilities of exploiting molecules as classical bits in high-density magnetic memories or as... -
Probing possible Dirac magnons in collinear antiferromagnets
Topological state of matter remains one of the central topics in condensed matter physics since decades ago. Take graphene as an example, the electron bands are linear and... -
Spin excitations in the first magnetic Weyl semimetal Co3Sn2S2
In contrast to the extensively verified Weyl semimetals with broken inversion symmetry, magnetic Weyl semimetals, which break time reversal symmetry, were only theoretically... -

Magnetic excitation spectrum near incipient SDW order in Nb1-xFe2+x
Our previous neutron diffraction on C14 Laves phase compounds Nb1-xFe2+x revealed thata spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical... -
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... -
Evolution of spin wave excitations of Mn3Sn in different magnetic ordered phases
Mn3Sn has very complex magnetic ordered phase, a clear magnetic phase transition happens at T=~280K accompanied by the vanishing of AHE.For our Mn3Sn crystal grown by flux... -
Single crystal measurement of the magnetic fluctuations in triclinic Cu3Nb2O8:
Cu3Nb2O8 is a helicoidal magnet which is also multiferroic and displays coupling between structural and magnetic chirality. In this proposal we propose to measure the magnetic... -
Investigation of a Potential realization of the Nersesyan-Tsvelik Model in (N...
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... -
Paramagnons in the chiral superconductor Sr2RuO4
Sr2RuO4 is a 2-D layered perovskite oxide metal which becomes superconducting below 1.5K. There is strong experimental evidence that the superconducting wavefunction is... -
Magnetic excitations in a candidate magnetic XY analogue of graphene
This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is... -
Continuation: Magnetic Excitations in doped Ca3Ru2O7 - Investigating the role...
Ca3Ru2O7 plays host to a complex interplay between equivalent spin-orbit coupling (SOC) and electron correlation energies that foster exotic physics and an extreme sensitivity...
