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... -
Neutron reflection from the surface of a liquid 3He-4He mixture
In our previous experiments we have investigated the surface properties of liquid 3He - 4He mixtures by neutron reflection. We have shown that in broad temperature range there... -
Neutron reflectometry study of liquid 3He/4He mixture surface
In our recent experiment RB1120146 we obtained exciting new results on neutron scattering from the liquid helium surface. At 2.3K there was no difference in reflectivity between... -
Quantum heating effect in molecular hydrogen
The goal of this proposal for beam time on MARI (direct geometry) is to independently confirm (or refute) our observation using VESUVIO (indirect geometry) of a novel quantum...
