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... -
Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
Low energy magnetic excitations on a new triangular-lattice antiferromagnet
Given the controversy about the magnetic ground state of the recently well studied triangular-lattice antiferromagnet (TLA) YbMgGaO4 due to Mg2+/Ga3+ disorder, we have... -
Field-driven closure of the Haldane gap in an ideal coordination polymer spin...
Chains comprising integer spin magnetic moments exhibit the celebrated non-magnetic Haldane phase, which is very different relative to the half-integer spin equivalent. We have... -

Magnetic excitations in a rare earth Kitaev material
Among the intense research on quantum spin liquid states, the Kitaev model has attracted great attention. Compounds consist of honeycomb layers with strong spin-orbit coupling,... -
Characterising the Holmium contribution to excitations in Holmium Iron Garnet
Rare-earth Iron garnets (R3Fe5O12) have been in the focus of active research for the last five decades due to properties such as magnetostriction, magneto-optical effects, as... -
Continuation of "Magnetic excitations in the quantum spin ice Yb2Ti2O7"
We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...
