Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity... -
Excitations, BEC, and partially ordered states of liquid 4He in disorder
We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4... -
Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
