Unstable Spin-Ice Order in the Stuffed Metallic Pyrochlore PrIrO
D. E. MacLaughlin, O. O. Bernal, Lei Shu +12
Specific heat, elastic neutron scattering, and muon spin rotation (SR) experiments have been carried out on a well-characterized sample of "stuffed" (Pr-rich) PrIr$_{2-x…
Entanglement structure of the Hubbard model in momentum space
G. Ehlers, J. Sólyom, Ö. Legeza +1
We study the properties of the ground states of the one- and two-dimensional Hubbard models at half filling and moderate doping using entanglement-based measures, which we calculat…
Order-disorder transitions in a sheared many body system
Jens C. Pfeifer, Tobias Bischoff, Georg Ehlers +1
Motivated by experiments on sheared suspensions that show a transition between ordered and disordered phases, we here study the long-time behavior of a sheared and overdamped 2-d s…
Nature of Partial Magnetic Order in the Frustrated Antiferromagnet Gd2Ti2O7
Joseph A. M. Paddison, Andrew B. Cairns, Dmitry D. Khalyavin +8
The frustrated pyrochlore antiferromagnet GdTiO has an unusual partially-ordered magnetic structure at the lowest measurable temperatures. This structure is curre…
Overcoming High Energy Backgrounds at Pulsed Spallation Sources
Nataliia Cherkashyna, Richard J. Hall-Wilton, Douglas D. DiJulio +18
Instrument backgrounds at neutron scattering facilities directly affect the quality and the efficiency of the scientific measurements that users perform. Part of the background at…
