Quantum critical dynamics in the purely dipolar antiferromagnet LiErF4
LiErF4 is an example of an XY dipolar coupled antiferromagnet with planar anisotropy. As such it exhibits a quantum phase transition (QPT) in a small field of 4kOe, which is of... -
Low energy excitations in solid 4He
The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the... -
Quantum-Critical Dynamics of a 3-dimensional Antiferromagnet
We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of... -
Rattling modes in new thermoelectrics
NaxCoO2 has an exceptional combination of thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery and as... -
In-situ hydrogen decomposition studies of ammonia borane and the diammoniate ...
Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3... -
'Stabbing' or 'cut & thrust'? Texture analysis to distinguish usage of Bronze...
Defining when the practical use of Bronze Age swords changed from stabbing to cut-and-thrust weapons would have a huge impact on Bronze Age research. The change was accompanied...
