A neutron diffraction study of macroscopically entangled proton states in the high temperature phase of the KHCO3 crystal at 340 K
François Fillaux, Alain Cousson, Matthias J. Gutmann
We utilize single-crystal neutron diffraction to study the structure of potassium hydrogen carbonate (KHCO) and macroscopic quantum entanglement above the phase transiti…
Incommensurate magnetic ground state revealed by RXS in the frustrated spin system Ca3Co2O6
S. Agrestini, C. Mazzoli, A. Bombardi +1
We have performed a resonant x-ray scattering study at the Co pre-K edge on a single crystal of Ca3Co2O6. The measurements reveal an abrupt transition to a magnetically ordered sta…
Pinch Points and Kasteleyn Transitions: How Spin Ice Changes its Entropy
T. Fennell, S. T. Bramwell, D. F. McMorrow +1
Complex disordered states - from liquids and glasses to exotic quantum matter - are ubiquitous in nature. Their key properties include finite entropy, power-law correlations and em…
Quantitative determination of the Hubbard model phase diagram from optical lattice experiments by two-parameter scaling
Vivaldo L. Campo, Klaus Capelle, Jorge Quintanilla +1
We propose an experiment to obtain the phase diagram of the fermionic Hubbard model, for any dimensionality, using cold atoms in optical lattices. It is based on measuring the tota…
Absence of low temperature anomaly in the Debye-Waller factor of solid He-4
E. Blackburn, J. M. Goodkind, S. K. Sinha +6
The mean square atomic displacement in hcp-phase solid He-4 has been measured in crystals with a molar volume of 21.3 cm^3. It is temperature independent from 1 K to 140 mK, with n…
