Neutron Larmor diffraction investigation of the rare earth pyrochlores TiO ( = Tb, Dy, Ho)
M Ruminy, F Groitl, T Keller +1
In this work we present a neutron Larmor diffraction study of the rare earth pyrochlores TiO, with = Tb, Dy, Ho. We measured the temperature dependence of the latt…
Time-dependent correlations in quantum magnets at finite temperature
B. Fauseweh, F. Groitl, T. Keller +4
In this article we investigate the time dependence of the gap mode of copper nitrate at various temperatures. We combine state-of-the-art theoretical calculations with high precisi…
Anomalous thermal decoherence in a quantum magnet measured with neutron spin-echo spectroscopy
Felix Groitl, Thomas Keller, Katharina Rolfs +2
The effect of temperature dependent asymmetric line broadening is investigated in Cu(NO)2.5DO, a model material for a 1-D bond alternating Heisenberg chain, using…
Luttinger-Liquid Behavior in the Alternating Spin-Chain System Copper Nitrate
B. Willenberg, H. Ryll, K. Kiefer +8
We determine the phase diagram of copper nitrate Cu(NO)2.5DO in the context of quantum phase transitions and novel states of matter. We establish this compound as…
